headius: Thank you. Ok, I am also refering to a permanent disagreement between the players about dead stones. What does happen then? Message to Fencer? Consider this situation: I pass, my opponent passes, I mark dead stones, he disagrees. Now the program gives the oportunity to prove the situation and it's my turn. But when I now put a stone it will diminuish my points or am I wrong? Maybe I am also just exaggerating and this one point is not important, don't know. Anyway. Thanks for the answer.
