I let my AMD Athlon 800 MHz play itself Using GT II  at 5 Minutes per move and
I stopped the computer after this move, since Black has an evaluation of 4.82
which is sufficient to win, plus it was going to force the exchange sooner or
later of the remaining white's knight. But As I mentioned earlier, it is Ed
Panek computer that is playing which is much faster.
