Re: Shogi Perft numbers

Extracted sfen from Alphazero-elmo game 1 from https://deepmind.com/research/open-source/alphazero-resources where there is a lance or a knight in the on-hand. Then convert the sfen to winboard shogi fen. Run Siyam on 20/123 positions selected randomly to get the perft 1 and 2 counts. Siyam v0.46 pe...

Re: Shogi Perft numbers

Big thanks to Ferdy! Yeah my RubyShogi was full of bugs. Horse moves were buggy. This pawn drop checkmate was wrong. Drops were wrong... Hopefully my numbers are now correct. I can finally start polishing RubyShogi. Random position generator + perft: ruby ruby_shogi.rb -randperft ~~~ randperft( 10 ...
