Subject: WAC 230 and Alexander Szabo's refutation revisted

Author: Dann Corbit

Date: 12:27:44 08/01/05


Having way too much time on my hands as usual, I thought I would revisit Alex
Szabo's refutation of WAC 230.  Some strange things happened with 10 hours of
analysis using 500 MB hash on 2.2 GHz AMD 64 bit machine:

"Win at Chess" #230 main line (after 1... Rxb4) according to Alexander Szabo:

2. cxb4 a4 3. b5+ Kxb5 4. Ba3 c3 5. Re2! Kc4 6. f4 Kxd4 7. f5 exf5
8. e6 Kd3 9. e7 Bd7 10. Kf3 d4 11. Rh2 Kc4 12. Rh8 b2 13. Rb8 d3
14. Bxb2 cxb2 15. Rxb2 a3 16. Rb7 Be8 17. Ra7 Kb3 18. Ke3 a2
19. Kxd3 Kb2 20. Rb7+ Kc1 21. Ra7 =

The key move for white to hold the game is Re2 with the plan of tying
down the black bishop by generating a passed e (or g) pawn."

We pick the board position up at move 5 (all tested engines agree to that point
anyway):
[D]2b5/8/4p1p1/1k1pP1P1/p2P4/Bpp3K1/1R3P2/8 w - - bm Re2; id "WAC.230 after Rb4
cxb4 a4 b5+ Kxb5 Ba3 c3";

Shredder 9 gets stuck on ply 27 (after about 3 minutes) with either a massive
fail high or fail low [or a bug], and does not say a peep for ten solid hours:

Fruit's output most closely resembles that of Alex Szabo, and also most closely
mirrors his drawish score:
