>Both a positional and tactical test. Does any engine find Karpov's 19.Rd3! > Shredder 8 with 32Mb RAM using an Athlon 1800+ finds it in 48 seconds (depth 13) in INFINITE search, and suddendly the score raises from +0.03 to +0.62 and sticks to it. It is hard to tell how much is Shredder "understanding" in this position, but after forcing Shredder to make this move, the evaluation (always given for white) from the black's point of view changes to +0.87 within 1 second, and later to +1.49 (depth 15)!! Allow several years for computers to become much faster than now, and surely these positions will be found through "pruned brute force". P.S.- While I was writting this, the score went to +2.12 still at depth 15, then probably failed high for the search window, and after a research it gave a +0.76, and later a +0.86 for depth 16.
