Engine Updates
Michel Van den Bergh builds
GNUchess 5.07.8b MVdB (WB)
Win32 exe with C source; look for Jim Ablett to make a build soon
- Crude LMR implementation. It seems to increase the strength of GNUChess somewhat
- Fix of IsLegalMove{}. Sometimes it happened a pawn got stuck on the 8th rank (this was related to killer moves)
- Fix of st command
- Do node counting at beginning of search. This is easier
- Also: previously there was a bug which made GNUChess count many nodes twice. As a result the reported nps was too high by a factor of almost two
- Help string for sd command was mangled.
