What did DT play here? I only find Nb5 and I find it instantly and stick
with it... score =+1.5 so apparently DT was winning here. Did it lose by
playing something else???

I get Rf3 instantly here with a draw score. Score 0.00 from the 1 second
mark on. Did DT play Re5? I could see where it might miss the draw since
it had a repetition flaw...

This one is harder (for me/crafty). Crafty likes Nxc7 for a good while.
I ran these on a quad 550 and after 1:44, finishing depth=12, it had not
changed... I might run this longer later tonite...

What does this matter? Black is dead lost already it seems. My score starts
out at +1.5, goes to +2.7 within seconds... Thru depth=11, score is +2.77 for
g6. g6 fails low to +3.5 at depth=12, Kg8 becomes best with a score of +2.81.
I hardly see the difference between the two moves and it looks hopeless
already...
