It's a very interesting position indeed but like Uri, I find Shredder's evaluation inaccurate. CM8000B(personality), on my 400 Mhz, takes 2:20 to realize Rxa7 is a mistake by evaluating the position as -0.77. But it takes it 5:18 for it to choose a different move, Kh1, which is evaluated at 0.43. I left CM8000B to analyze for ten minutes and it gave me this. 10:00 1/11 39269040 0.45 d6 Rxd6 h4 Rd2 Qc6 a6 Rxa6 f4 Qc4+ Qf7 Kind Regards, Eric
