OK, let me enlighten us, I let them play and MCP7.1 won! It is interesting if any other program would win this endgame too?! Anyone testing Junior5, Hiarcs6/7 and CM6000? Here is the whole game, position was reached after black's 100th move: [Event "auto232"] [Site "Recklinghausen"] [Date "1998.12.03"] [Round "39"] [White "M-CHESS 7.1"] [Black "Nimzo 98"] [Result "1-0"] 1. e4 e5 2.
