Re: Engines playing Musketeer Chess, good price

The WinBoard-AA package now contains a WinBoard version that no longer needs a gating suffix to the move in holdingless Seirawan.

Nevermind I fed stockfish the wrong FEN -- I did not understand the musketeer placement format. I should be able to debug my perft now using stockfish.

Re: Engines playing Musketeer Chess, good price

@Ferd I get the first perft all correct. Ok good. The second one is wrong after and including perft(3) That position is complicated not sure if mine is even correct. If we don't agree at perft 3, here is the perft divide at 3. Can be of help to track down the issue. Perft divide 3 a2a3 : 1326 a2a4 ...
