I could not find the download on your web page nor in the Winboard forum.

This will make Schoolbook 2010 a lot easier to implement.

Sam, your idea of having WinBoard force moves into an engine that refuses them by loading the engine with the position after the move works really great. I implemented in WinBoard now, under control of the option -forceIllegalMoves. In combenation with -testLegality false, this now allows me to completely autmatically play a Schoolbook-Chess match between ChessV and Fairy-Max. Now and then (about 10% of the games ChessV plays a non-standard castling, which then shows up in the PGN as Kf1h1 or Kf1b1, and Fairy-Max is simply restarted. It was a bit of a pain to implement it, because initially the engine will still think the opposite side is to move, and the WinBoard-protocol edit command (which Fairy-Max uses) does not alter that, and the commands that do are deprecated, so the side-to-move has to be flipped by playng a dummy move. But that works smoothly now.

In reaction to some earlier remark you made: there was no reason for hacking WinBoard to suppress the popup after a match: there is a command-line option that controls it (-popupExitMessage false/true), which is remembered in the WinBoard settings file. I use PSWBTM to play the match, in stead of the scripts you use, and this uses that option automaticaly.
