11:22 pm - The chess gods love the Blackmar-Diemer Gambit
I got up early Wednesday morning for the Chess Journalists of America annual meeting. I should not have bothered, because the CJA has not changed in the 20 years I've known it, a worthless volunteer organization with the sole function of giving awards for journalism to undeserving people.

Across the playing hall at the US Open, I could see a man wearing a STOUDEMIRE T-shirt. I couldn't make out the number — I walked over to take a closer look.  If it was a Suns shirt with number 32, the guy could be my friend. The number was 1 on a Knicks shirt, meaning the guy is an early adopter of Stoudemire version 2.0. He has no idea how many bugs he'll find in that piece of crap.

Weirdly, there are two guys wearing ugly Yes concert T-shirts. Roger Dean made some great, great album covers for Yes, but when you apply the style — especially the unreadable lettering — to black concert tees, they're just ugly shirts. I asked one of the guys if it was just a coincidence or if they were buddies. "Total coincidence," he said with big grin.

The vagaries of the Swiss System paired me with my previous opponent's sibling. In round one against Janice Chen, I waited until move 25 to sacrifice a black pawn, and won on move 78. Against her brother Tony I had the white pieces, which meant I could sacrifice a pawn right away.

White: Frisco Del Rosario (2095)
Black: Tony X. Chen (1961)
Event: US Open
Date: 2010-08-04

1. e4 d5 2. d4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 Bg4 6. h3 Bxf3 7. Qxf3 c6 8. Be3 e6 9. Bd3 Nbd7 10. O-O Be7 11. Qg3

Diemer has played 11. Rf2 and 11. g4. The rook move is better than my queen move.

11. ... g6

11…0-0 (best, probably) Stummer-Spate, correspondence 1990; 11…Nh5 Muller-Klugert, BGD thematic 1984.

12. Bg5 h6 13. Be3 g5 14. Rae1 Qa5 15. Bd2 O-O-O 16. Nb5 Qb6

16…Qxd2 17. Nxa7 mate.

17. Nd6+ Bxd6 18. Qxd6

The f-file is weak and White has bishops, but the snowball is not yet rolling.

18. ... Ne8 19. Qa3

Now White's in business. Rxf7, Ba5, and Be3 are all in the air.

19. ... Nef6 20. Kh1 Qxd4

Generally, when Black plays …Qxd4 in the Blackmar-Diemer, it is either a winning move because White's position is falling apart or a losing move because White gains more time chasing the queen.

21. Be3 Qh4 22. Bf2 Qh5 23. Qxa7 g4 24. Bg3 e5 25. Rxf6

Bang. White's main threat is 26. Rxc6+.

25. ... Nxf6 26. Rxe5 1-0

Trapping the queen is secondary to 27. Re7, forcing mate.
