Note this Newsletter is going out early as John Donaldson will be playing in the 5-day schedule at the World Open. Alex Yermolinsky is playing in the 7-day schedule so there will be no lectures this Tuesday and Wednesday.

1) Mezentsev wins 3rd William Addison G/45

SM Vladimir Mezentsev (2522) won the 3rd Annual William Addison G/45 held June 28 at the Mechanics' Institute. Mezentsev scored 4.5 from 5, drawing with up-and-coming Expert Nicolas Yap in round 3 and defeating NM Emmanuel Perez (2340) in the money game. Tying for second at 4-1 in the 47-player field were NMs Perez, Ron Cusi, Michael Pendergast, plus Expert John Glass and A-player George Sanguinetti. Anthony Corrales directed for the M.I.

2) Pruess leads in Montreal

Recent UC Berkeley grad David Pruess is off to a rocket start in a Category 3 (2304) round robin being held in Montreal. Pruess has 5 from 5 including wins over the top 3 rated players (number one seed IM Jean Hebert) and needs only 1 1/2 from 4 to make his first IM norm. Go David!

3) Summer Tuesday Night Marathon

The sixth round of the Summer Tuesday Night Marathon will be held this evening. Nicolas Yap leads with 5-0.

The following game was played in round eight of the last Tuesday Night Marathon.

Peter Grey - George Sanguinetti
Tarrasch D34
Spring TNM (8)2003

1.Nf3 d5 2.d4 e6 3.g3 c5 4.Bg2 Nc6 5.0-0 Nf6 6.c4 Be7 7.cxd5 exd5 8.Nc3 0-0 9.Bg5 cxd4 10.Nxd4 h6 11.Be3 Re8 12.Rc1 Bf8 13.Nxc6 bxc6 14.Na4 Qa5?

This very plausible looking move is a serious mistake yet continues to be played today, two decades after San Francisco IM David Strauss first showed its failings. 14...Bd7 is necessary.

On the 31st move Steiner had a full 20 minutes but then thought so long that he only had 10 seconds for the remaining 9 moves.
