Uri must have been disappointed with this one. Amateur was favourite in that game thanks to better hardware and being white. I do not know which engine is better. I do not think that Movei play bad at that game and Movei did no stupid blunder. Movei's last mistake was 28...Rxc5 but I found that Movei is not the only program with problems in that position I find that Movei needs depth 13 to fail low on 28...Rxc5. Here is some analysis on p850 of latest Movei(64 Mbytes hash) [D]2r1r1k1/6pp/4p3/B1Pp4/4nq2/3Q3P/PPR1RPP1/6K1 b - - 0 28 12 -85 16022 22409104 c8c5 c2c5 e4c5 d3c2 c5e4 c2c6 g8f7 a5c7 f4f5 a2a3 e4f6 c7e5 f5b1 g1h2 12 -85 31961 44277326 c8c5 c2c5 e4c5 d3c2 c5e4 c2c6 g8f7 a5c7 f4f5 a2a3 e4f6 c7e5 f5b1 g1h2 13 -194 38602 54122796 c8c5 c2c5 e4c5 d3b5 f4f8 a5b4 e8b8 b5c5 b8b4 c5c6 b4c4 c6e6 f8f7 b2b3 c4c1 g1h2 d5d4 13 -193 40326 56632335 e4c5 13 -164 41430 58228606 e4c5 13 -95 44127 62370292 e4c5 d3e3 f4e3 e2e3 d5d4 e3e1 c5d3 c2c8 e8c8 e1d1 c8c1 d1c1 d3c1 a2a3 e6e5 13 -95 78467 108576033 e4c5 d3e3 f4e3 e2e3 d5d4 e3e1 c5d3 c2c8 e8c8 e1d1 c8c1 d1c1 d3c1 a2a3 e6e5 14 -96 137468 191119054 e4c5 d3e3 f4e3 e2e3 d5d4 e3e1 c5d3 c2c8 e8c8 e1e6 c8c1 g1h2 c1c2 e6d6 c2b2 d6d4 d3f2 Note that analysis by yace(only material) suggest that after Nc5 Qb5 black lose a pawn but here black has a positional compensation that Movei seems to evaluate it as slightly more than a pawn so it gives Qe3 in it's pv.
