First the U.S., now the world. With 2 1/2 points in the final three rounds, reigning U.S. national champion Gata Kamsky surged into a tie for first with English GM Michael Adams in the 39th annual World Open that wrapped up in Philadelphia last week. The New York GM then won a blitz playoff to snag bragging honors as the two former top-five grandmasters shared the $28,800 first prize.

Dutch GM Loek van Wely, who dealt Kamsky his only loss of the event, faded with two late losses to finish in a five-way tie for third, a half-point back.

The early rounds of these mega-Swiss events are typically tuneups for the top players, but there was an interesting moment in Kamsky’s Round 1 game against New York FM Kassa Korley. Spotting his opponent more than 400 rating points, Korley puts up an unexpectedly tough fight before succumbing.

In a Caro-Kann, Kamsky as White is willing to accept a clogged-up pawn center for a clear spatial edge. Give Black credit for not going down meekly with his 15. Rb1 g5!? 16. Nf3 h6 17. Re2 Ng6, and in the ensuing complex tactical play, he may have missed a shot that would have made the grandmaster sweat.

Critical was 27. Rxb6 Nf4 28. Nc5 Ra2 29. dxe5!?, when 29…Qc7! sets real problems for White. Kamsky’s back-rank vulnerability would cost him in lines such as 30. Qxb4 Rc8! (less convincing is 30…Ne2+ 31. Kf1 Nxc1 32. Nxe6) 31. Kf1 Qxc5! 32. Rxc5 Ra1+ 33. Qe1 Rxe1+ 34. Kxe1 Nxd3+ 35. Kd2 Nxc5.

After the less effective 29…Nxg2?! 30. Nxe6 Nh4 31. Qe3!, White regains the tactical whip hand, nicely turning back Black’s attempts to press his attack.

Korley’s little combination to “win” the exchange ends up permitting White a devastating final attack on 32…Qh5 33. Rxb4! Qg4+ 34. Qg3 Nf3+ 35. Nxf3 Qxb4 36. Nxg5!, destroying the Black’s king’s defenses.

It’s over after 36…Kh8 (hxg5 37. Qxg5+ Kf8 [Kh8 38. Rc6] 38. Qf5+ Kg8 39. Kh1 and wins) 37. Rc6, and Black resigns in light of lines like 37…hxg5 (Qf8 38. Qh3) 38. Rh6+ Kg7 39. Qxg5+ Kf7 40. Rh7+ Ke6 41. Qf6 mate.

Virginia expert Eric Most, playing in the Open section, had a fine stay in Philadelphia, drawing an IM, notching a couple of upset wins, and even taking second in the side Game/10 tournament held in conjunction with the main event. Today’s diagram, taken from Most’s Round 4 game against Michigan master Seth Homa, is a nice illustration of the axiom that sometimes it is better to be lucky than good.

Most, playing White, is looking grim here, down a pawn and facing a powerful Black bishop in the ending where even a draw would be a minor miracle. Having just played 39…Bc3-e5. Homa threatens to win on the move with 40…f5, but things take a surprising turn.

Thus: 39. g4 Kf8 40. Kd3 Ke7 41. Nd2 h5?! (one can see the idea here, but Black is in the midst of outsmarting himself) 42. gxh5 (why not?) Bh2? (preparing to put the bishop on precisely the wrong diagonal) 43. Nc4 Bg1 44. h6 Kf6 45. Ne5!, and the knight can’t be captured or the pawn queens.

Unfortunately for Black, the same principle applies after 45…Bc5 46. h7 Kg7 47. Nxf7! Kxh7 48. Nxg5+, and, suddenly, it’s White who is now a pawn up. Stunned by the turn of events, Black goes down meekly after 48…Kg6 49. Ne4 Bg1 50. Kc4 Kf5 51. Nc3 Ke5 52. Nd5 Ke4 53. h4, resigning as he can’t stop the outside passed pawn and preserve his queen-side pawns at the same time.

We wrap things up with another Caro-Kann, taken from a tournament last month in Voronezh, Russia, where once again the lower-rated Black player — Russian master Eduard Barsamian — missed a real chance to make things more interesting.

U.S.-born IM Rashid Ziatdinov, playing White, shows his aggressive intentions early with 17. Qe3 Qb6 18. Ngf5!? Bd8 19. Qg3, virtually forcing Black to take the offered piece. Barsamian tries not to be greedy, but this time it backfires for the defender.
