Your sample size is small, but I wonder what makes it different for computer-computer games. It would be good if everyone who tests two programs against each other at 40/2 could submit the results to a central area where everyone could download the results. With a larger sample to work with, some trends could be identified that might help the chess program authors to handle their opening books better. I don't mean killer books, but just lines that seem to do well against all computers as black or white. Data from 13700 human games: White wins 34.66% Draws 43.00% Black wins 22.34% This fits in with the general perception that the Queen's Indian is drawish. The main line variation was even more so (5154 games): White 31.67% Drawn 46.71% Black 21.62% I think that SSDF should perhaps require submission of PGNs from all testers to validate the data, and to create data as described above. Thanks for your interesting post, kp
