Again. Sorry Ernst! It was you, that wrote the article. I read the article and the pseudocode, but too shallow. I think, I interpreted much wrong. You are right, returning alpha-1 is nonsense. Second: I must include the Mat-win of my move. Third: I must think about extd_futil_margin depending on my program. But one thing was good. There where some interesting post of you and Ed, and thats worth much!!! Werner
