WCC 2011 Championship Match (Rd 3), Dec 13.2011

Game 3 was delayed a week due to Dr. Kistler’s professional schedule. Mr. Prieto used the time wisely to review game one. Dr. Kistler again opened with the Ruy Lopez line 1.e4 e5  2.Nf3 Nc6 3. Bb5 a6, and a repeat of game one was in the offering. Mr. Prieto found an improvement to his seventh move of game one with 7….Bd7, allowing a Queenside castle on 8…0-0-0. Dr. Kistler needed to adjust his game plan and attack the Black King: for instance, moving 13. N4b3 instead of the pawn push 13.f5 would have forced the exchange of the dark squared Bishops and offered a White attack on the diagonal g1-a7. White’s move 14.c3 again should have been 14.N4b3 forcing the exchange of the Bishops. White’s position, by now quite cramped, was further aggravated by move 15.N4f3. Black captured the Knight with 15….Bxf3, leading to his advantage of two minor pieces for a rook. At this point, with White trying to extradite himself from his somewhat cramped position, Black waited for just the right moment to spring into further action. White’s 23. Rg1 was the right moment for Black’s 23….Ng3+, forcing White to trade his Queen for the two Black minor pieces. Now Black, just needed to mop up for the upset win.

2011 WCC Championship Rd. 2

Posted on March 11, 2012 by Watertown Chess Club

GAME 2-Dec 6,2011

Mr. Prieto, playing white in game two, seemed surprised by Dr. Kistler’s “Old Benoni” defense to 1.d4 with 1…c5. By move 11, an even position had settled in. By move 22, Mr. Prieto had built a slight positional edge, holding the center while Dr. Kistler‘s bishops countered with their long-range control. However, as we have all experienced, the superior position disappear in a heartbeat. Mr. Prieto’s move 23. f4 followed later by 25. fxg5 seemed to overreach and the battle was on. It appeared Dr. Kistler would exploit yet another seemingly logical attacking move and sweep the tournament. Dr. Kistler had the potential killer move of 23….d5 24. Ne5  Re6 25. fxg5, and now the punishing pawn move 25…d4 would force the White Queen Knight to the back rank. Now 26….hxg5 27 Bxg5 liberates Black’s Queen with 27…Qd5 and White’s King position would be under great stress.

Not so fast! In a tactical position nightmare Dr. Kistler’s capture 25. hxg5 allowed White to escape certain disaster and regain a brief advantage. Time pressure took a great toll on both players in this seesaw game as both erred down the stretch. Black missed the opportunity to invade with his Rook by 36…Nf6 37 Rg5 Rd2 and then on the move 39…b5? which again should have been 39….Nf6, he lost a piece to the Knight fork. White, also suffering time pressure with less than 3 minutes on his clock missed the win, giving back the piece with 45. Nxc5 Bd4+. White, under heavy time pressure accepted Black’s draw offer, leaving Dr. Kistler 1 draw from another title.

2011 WCC Championship Rd. 1

Posted on March 11, 2012 by Watertown Chess Club

Dr. Kistler won an intense first round game, playing the White side of the exchange version of the Ruy Lopez. Kistler slowly built a slight positional edge and then sprung a nice combination to trade down pieces with 24. Ne7+!. White’s capture on 26. Rxd7 landed the White Rook on the seventh rank and forced the loss of the now backward black c6 pawn. Black resigned when White’s King reached Black’s back rank with 62.Kb8, guaranteeing a new White Queen. Dr. Kistler now appeared ready to cruise to a second championship. A second win or two draws would clinch the championship. Mr. Adolfo Prieto, a Category 1 player and the 2008 and 2009 club champion, didn’t seem to get that memo.
