Note that there has just been released a WinBoard compatible version of the variant-capable engine Dabbaba of Jens Baek Nielsen. One of the games it knows is Knightmate. You can currently watch it play a Knightmate match live against my own engine Fairy-Max, on my Chess-Live! webserver
http://80.100.28.169/gothic/knightmate.html
for the next one or two days.
If anyone knows any other WinBoard engines that can play Knightmate, let me know; then I could hold a tournament.
