Bob, As you posted in one of the replies below, Crafty analyzed the ending position in game three of the X3D match, after white’s Rb3, about +2.6, and even before the end that white had a far superior position. Uri, I think it was, posted analysis of other engines and most were +1 or less. Results I got for depth of 12 ply were as follows: Crafty 19.03 - +2.68, Shredder 7.04 - +0.95, Fritz 8 - +0.44, CT14 - +1.24, and for depth of 15 for Junior 7 - +1.05. I think we have to assume that the new deep Fritz running in a 4X2.8 configuration also came up with a similar analyses that it was lost, probably +2.5 or worse. Tony Rook on Chess FM radio said 4-5 moves before the end that Mathias had said Fritz would not resign unless the analysis was that much in favor of GK (white). There was no doubt among the grandmasters that Fritz (black) was toast, with GM John Fedorowicz on Chess FM radio even going so far to wonder whether GK would be getting upset that Fritz was playing on in a completely lost position. Obviously your Crafty was one of the few engines to analyze the position properly. I congratulate you on Crafty’s fine analysis. What do you attribute Crafty’s analysis superiority in this position to compared to the top commercial programs? Thanks. Chris
