I'm glad that it finally worked for you. I have an old Chinese Chess program
"Uncle Wang" that runs under DOS, so I'm still somewhat familiar with that
world. Angel's program is a little bit confusing since it uses the older
terminology, but not too bad. It's too bad that it wants you to specify plies
instead of time - this kind of makes it hard to be fair. It seems that it
searches roughly an order of magnitude slower than Vortex. I don't have enough
x86 computers to do any sort of match.

I'll shut up now about patent stuff.
