Thanks to everyone for the congratulations and wishes. The full Rybka team in Paderborn was: operator: Ernst Walet opening book: Djordje Vidanovic engine: Vasik Rajlich I hope that everyone enjoyed the tournament, there were certainly some exciting games. Vas ps. Here are some brief comments from my point of view: Rd 1, Rybka-Jonny 1-0 Very difficult position for Jonny right from the opening, a routine king attack with the pieces by white. Rd 2, Spike-Rybka 1-0 Rybka sacrificed a pawn for dynamic compensation. After some further analysis (see post by Mike Drexel on this forum), my conclusion is that the sacrifice was correct and should give equality up to move 30 or so. However, Rybka misplayed this position (keeping the tension for too long), and was properly ground down in the endgame. Rd 3, Rybka-Shredder 1/2-1/2 Fantastic dynamic game by Shredder in the early middlegame. This is the sort of position where Shredder has for the past few years been the king, mostly I think because of his search. The endgame had chances only for black, but I suspect white can survive it - and in fact this is what happened. Rd 4, Zappa-Rybka 0-1 Playing against Zappa it is essential to get the right kind of position, even more so than playing against Shredder. Like Stefan, but even more so, Anthony has made his big investment on the search front. A solid position with a blockaded center arose where Rybka could simply and systematically play on the queenside. Unlike Rybka-Shredder the search was not a big factor here. Rd 5, Rybka-Argonaut 1-0 Suspicious opening by black and a quick loss of material. Rd 6, Rybka-Gandalf 1-0 Black reacted badly right in the opening (.. c5?) and was forced to accept a lost endgame. Rd 7, Ikarus-Rybka 0-1 Same pattern as Spike-Rybka. Rybka sacrificed two pawns for dynamic compensation. Without any deep analysis, my first impression is that the first sacrifice was correct but the second was not, an impression with which Rybka also agrees after a few more moves. Ikarus opted for a complex, double-edged endgame with chances for both sides. It will take a lot of analysis to figure out where exactly the fatal mistake(s) came.
