Qb7+ Ke6 21. f4 Rhg8 22. f5 1-0 A game between Nimzo2000 and Hiarcs7, in tourmanent level,in K6-400. It was placed here, in the CCC, for Marcus Kaestner. I am interested in two positions of this game, below I place those positions with some tests and comments. The tests had been made in a PII-300, HT=32Mb(HT=40Mb for Rebel10.0c and System Tiger), with 270(180*1.5) seconds for each move. First Position: 15....? r3k2r/pp3ppp/5n2/1qppN3/8/2PQP3/PP3PPP/R3K2R b - - In this position Fritz versions 1.2, 3.1, 4.01 and 5.00 , Crafty16.6 and CometB00, as Fritz5.32 engines, Fritz5.32, Rebel10.c, System Tiger and Genius6, don't play 15....Qxb2?!, that was played by Hiarcs7. Second position:16....? r3k2r/pp3ppp/5n2/2ppN3/8/2PQP3/Pq3PPP/1R2K2R b - - Here, Fritz5.32, Rebel10.0c, System Tiger and Genius6, play 16....c4, the only move to continue the game. Hiarcs7 plays 16....Qa3? I know that a game is very little to arrive at some conclusion, but it's curious to observe as a strong program as Hiarcs7, considered positional, commits first an positional error (15....Qxb2?!) and soon to follow, plays a bad move (16....Qa3?).
