Huh? That's quick!   However, I would be even more impressed if I would see that
it found 14....Rh1 or 15....Rh1  from the same position in a short time.
Could you test it for that?
And what kind of AMD and Mhz are you using?


[Later, I would be staggeringly fascinated to know if your computer EVER arrives
at the (possibly best moves) of 10...Ng4 and/or 11...h5. If so, I might even
propose that computers have almost solved chess!]

Thanks!
