Just do conditional moves or play it, because maybe you missed a move or thought that it wasn't a forced mate when it really was (allowing an unfairly won game).
Jim you are right... and many of us do just that... I do. The reason though I thought about having this option is for those last few games in group play where the game has been decided and is down to a few obvious check mate pattern moves... but the opponent will not resign. Most of us have been a part of very large tournys where all the 50+ groups have finished group play except for one or two and the games are drwan out which adds weeks (or months) for everyone else to move on to the next round.
This is a bad idea. If the conditional move program is taught to detect/find checkmates...people will cheat by using it to find mates, or to improve a line when they can smell a mate but can't find one.
I understand what your saying and thanks for responding. See my previous post where the conditions for this might work.
