Improvements

  • +65 Elo over 0.9 (200 games, 0.2 s per move); 95% against Stockfish 2800 and 63% against Stockfish 3190.
  • Stronger search: principal-variation lines are searched more carefully, checking moves are reduced too, move history looks four moves back, evaluations are corrected by the last two moves, deeper null-move pruning.
  • Faster network: the output layer works in integers, about a third faster with the same evaluations.
  • Network fine-tuned further on all training positions.
  • Website: a Review page for chess.com, lichess and Blizzard Chess games.
  • The built-in opening book is now off by default (option OwnBook), so the engine plays from your GUI's book.
  • Safer time management when the clock runs low: no losses on time even in long games without increment.
  • Blizzard is now under the MIT license.
