Hmm, actually this discussion turned up a bug: by inspecting the code in order to remind me how castlings are encoded, I noticed that they are performed in a way that could be incorrect for some FRC positions: first it clears the king square and puts the king on its destination, then it clears the rook square, and puts the rook on its destination. But the king could have ended up on the square where the rook started, which would give a nice disappearance act.


Well, at least it was just the rook that disappeared. I know from experience that a program can function reasonably well if a piece occasionally vanishes. But, let the king disappear and you have total havoc.

Best
