game 1: In this position R7/3r2k1/4b1p1/P2N3p/5P1P/3K1BP1/5b2/8 w - - 0 1 Deep Fritz played 56.Kc4 0.47/15 Rc7 57.Kb4 0.28/16 Rd7 and the following position happened [D]R7/3r2k1/4b1p1/P2N3p/1K3P1P/5BP1/5b2/8 w - - 0 1 Deep Fritz played 58.Nb6 0.09/16 time when it pondered 8:57 and used 1007 knodes per second. I believe that it is a mistake in the time allocation of Deep Fritz. It should use more time for 58.Nb6 and the time of pondering was not enough. The following facts are obvious: 1)Deep Fritz had a possible move that force repetition(58.Kc4) 2)The score of Deep Fritz dropped and was only slightly above 0 I believe that programs should use more time in these situations. The time control was 40/90 and it means that Deep Fritz probably had more than 45 minutes to calculate and in this situation that is not common I would prefer to use at least half of them. After Rd3 it played 59.Bc6 and the score dropped to -0.06 and after the expected move Rb3+ the score dropped again to -0.53 game 3: [D]8/q3kp2/3p1p2/r3pP2/1p2P1PP/8/P1PQNb1R/1K6 w - - 0 1 It seems that Nc1 is the only move for white not to lose material Deep Fritz played Qxb4 with 0.00 evaluation(it used 163 seconds and searahed 906 knodes per second). Only after Rxa2 the score dropped to -0.34 How much time do chess programs need to find Nc1? Does it save white? Uri
