Which prog needs how long to see that this >is not a draw but black wins? What if White decides to move his King back and forth between g7 and g8, how can Black force the win? I do not see that Black can force a win. For example: 1. ... Rc7+ 2. Kg8 Rc8+ 3. Kg7 Rc7+ 4 Rg8 Rc8+ 5. Kg7 Rc7+ 6. Kg8 draw by 3 fold repetition. or 1. ... Rc7+ 2. Kg8 Rc2 3. h8(Q) Rc8+ 4. Kg7 Rxh8 5. Kxh8 Kf7 6. K moves and White does not need to move any of the pawns. How can Black win then? What is it that I am missing? Regards, Laurence
