I am not an expert but I ran the move against CM6000 and Fritz 5.32 and they both gobbled up the rook and then went on to lose the game 25Rb6 NxR 26 PxN Bxf4 27PxQ Bxe3+ 28Kf1 BxR 29Qc6 and both machines acknowledged a losing game.It would be interesting to see if computers find a defence to Rb6 . regards allan t have to disagree.
