After missing the playoffs last year, the Baltimore Kingfishers have returned to the playoffs in 4th place in the Eastern Division. That means they will now do battle with the Philadelphia Inventors, who finished 1st place in the Eastern Division with a 7.5-2.5 record and return to the playoffs for the 2nd straight year. Since Phildelphia is the higher seed, they will advance in the case of a drawn 2-2 match. They also received the choice of colors and picked to play white on Boards 1 and 3. Philadelphia leads the all-time series with a 8 match points against 5 match points for Baltimore. These two teams played in Week 1 this season, which ended in a draw. Five players (GM Erenburg, FM Gorman, IM Costigan, IM Enkhbat, and FM Zimmer) from that match return to play this one. All except two of the players (both board 3 players) in this match have playoff experience. Baltimore is 2-2 in playoff matches but they have not won since 2005. Meanwhile, Philadelphia is 0-2 in the playoffs.

Board 1: GM Sergey Erenburg vs. IM Tegshsuren Enkhbat. GM Sergey Erenburg, a former Baltimore Kingfisher, is (+4 =5 -1) in his 6th USCL season, (+1 =1) against Baltimore, and (+1 -1) in the USCL Playoffs. He won last week with black on Board 1 against GM Alexander Ivanov (NE). He placed 4th in the USCL MVP race, but surprisingly only 2nd on his team. In Week 1, he drew with white against his upcoming opponent, IM Tegshsuren Enkhbat. IM Enkhbat is (=3 -1) in his 8th season, (+3 =3 -1) against Philadelphia, and (=2 -2) in the Playoffs. He lost in Week 9 with white against IM Eli Vovsha (MAN) on Board 2.

Board 2: GM Larry Kaufman vs. FM Tom Bartell. GM Larry Kaufman is (+1 =2 -2) in his 8th season, (+2 =3 -3) against Philadelphia, and (+2) in the Playoffs. He lost last week as black against FM Kazim Gulamali (BOS) on Board 2. He has played twice with white (a draw in Week 4, 2009 and a loss in Week 2, 2008) against his opponent, FM Tom Bartell. FM Bartell is (+1 =1 -2) in his 6th season, (+1 =4 -1) against Baltimore, and (-1) in the Playoffs. He won last week with white against IM David Vigorito (NE) on Board 2.

Board 3: FM Dov Gorman vs. NM Kevin Wang. FM Dov Gorman is (+6 =2) in his first USCL season and (+1) against Baltimore. He won last week as black against Carey Theil (NE) on Board 3. With his impressive record, he placed 2nd in the USCL MVP race and first on his team. Also in his first USCL season, NM Kevin Wang is (+1 -1) and has not yet played against Philadelphia. He won in Week 8 with black against GM Boris Gulko (NJ) on Board 2.

Board 4: FM Ralph Zimmer vs. IM Richard Costigan. FM Ralph Zimmer is (+4 =1 -1) in his 7th season, (+4 =2) against Philadelphia, and (=1) in the Playoffs. He won last week against NM Ilya Krasik (BOS) with black on Board 4. That win gave FM Zimmer the slight half-point edge in the team MVP race. He has won twice (with white in Week 1, 2012 and with black in Week 8, 2009) against his opponent, IM Richard Costigan. IM Costigan is (=3 -1) in his 7th season, (+2 =3 -5) against Baltimore, and (-1) in the Playoffs. He drew with black against Nicolas Checa (NY) on Board 4 in Week 9.

The Baltimore Kingfishers clinched the 4th spot in the Eastern Division and a playoff spot with a win over the Boston Blitz. Baltimore finished the season with a 5.5-4.5 record, tied with New York though they took 3rd place on the first tiebreaker.

Board 1: The game began with a Queen's Gambit: Slav with white playing 4. Qb3 with a later fianchetto on the kingside. White's pair of bishops allowed him to win a pawn in the middle game. As boards 2 and 3 concluded, the match was tied 1-1 with board 4 looking unclear, so GM Margvelashvili had to press for the win. Then suddenly, FM Zimmer won his game and it became clear that Baltimore just needed a draw to win the match and secure a playoff spot, so GM Margvelashvili offered the clinching draw. He certainly could have played on to try to win in the final position:

Board 2: FM Gulamali won the Game of the Week and it is analyzed by GM Alex Yermolinsky on ICC. This very exciting game started as a French Defense: Steinitz, Bradford Attack. White castled queenside and aimed his pieces at black's kingside. FM Gulamali even sacrificed a knight to prevent a queen trade and open up the kingside. It looked like GM Kaufman should be able to hold the position, but he blundered with 26... Bg7:

FM Gulamali found a spectacular mate with 27. g6 Qf6 28. Rh8+! Bxh8 29. Qh7+ Kf8 30. Bb4+ Nd6 31. Bxd6+ Ke8 32. Qg8+ and blacked resigned before 32... Qf8 33. Qf8#.

Board 3: A Scotch Gambit transposed into a tame Two Knights Defense/Philidor Defense. NM Martirosov decided to allow his pawns to be doubled on the e-file and soon white won control of the open d-file. White managed to get his queen and rook lined up on the 7th rank and black had to look for a perpetual against the white king to try to survive. The perpetual just wasn't there as seen in the game when NM Defibaugh won, but there was a very interesting attempt not played after 36. Kh4:

If black tried 36... Rf4+, NM Defibaugh noted that 37. g4! wins with 37... Qf2+ 38. Kh5 Qxh2+ 39. Kg6 Rf6+ 40. Qxf6 gxf6 41. Ra8#. White had to avoid the mistake 37. gxf4? Qf2+ 38. Kg4 (38. Kh3? and Kh5? are actually forced mates for black! i.e. 38. Kh5 Qxf3+ 39. Kg6 Qxe4+ [not 39... Qg4+ 40. Qg5! with Ra8# coming] 40. Kh5 Qf3+ 41. Kg6 [41. Kh4 Qxf4+ 42. Kh5 Qf3+ 43. Kh4 g5+ and black will win the queen and rook] Qd3+ 42. Kh5 Qh3+ 43. Qh4 [43. Kg6 Qf5#] Qf5+ 44. Qg5 hxg5 and now black has h7 for the king) Qg2+ with a perpetual check.

Board 4: In what started as a Benoni, the game transposed into Queen's Gambit Declined and Queen's Indian lines. The game became very interesting when FM Zimmer sacrificed his two queenside pawns and a rook for a bishop and white's g-pawn to open up NM Krasik's king. Black's attack took a little while to develop and white missed some chances to defend better. For example, white could have played 27. Be4 with the idea of returning the exchange on d5 and 34. h3 instead of giving up the exchange with 34. Re4. Thus, black's adventurous play was rewarded and FM Zimmer ended the game with a picturesque queen sacrifice for mate with 43... Qd1+:
