Hello,

Might be a good idea :P  Maybe there is a "space saver" option :)

I think "Don't choke" is more appropriate :P

That's brutal.. mine is doing a few hundred games / second..

Hrm.. I call my movegen inside of move generation too.. I don't think this is
your problem - even if I were to call my movegen 10 times/move, it'd still be a
lot faster than what you're getting..  maybe I'll have a peek at your book code
and see if anything funky is immediately obvious.. :P

Hmm .. you were mentioning to me that you thought my scheme looked okay except
for the collisions .. well, I'll look into the possibility of doing some
collision resolution later today ;)

I will certainly take a look at it then :)
