Re: Engines playing Musketeer Chess, good price

The image is from before the move, so I cannot see whether c1c3f gated the fortress or not. But I guess I should have realized this is not Musketeer960, so that the Rook on c1 is not an original piece. So the shown position is an invalid one, displaying a Fortress that is no longer gateable. The que...

Re: Classes of chess pieces for chess variants

It should not be too difficult to add this or a very similar rule toFairy-Max. I just don't see why you would want R or Q to be able to single-handedly checkmate a King, or why you would want a King to be so defenseless. To me it seems a bad feature. But this apparently is just a matter of taste. I ...

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. WinBoard already had code that made it resistant to missing promotion characters, supplying a default in that case (usually Q). So I just had to make the legality test r...

Re: Engines playing Musketeer Chess, good price

Does xboard (not winboard) have alien mode incorporated correctly? I was trying to play musketeer in alien mode but it only updates the initial position correctly even if nebiyu sends a setup command after each move. I installed xboard a while ago though. Also, I remember xboard does not recognize ...

Re: Classes of chess pieces for chess variants

I have had Fairy-Max play games against itself now without using this rule, but they don't last particularly long. I guess this is because the pieces are so much stronger, especially rooks and queens. KR-K can be won very much faster than in normal chess, because the rook creates its own corner, whe...

Re: Classes of chess pieces for chess variants

Indeed, I did not program the king-in-check rule yet. What is the use of this rule anyway? I tried a few end-games (K+R vs K, K+2B vs K, K+B+N vs K), and Fairy-Max never had much trouble checkmating the bare King in any of those cases.
