The Baltimore Kingfishers lost 1-3 to the Boston Blitz in the final week of the regular season. Baltimore finishes 4th in the Northeast Division with a (3.5-6.5) match record while Boston places 3rd with a (4.5-5.5) record. In other divisional news, the New England Nor'easters and Connecticut Dreadnoughts drew their match, so New England (7.0-3.0, 1st) will get draw odds while Connecticut (6.5-3.5, 2nd) gets color choice in their Quarterfinals showdown.

Board 1: GM Niclas Huschenbeth vs. IM Steven Zierk. The top board showcased a Sveshnikov Sicilian Defense: Chelyabinsk variation. White offered the h-pawn which black accepted and a trade of rooks from diagonally-opposite corners ensued. GM Niclas Huschenbeth played the surprising resource 18. Ne3 as the novelty. Then, queens were traded and white was left with an extra knight for two pawns. Although the queens were off, it was a very interesting game with black creating a 5-pawn-wall from the kingside to the center after move 31 and clearly aiming to march the h-pawn to promotion. Meanwhile, white tried to nurse a long-term advantage with his queenside pawns. It seems white should have been better until the dual-mistakes 33. a3? and 34. axb4? which cost white his bishop to stop the black h-pawn. IM Steven Zierk pounced on the opportunity and easily converted the ending up only an exchange. White resigned after move 50.

Board 2: SM Denys Shmelov vs. IM Tegshsuren Enkhbat. The second board featured a Slav Defense: Chebanenko variation. IM Tegshsuren Enkhbat played the novelty 10... Nhf6 whereas 10... Bg6 had been played twice before resulting in draws (Note: Two of the stem games coincidentally feature former Dallas players, GM Valentin Iotov and IM Puchen Wang). Black tried to open up the queenside to play with 12... b6 but this plan seemed to backfire as SM Denys Shmelov chased away the black queen and exploited the c-file with his rooks. From that point onward, white was clearly better though black tried to drum up an attack on the kingside. However, NM Shmelov's control of the board was too great and black resigned on move 41.

Board 3: NM Jared Defibaugh vs. NM Vadim Martirosov. The third board saw NM Jared Defibaugh's King's Gambit answered with the Falkbeer Counter-Gambit by NM Vadim Martirosov. The move 4. Bc4 is very rarely played for such an early move, so NM Defibaugh was probably trying to avoid theory in this game. He later played the novelty 7. Bb5+. White returned the counter-gambit pawn on d4 and the queens were traded. The two players castled on opposite sides but play was focused in the center with black trying to bolster his passed e-pawn. White missed a surprising chance on move 23 to get compensation by allowing the e-pawn to promote while taking a rook with check (!) though black would have to give up a knight as well. Two pawns for the exchange and the result would have still been unclear. Soon after, it was black who missed a clear win on move 25, but all was not lost as white was still in a bind due to black's pawn on e2. NM Martirosov did not miss another chance and converted to a won ending with an extra bishop. White resigned after 42 moves.

Board 4: NM Daniil Mosiyenko vs. Jeffrey Chang. The fourth board began with another sharp Sicilian Defense, but this time, it was the Classical Main Line of the Najdorf variation. These two young players zipped through theory nearly until Jeffrey Chang played the novelty 18... Nf6. Note that one of the stem games was played by GM Niclas Huschenbeth, who was playing on Board 1 in this match. I have to seriously wonder if Jeffrey knew this game while playing as he first sank into deep thought when NM Daniil Mosiyenko varied from that game on move 18 and both endings had similar ideas. I am only aware that Jeffrey is being coached by GM Larry Kaufman, not GM Huschenbeth! Despite being down a pawn out of this opening line, black seemed to have a solid position with plenty of control. When it came down to a pawn race, black's kingside pawns were much faster than white's queenside pawns. It also helped that black ended up with a bishop vs. knight in the ending. There was a bailout to a drawn rook and bishop vs. rook and pawn ending that white missed, but practically, that ending would still be difficult to hold. Thus, Jeffrey Chang won his USCL debut in 61 moves.

Finally, in Baltimore's Team MVP standings, Jeffrey Chang tied FM Ralph Zimmer for the lead with 3.5 MVP points though FM Zimmer wins the title (on most games played tie-break) for the second year in a row. Thanks to everyone for playing, watching the games, reading articles, and voting in polls. We look forward to a great season next year!

Note: Players in italic have the white pieces.

The Baltimore Kingfishers (3.5-5.5, 4th place) and the Boston Blitz (3.5-5.5, 3rd) square-off to determine 3rd place in the Northeast Division. Boston leads Baltimore 16-15 in total game points this season for the first tie-break. Neither team can make the playoffs, so it will be the last game of the year for both teams. Boston leads the all-times series against Baltimore with a 7-6 match score. These two teams last played in Week 5, 2013 when all boards were drawn. Three players (IM Tegshsuren Enkbat, SM Denys Shmelov, and NM Vadim Martirosov) from that last match return to play in this match as well.

Board 1: GM Niclas Huschenbeth vs. IM Steven Zierk. GM Niclas Huschenbeth is (+1 =1 -1) in his 2nd USCL season and has not played against Boston previously. He drew last week with the white pieces against GM Mikheil Kekelidze of the Connecticut Dreadnoughts on Board 1. He is matched up with IM Steven Zierk, who is (+1 -1) in his 3rd USCL season but has not played against Baltimore in his career. He won last week with the white pieces against GM Alexander Ivanov of the New England Nor'easters on Board 1.

Board 2: SM Denys Shmelov vs. IM Tegshsuren Enkhbat. SM Denys Shmelov is (+2 =5 -1) in his 6th season and has a (+1 =3 -1) record against Baltimore.

He won last week with the black pieces against FM Charles Riordan of the New England Nor'easters on Board 2. He is rematched with IM Tegshsuren Enkhbat, who has a (+1 =3 -2) record in his 9th season and has scored (+2 =3 -3) against Boston in his career. IM Enkhbat last played in Week 8 when he drew with the white pieces against FM Steven Winer of the New England Nor'easters on Board 2. SM Shmelov and IM Enkhbat played against one another in a drawn game from Week 5, 2013.

Board 3: NM Jared Defibaugh vs. NM Vadim Martirosov. NM Jared Defibaugh is (+2 =3 -3) in his 4th season and has a (+2) score against Boston. The only match he did not play this year was Week 5 when Baltimore played against the Boston Blitz. He lost last week with the white pieces against FM Leif Pressman of the Connecticut Dreadnoughts on Board 3. He will battle NM Vadim Martirosov, who is (+2 =2 -1) in his 7th USCL season and has a (=6 -1) record against Baltimore. He won in Week 8 with the black pieces against IM Jay Bonin of the Connecticut Dreadnoughts on Board 3. NM Defibaugh and NM Martirosov also played against one another with the same colors in Week 10, 2012 when NM Defibaugh won.

Board 4: NM Daniil Mosiyenko vs. Jeffrey Chang. NM Daniil Mosiyenko is making his season debut for the Boston Blitz. He played 3 games in 2011 with a (+1 =1 -1) record for Boston.

Week 9 Review

Baltimore Kingfishers vs. Connecticut Dreadnoughts 0.5-3.5
GM Niclas Huschenbeth (2610) - GM Mikheil Kekelidze (2576) 0.5-0.5 View Games
GM Larry Kaufman (2401) - IM Justin Sarkar (2512) 0-1 View Games
NM Jared Defibaugh (2297) - FM Leif Pressman (2374) 0-1 View Games
FM Ralph Zimmer (2244) - Jason Shi (2173) 0-1 View Games

Note: Players in italic have the white pieces.

The Baltimore Kingfishers lost to the Connecticut Dreadnoughts by a dreadful 3.5-0.5 score. That leaves Baltimore out of the playoffs this year with the New England Nor'easters (6.5-2.5, 1st) and Connecticut Dreadnoughts (6.0-3.0, 2nd) clinching the top 2 spots in the Northeast Division. Those two teams will battle next week to determine playoff seeding and the oft-important draw odds when they meet again in the Quarterfinals. Meanwhile, the Baltimore Kingfishers (3.5-5.5, 4th) will face the Boston Blitz (3.5-5.5, 3rd) to determine third place in the division.

Also, there was an unusual circumstance on board 3. Baltimore's player NM Jared Defibaugh was granted permission by the league to play from his home as his neighborhood was undergoing a police search for a man who shot an officer. Thankfully, the suspect has been caught, but that did not happen until the day after the match. Read more about the news story at: CBS Baltimore News.

Board 1: GM Niclas Huschenbeth vs. GM Mikheil Kekelidze. The top board showcased a Ruy Lopez: Open Berlin Defense, Rosenthal Variation. NM Niclas Huschenbeth played the novelty 12. g4 that proved quite risky as GM Mikheil Kekelidze was able to open the h-file to threaten the white king. It looked like white was in dire straits but somehow the white king found himself relatively safe back towards the center back rank and found himself up a knight for some pawns with queens and rooks still on the board. White seemed to have gained the upper hand and forced trades of the rooks and queens. It was a white knight and 2 pawns vs. 5 pawns for black, yet it was black who seemed to be pushing for a win again. However, white's king and knight were up to the task of blockading though no more as the game was drawn by 3-fold repetition after 64 moves.

Board 2: IM Justin Sarkar vs. GM Larry Kaufman. The second board featured a Nimzo-Indian Defense: Botvinnik System. IM Justin Sarkar played the novelty 13. Bb2 and GM Larry Kaufman responded with the very ambitious 13... e5!? intending a knight sacrifice. However, in what turned out to be the critical moment of the game, he slipped with 19... Ba6? 20. c4 Bxc4 allowing a nifty tactic that loses his queen. GM Kaufman saw the tactic immediately after playing Bxc4, and unfortunately, so did his opponent. Black resigned in 28 moves. There were some interesting possible lines in the critical position. Check them out in the board analysis!

Board 3: NM Jared Defibaugh vs. FM Leif Pressman. The third board began as a Sicilian Defense with the relatively rare variation 2. Nf3 e6 3. b3. NM Jared Defibaugh played the novelty 10. Nc3. The moves 10. Na3 (7 White wins, 13 Draws, 2 Black wins) and 10. d4 (1 White win, 2 Draws) have been played previously. White tried to create an attack on the kingside, but FM Leif Pressman thwarted that plan by forcing a queen trade. Black quickly gained a space advantage as the white rooks had no clear targets. Black won a pawn and then a rook as white tried to keep chances on the board. White resigned after 47 moves.

Board 4: Jason Shi vs. FM Ralph Zimmer. The fourth board saw a Benko Gambit played. Jason Shi played the novelty 8. e5. Surprisingly, white had always played 8. Bxc4 (1 White win, 1 Draw, 6 Black wins) each time this position was reached. FM Zimmer appeared to be allowing white to gain space in the center perhaps anticipating that white would overextend himself. White did march his pawn to e6, but black missed some chances to create an unbalanced position. White gradually gained an advantage using his more mobile pieces. Black resigned on move 42.

Week 9 Lineup

Baltimore Kingfishers vs. Connecticut Dreadnoughts
GM Niclas Huschenbeth (2610) - GM Mikheil Kekelidze (2576)
GM Larry Kaufman (2401) - IM Justin Sarkar (2512)
NM Jared Defibaugh (2297) - FM Leif Pressman (2374)
FM Ralph Zimmer (2244) - Jason Shi (2173)

Wednesday, 7:20 PM EDT
Time Control: 75 min. with 30 sec. increment

Note: Players in italic have the white pieces.

The Baltimore Kingfishers (3.5-4.5, 3rd place) battle the Connecticut Dreadnoughts (5.0-3.0, 2nd place) in a race to secure the 2nd playoff spot in the Northeast Division. Connecticut is 1.0 match point behind the 1st place New England Nor'easters, and the 1st place team in each division gets to choose either draw odds or color choice in the Quarterfinals of the playoffs. Baltimore needs to win this match to have any chance of overtaking Connecticut in the final week of the regular season. Baltimore is also behind with 14.5 game points (the first tie-break) to Connecticut's 18.0 game points thanks to Connecticut's 4-0 sweep of Baltimore the last time they faced-off in Week 1 of this season. Surprisingly, that means Baltimore has outscored Connecticut by 0.5 game points but Connecticut has outscored Baltimore by 0.5 match points after Week 1. Connecticut leads the all-time series 1.5-0.5 in match points. Three players (GM Mikheil Kekelidze, NM Jared Defibaugh, and Jason Shi) return from that last match to play in this match, too.

Board 1: GM Niclas Huschenbeth vs. GM Mikheil Kekelidze. GM Niclas Huschenbeth is (+1 -1) in his 2nd USCL season and has not played against Connecticut previously. He won in Week 7 with the white pieces against GM Emil Anka of the Seattle Sluggers on Board 1. He is matched up with GM Mikheil Kekelidze, who is (+2 =2 -1) in his 2nd USCL season and has scored (+1 =1) against Baltimore. He last played in Week 5, when he won with the black pieces against GM Sam Shankland of the New England Nor'easters on Board 1.

Board 2: IM Justin Sarkar vs. GM Larry Kaufman. IM Justin Sarkar lost his only game of the season in Week 7 with the white pieces against IM Levon Altounian of the Arizona Scorpions on Board 2. He has yet to play against Baltimore in his 3 USCL seasons. His opponent, GM Larry Kaufman, has a (=1 -2) record in his 9th season and drew his only career game against Connecticut. He lost in Week 7 with the black pieces against FM Costin Cozianu of the Seattle Sluggers on Board 2.

Board 3: NM Jared Defibaugh vs. FM Leif Pressman. NM Jared Defibaugh is (+2 =3 -2) in his 4th season and has a (-2) record against Connecticut. He drew last week with the black pieces against NM Mika Brattain of the New England Nor'easters on Board 3. He is set to play against FM Leif Pressman, who is (+1 =1) in his 2nd season but has not played against Baltimore. He drew in Week 7 with the black pieces against IM Mark Ginsburg of the Arizona Scorpions on Board 3.

Board 4: Jason Shi vs. FM Ralph Zimmer. Jason Shi is (+1 =1) in his first USCL season and won his only game against Baltimore. He last played in Week 4, when he drew with the black pieces against Jacob Wilkins of the St. Louis Arch Bishops on Board 4. He will square-off against FM Ralph Zimmer, who is (+2 =1) in his 8th year in the USCL and won his only career game against Connecticut. He won last week with the white pieces against NM Andrew Liu of the New England Nor'easters on Board 4.

Week 8 Review

New England Nor'easters vs. Baltimore Kingfishers 1.5-2.5
GM Sam Shankland (2673) - IM Levan Bregadze (2469) 0.5-0.5 View Game
FM Steven Winer (2409) - IM Tegshsuren Enkhbat (2492) 0.5-0.5 View Game

Note: Players in italic have the white pieces.

The Baltimore Kingfishers defeated the New England Nor'easters by a 2.5-1.5 score to keep their playoff hopes alive. Baltimore is now (3.5-4.5) and in 3rd place in the Northeast Division. Despite the match loss, New England (6.0-2.0) has clinched a playoff birth due to the Connecticut Dreadnoughts (5.0-3.0) beating the Boston Blitz (3.0-5.0) in the other Northeast Division match of the night. Next Wednesday, Baltimore will face the 2nd place Connecticut Dreadnoughts when Baltimore must win the match to have a chance at overtaking Connecticut for the final playoff spot in the Northeast Division. Check out the New Jersey Knockout's Blog for the Northeast Division playoff scenarios.

Here is a puzzle to start off this week's review. Its significance shows up in the Shankland-Bregadze game analysis. Black to play and win:


Board 1: GM Sam Shankland vs. IM Levan Bregadze. The top board began with a Neo-King's Indian Defense: Torre Attack. IM Levan Bregadze played the novelty with 14... a6. Black looked to be clearly worse after 22. Nxg5 hxg5 23. Bxg5 as he had hanging pawns on b5, d6, and e4, little development, and a queen that's shut-in mostly by her own pieces. Somehow, black was only down a pawn after some trades, and then, GM Sam Shankland sacrificed the exchange to win another pawn and reach a favorable position with a bishop and 2 pawns for a rook. While IM Bregadze was clearly trying to trade the queens off the board, he made a mistake with 41... Qd6, but white missed 42. Qf5 (with Bd5 coming) winning at least the f7-pawn. Later, the queens were finally traded, but white was still pressing for a win especially with more than half an hour left on his clock. However, white slipped up when he dropped a bishop probably thinking he had tricked black into a losing position. Instead, white ended up down in a rook+pawn vs. bishop+pawn ending that the endgame tablebases show as a mate in 28 for black. However, it was not so easy to find the win for black especially in time pressure, so the game ended up drawn by 3-fold repetition in 107 moves.


Board 2: IM Tegshsuren Enkhbat vs. FM Steven Winer. The second board started with a Slav Defense with 4.Qb3 that transposed into a Closed Catalan Opening. IM Tegshsuren Enkhbat played the novelty 17. Ra6. Play was focused on the queenside until the queens and queenside pawns were traded off. White had the space advantage and tried to create some imbalances on the kingside, but FM Steven Winer kept the game under control. Unlike the first board, this game did not stray far from even throughout, and on move 90, it also ended as a draw by 3-fold repetition.


Board 3: NM Mika Brattain vs. NM Jared Defibaugh. The third board saw a Leningrad Dutch Defense. In the line these two played, black seems to be willing to sacrifice 2 pawns (maybe even 3 pawns in some cases) to open up the position and activate all his pieces. NM Mika Brattain returned one of two sacrificed pawns with novelty with 14. Nf6+. He also avoided playing Qxb7 several times to prevent black from getting a very active position. Then, he sacrificed an exchange to keep a very annoying e-pawn. NM Jared Defibaugh returned the exchange to trade off queens and get rid of the e-pawn. He ended up down a pawn in the ending, but with a pair of bishops vs. knight+bishop. White managed to trade his knight for a bishop, but the resulting opposite-colored bishop endgame was drawn despite black being down a pawn. A draw was agreed after 52 moves by each player.


Board 4: FM Ralph Zimmer vs. NM Andrew Liu. The fourth board featured a Trompowsky Attack with 2... c5. NM Andrew Liu was using up most of his time in the opening, but he ended up playing a novelty with 7... Bg7. Then, came a strange technical error on move 9. FM Ralph Zimmer played 9. Bc4 on his board and waited in his seat for his opponent to move. About 30 minutes later, NM Defibaugh passed by my computer (as TD, I have all games up on one screen) and noticed it was FM Zimmer's turn to move after black played 9... e6 but the move was not showing up on FM Zimmer's screen. I went to FM Zimmer's computer to refresh Live Chess and the move 9... e6 showed up, but 20+ minutes of FM Zimmer's time had elapsed. I informed the overall league TD of the situation. Then, FM Zimmer noticed that his bishop was showing up on e2 instead of c4 as he had played, which was confirmed to me by both NM Defibaugh and IM Bregadze as they often get up to observe teammates' games. I also informed the league of this error, but advised FM Zimmer to keep playing while the league investigated. Apparently, a similar technical error (only the opponent's move not showing up part) occurred to NM Bryan Hu on Board 4 in Week 2 noted by IM Greg Shahade on the Wednesday night's Chess.com/tv broadcast and in the Week 2 blog for the Arizona Scorpions. Anyway, after the league and chess.com staff confirmed the error, the game and times were reset to before white's move 9. White was on the offensive on the kingside, especially with the open g-file, but had to retreat his queen as black prevented backup from arriving. Then, black grabbed space in the center and tried to attack using the a-file. White stopped the attack and then used the abandoned g-file for his own renewed attack. Black finally fell to a knight-fork tactic that wins a queen for a rook, so he resigned on move 48.

Week 7 Review

Baltimore Kingfishers vs. Seattle Sluggers 2-2
GM Niclas Huschenbeth (2610) - GM Emil Anka (2497) 1-0 View Game
GM Larry Kaufman (2401) - FM Costin Cozianu (2478) 0-1 View Game
NM Jared Defibaugh (2297) - FM Tian Sang (2324) 0-1 View Game
FM Ralph Zimmer (2244) - FM Curt Collyer (2266) 1-0 View Game

Note: Players in italic have the white pieces.

The Baltimore Kingfishers drew the match against the Seattle Sluggers. Baltimore in still in 4th place in the Northeast Division with a (2.5-4.5) record. The Kingfishers gained ground on the Boston Blitz, who lost to the San Francisco Mechanics, but more pertinently, they lost ground to the Connecticut Dreadnoughts, who increased their hold on 2nd place in the division after defeating the Arizona Scorpions. Meanwhile, the New England Nor'easters trounced the Los Angeles Vibe, so New England only needs half a match point to guarantee themselves a playoff spot. Only the top 2 teams in each division make the playoffs. Baltimore can still make the playoffs by doing well in the final 3 weeks as they are all divisional games. Next up is New England on Tuesday.

Board 1: GM Niclas Huschenbeth vs. GM Emil Anka. The top board showcased a Maroczy Bind against the Sicilian Defense: Accelerated Dragon. GM Niclas Huschenbeth played the novelty 18. a3 to lockdown black's pawn on a4. White aimed to round up that a4 pawn, which happened a few moves later. Black got the f-pawn in exchange, but white got that back a few moves later again. In the double-rook endgame, white increased his one pawn advantage to a three pawn advantage before GM Emil Anka resigned.

Board 2: FM Costin Cozianu vs. GM Larry Kaufman. The second board began with white playing the Sicilian Defense: Rossolimo Varation but soon transposed into another Maroczy Bind structure. GM Larry Kaufman played the novelty 12... Rb8. Then, FM Costin Cozianu complicated and opened up the position with 14. e5. After a series of exchanges, white had 2 bishops, a rook, and 6 pawns against 2 rooks, a knight, and 5 pawns. GM Kaufman then marched his a-pawn and sacrificed it to break up white's queenside structure. Black looked to be making progress until 38... Nxf3 when 39. Bc1 surprised GM Kaufman, who was playing with only the increment left on his clock. In that time pressure, he missed the only move 39... Rd1+ intending to sacrifice back the exchange on c1. He resigned on move 50.

Board 3: NM Jared Defibaugh vs. FM Tian Sang. The third board featured a Nimzo-Indian Defense: Reshevsky Variation. NM Jared Defibaugh played the novelty 11. Qf3. Three other moves had been tried in that position: 11. b4 (1 White win, 2 Draws, 2 Black wins), 11. f3 (1 White win, 1 Black win), and 11. Re1 (1 Black win). The game seemed about even until NM Defibaugh played the break 17. e4 dxe4 18. Nxe4? (18. Bxe4 would have lost a pawn, but white would still have a good chance to draw) which simply lost to the line FM Tian Sang played as black in the game. NM Defibaugh resigned on move 23 as the Qg1 mate threat would cost too much material to stop.

Board 4: FM Curt Collyer vs. FM Ralph Zimmer. The fourth board displayed a Richter-Veresov Attack: Veresov Variation. FM Ralph Zimmer played the novelty 10... g6. Then, he expanded on the queenside with his pawns before turning to take control of the open e-file. After a pair of rooks and the queens were exchanged, FM Zimmer broke open the queenside with 30... a3 and soon created an unstoppable passed pawn with 34... b4 taking advantage of the awkward placement of white's rook on f3. FM Curt Collyer resigned after move 38 when it was clear to all that black's b-pawn would promote.

The Baltimore Kingfishers (2.0-4.0, 4th place) of the Northeast Division take on the Seattle Sluggers (2.5-3.5, 2nd place) of the Pacific Division in Week 7 of the US Chess League. This is the 2nd and last week of East vs. West interconference play in the regular season. Both teams lost in Week 4, the first week of interconference play. Seattle lost to Philadelphia 1-3 while Baltimore went down to Dallas with a 1.5-2.5 score that week. However, both teams won last week with Baltimore beating Philadelphia 3-1 and Seattle defeating Dallas 2.5-1.5, stopping Dallas' 5-match win streak. Interesting transposition between the four teams, right? Now, Baltimore and Seattle have only battled each other once before in Week 4, 2012, and Seattle won that match with a 2.5-1.5 score. Two players (FM Costin Cozianu and FM Curt Collyer) from that match return to play in this match, too.

His opponent, GM Larry Kaufman, has a (=1 -1) record this year and has played in all 9 years of the USCL yet has not had a game against Seattle until this match. He drew in Week 5 with the black pieces against NM Vadim Martirosov of the Boston Blitz on Board 3.

Week 6 Review

Baltimore Kingfishers vs. Philadelphia Inventors 3-1
IM Levan Bregadze (2469) - FM Tom Bartell (2496) 0.5-0.5 View Game
IM Tegshsuren Enkhbat (2492) - FM Dov Gorman (2362) 0.5-0.5 View Game
NM Jared Defibaugh (2297) - NM Peter Minear (2385) 1-0 View Game
NM Ian Schoch (2296) - FM Karl Dehmelt (2260) 1-0 View Game

Note: Players in italic have the white pieces.

The Baltimore Kingfishers improve to a (2.0-4.0) record by defeating the Philadelphia Inventors with wins on boards 3+4 and draws on the top 2 boards. That leaves Baltimore still in 4th place in the Northeast Division, but they are now only 1 match point behind the 2nd and 3rd place teams, the Connecticut Dreadnoughts and the Boston Blitz, respectively. New England is in clear 1st place with a (5.0-1.0) record, having a 2.0 match point lead over Connecticut and Boston. Next week, the USCL features another set of East vs. West matches, so the Baltimore Kingfishers and the Seattle Sluggers will tee-off on Tuesday night.

Board 1: IM Levan Bregadze vs. FM Tom Bartell. The top board transposed from a Reti Opening into an English Opening: Symmetrical Defense, Hedgehog System. The game apparently followed the same line as a master-level game played in England in 2007 up to 16. exd6. FM Bartell differed with the novelty 16... Bxd6. IM Levan Bregadze tried to create some interesting play in the center and pointing towards black's king, but FM Bartell was able to defend rather easily. They agreed to a draw on move 27, which made it the first USCL game on the night with a result.

Board 2: FM Dov Gorman vs. IM Tegshsuren Enkhbat. The second board showcased a Caro-Kann Defense: Panov-Botvinnik Attack. Two other games had reached the position after move 10, and they both saw a different capture on d5 and both games ended in a draw. Our USCL game showed the 3rd possible capture on d5 with FM Gorman playing the novelty 11. Nxd5, and the game also eventually ended in a draw. After the exchanges on d5, white came out with an extra pawn, but it was doubled and isolated on the d-file. Later, FM Gorman tried opening up black's kingside, but IM Tegshsuren Enkhbat countered by occupying the h-file with his own rooks and queen. Just as the position was looking double-edged, all the rooks and queens were traded. That left a position with opposite-colored bishops and 3 pawns each, so a draw was agreed.

Board 3: NM Jared Defibaugh vs. NM Peter Minear. The third board displayed a King's Indian Defense: Samisch Variation. NM Peter Minear played the novelty 12... Bb7. White looked to be much better as the kingside attack was advancing quickly. The move 19. g5 seems to win black's knight, but NM Jared Defibaugh played 19. Bg5 instead. Perhaps looking for a quick knockout after g5 and not finding one, he chose an alternative. Even after this mistake, white soon came out up a knight for 2 pawns. Then, he held back black's attacking chances and slowly found a way to make use of his extra knight. Particularly nice was a tactic that began with 44. Rxh4+! that forced some trades and neutralized black's attack. The game went on for awhile until finally black resigned on move 87. This was the final game of the night to finish.

Board 4: FM Karl Dehmelt vs. NM Ian Schoch. The fourth board featured an Alekhine's Defense: Exchange variation that was blitzed out by NM Ian Schoch. He had to play fast as he arrived very late, so he was under 30 minutes from the start. NM Schoch played the novelty with 17... N8e7. Amazingly, he was about even on time (with both players having about 25 minutes left) when the critical moment of the game arose with the surprising sacrifice 20. Bxd5?! by FM Karl Dehmelt. The tactics left white with a rook to black's knight and bishop. NM Schoch converted that advantage quite adeptly as the game ended before move 39 with a forced mate on the board.
