Absolutely astonishing! Both players played like computers for nearly all the end sequence. In each case, the player made the exact choice predicted by crafty. This sequence begins quite a ways in, but well before the (apparent) death blow. Yet each move was optimal, or nearly so. r2qr1k1/1p4pp/4bb2/1P1PNp2/pB2pP2/8/P3Q1PP/2RR2K1 b - - acd 16; acn 626145589; acs 1000; ce -30; pv Rc8 Rxc8 Bxc8 d6 Bd7 Ba5 Qc8 Nxd7 Qxd7 Qc4+ Kf8 Bb6 a3 Qc7 Rd8 Bc5 Bb2 b6;

Notice how incredibly long the two players followed the suggested moves by crafty. In fact, if I saw this game without authors and used crafty to analyze it, I would imagine that crafty played both sides! Really, a remarkable and fairly forced long sequence. I wonder when Shirov knew that he had it? Was it early-early on? Fascinating.
