To capture en passant, move your pawn horizontally on top of the pawn
you're capturing.  Chesstool will then automatically place your pawn one
square forward where it really belongs.

I would also like to see a way of increasing the difficulty as well as a
way to set it for rapid play, and to have a better opening book.  I think
I've heard of some kind of GNU chess which is supposed to have a good
opening book.  Anyone using a version that runs under SunView?

At a Sun booth at a conference I played a chess program that was running
on a network of Suns, with several cpus thinking at once.  It was
noticeably stronger than chesstool on my Sun 3/50.
