v1.3
9864a5b

Roughly 2950 ELO (CCRL)
Regressions vs. 1.2:
+131 in 8000 games at 3+0.02
+128 in 4000 games at 15+0.05

Major changes from 1.2:
Syzygy TB support
Evaluation tuning using a method based on Texel's Tuning Method
LMR at PV nodes
Change LMR formula, create a search stack to provide more information for pruning decisions (ideas from Stockfish)

Three binaries are now provided.

  • Laser-1_3 for 64-bit machines with POPCOUNT support
  • Laser-1_3-NOPOPCNT for 64-bit machines without POPCOUNT
  • Laser-1_3-x86 for 32-bit machines. The 32-bit compile is not optimized very well - this may improve in a future release.

Thanks also to Michael Byrne for providing a Mac compile: https://www.dropbox.com/s/w1juxbhxpzjyr84/uci-chess-engine-1.3.zip
