In the 5th round Shredder had a very tough ending vs Gandalf. Stefan's program showed qualities a là Capablanca. Let's have a look at it after 70 moves. Shredder is white. [D]4r2k/3R3P/8/8/6K1/2p5/2Bp4/8 b - - 0 70 Here Shredder has just played 70.Rd7. Black has two passers for the bishop. White cannot trade rooks since he has the "wrong" bishop. The general opinion here was that it "must" be a draw. But Shredder slowly improved its position. White can create mate threats on the 8th, but has to keep an eye on stalemate themes. We jump to move 87. [D]5r1k/7P/3R3K/8/8/1Bp5/3p4/8 b - - 0 87 Shredder's last move was 87.Bb3. Now black cannot sit still with 87.-Rc8 because of the threat 88.Rg6. Instead he has to buy some time and Luft by giving up one of his pawns. Gandalf played 87.-d1Q. We jump to move 102. [D]5r1k/7P/7K/5B2/8/2R5/8/8 b - - 0 102 In this position Shredder has just played 102.Bf5. Both the black pawns are gone, but white still has some technical problems due to possible stalemate. If now 102.-Rb8 103.Kg6 Rb6+, white has 104.Kg5 Rb8 105.Be6! Instead Gandalf chose 102.-Rd8 and Shredder played 103.Bd7! Re8 (yes) 104.Kg6 with mate announcement. The final position: [D]4r2k/3B3P/6K1/8/8/2R5/8/8 b - - 0 104 Here Gandalf resigned. White has tricks by giving up the pawn and mate. An impressive performance! Sune
