"In the laboratory, gambits all test unfavorably; but the old rule wears well, that all gambits are sound over the board."

NM Michael Pearson won the Irving Chernev Memorial Tuesday Night Marathon with 7 from 8. Tying for second with six points in the upset-filled 60-player event were Expert Igor Traub and A-players Dante Argishti and Hayk Maneleyan. The Fall Marathon, a ten-rounder, starts October 14.

IM Ricardo DeGuzman bounced back from a sub-par result in the Irving Chernev Memorial Tuesday Night Marathon to tie for first in the 8th Annual Howard Donnelly Memorial G/45 last Saturday. DeGuzman defeated his chief rival, IM Andrei Florian, in round 4 and then drew co-champion teenager Michael Lin in the last round.

This season the Bay Area entry in the US Chess League has played below its potential but it took until round five to receive justly deserved punishment. In the three and half seasons of the USCL this match has to rank among the worst if not the worst match we have played. Hopefully it will be a wake up call.

San Francisco vs Boston

1. IM Vinay Bhat (SF) vs GM Larry Christiansen (BOS) 0-1
2. SM Jorge Sammour-Hasbun (BOS) vs IM David Pruess (SF) 1-0
3. FM Sam Shankland (SF) vs NM Marc Esserman (BOS) 1/2-1/2
4. NM Ilya Krasik (BOS) vs FM Daniel Naroditsky (SF) 1/2-1/2

Sammour Hasbun,Jorge (2576) - Pruess,David (2479) [C14]
1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Be7 5.e5 Nfd7 6.Bxe7 Qxe7 7.f4 0-0 8.Nf3 c5 9.Qd2 Nc6 10.0-0-0 Normally White plays 10.dxc5 but the text is not unknown. 10...c4 David takes up the challenge. Jorge, who prepares quite seriously for his games, was no doubt familiar with a game David played with Alan Stein in this variation. 11.g4 Rb8 12.Nb5 Nb6 13.h4 This and White's follow up with 15.f5 are what makes this game unique to others with 10.0-0-0 c4. Weeks could be spent analyzing the pros and cons of this approach. 13... Bd7 14.Nd6 Nc8 15.f5 Nxd6 16.f6 gxf6 17.exd6 Qxd6 18.Qh6 Qe7 19.g5 f5 20.h5 Kh8 21.g6 f6 22.Rg1 Rg8 23.Nh4 Qg7 24.Qe3 h6 25.Ng2 Rge8 26.Nf4 Kg8 27.Bg2 b5 28.Rge1 a5 29.Re2 b4 30.Rde1 Qf8 31.Nxe6 Bxe6 32.Qf4 Bd7 33.Bxd5+ Kg7 34.Qc7 Rxe2 35.Rxe2 Qd8 36.Qd6 Rb6 37.Bxc6 Rxc6 38.Re7+ Kf8 39.Rf7+ Kg8 40.Qd5 1-0 Esserman got a very comfortable position early and Sam sacked a pawn for some initiative which was short lived. Match tactics probably explain Black's decision to go for the ending when 27...Qa5 was very strong. The c3 pawn goes as in the game but the Queens stay on.

There Larry felt 15...Be6 16.hxg6 Qa5 17.a3 Nc6! 18.gxf7+ Kxf7 18.d5 Rxb2!! 19.dxe6+ Kg8! was the critical line with one variation continuing 20.dxe6+ Kg8 21.Kxb2 Rb8 22.Kc2 Qxa3 23.Rg1+ Kh7 24.Rb1 Nb4+ 25.Rxb4 Rxb4 winning but of course today the silicon oracles spoil all the fun with 26.Bxc4! as 26...Rxc4 is met by 27.e5 and while 26...Rb2+ wins the Queen White has too much material for it. 16.Bxc4 Be6 Black could have traded on d4 several times and then played ...Qh5 but after Rg1 with Rg5 coming this doesn't look very encouraging and not the sort of position he aims for in this line. What now ensues is a mess and Danya is forced to sacrifice a Rook to create numerous threats. Is it sound? 17.d5 Nxa2+ 18.Bxa2 Rxb2 19.Qxb2 Bxc3 20.Qb3 Bd7 21.Bd2 Bxd2+ 22.Rxd2 c4 23.Qe3 c3 24.Rc2 Qa3+ 25.Kd1 Ba4 26.Bb1 Qb2 27.Qc1 Qb5 28.Ke1 Rb8 29.Kf2 Bxc2 30.Bxc2 Qc4 31.hxg6 fxg6 32.Qg5 Rb2 33.Qxg6+ Kf8 34.Qf5+ 34. Rg1 Rxc2+ 35.Ke3 Qe2+ 36.Kf4 Qh2+ 37.Rg3 Qxh4+ 38.Ke3 was winning but by now both players were practically down to playing on the increment. 34...
