I'm trying to understand what you are saying. If a point is illegal for black, are you saying that black can never play at that point, or are you saying white can never play there? Or are you saying neither side can?
What is the reason for this? I'm not sure I understand what you are saying. Once I tried something I hoped would speed up play-outs a lot without hurting the quality. I considered all "large" captured points as out of play. For instance if white captures a 10 stone group, it becomes permanently owned by white and neither side can move there again. The assumption is that if you capture a large group, you will more than likely be able to hold that space down. I tried a few variations of this, but these things only hurt the program. I think with more analysis you might be able to find shortcuts - one example is the mercy rule which leans on certain assumptions. - Don Harri Salakoski wrote: >>> Hmm, sorry if this is old subject but does it effect much for playout >>> quality if I cut playouts for example max 110 moves in 9*9 board? >> Yes, that will significantly hurt your play-outs.
