Hi Everyone A little exchange sacrifice [D]r4rk1/4p2p/p1Nq1bp1/1p1P4/1Pp2P2/3nQ1PB/P5KP/2RR4 w - - the game went 28. Be6+ Kg7 29. Rxd3 cxd3 30. Qxd3 and white later won the game. Im not saying this is a winning exchange sacrifice, but I think its at least equal with good chances for white. Crafty 19.03 sees it quite fast, 0:24 and sticks to it, Shredder 6 Pad. Class. drops at 0 seconds and first sees it again after 5:31 ... Could it be a good positional (test)move ?
