GNU Chess

Michel van den Bergh posted a new release of GNU Chess (5 branch). To test the Android binary, I ran a one-second-per-move, 32MB hash tournament on a Nexus S, using the Silver Opening Suite, with Gaviota tablebases on SD. Below are the results. Although the latest release was mainly for FRC support, it also seems slightly stronger.
