Tinman - winboard Chess Engine Rating JCER=2593 Tinman is a 64-bit computer chess engine developed by Mike Leany. It is a re-write of my old chess engine Vapor into the Rust programming language. As of v0.1.0, it plays about on par with Vapor, despite thinking more slowly and lacking a transposition table. It appears that this is because Tinman has a better evaluation function. New: Added null-move pruning, which gives a significant improvement. Added material draws (and drawish material) to evaluation.
