Position after 73...Nd6 -- now it is Crafty showing +5.01 lead, GT shows it is
down 1.62 - but that quickly changes to -3.21 on the next move. The game is
over at this point. It appears that GT avoided the perpetual check around move
59 and thus lost the game. I did not understand the move 63... b5 , as there
appeared to be inadequate compensation for just throwing the pawn away.

took Crafty 9 seconds to see this move on my machine.
