Yes, I will certainly let you know if I find any improvements. So far, I find the results extremely promising. My second 100-game match is almost finished, and it seems that the version with your extension will win by a similar margin this time, too. It does not happen often that I get such a big improvement with just a few new lines of code. But of course, it remains to be seen whether the extension is effective in matches against other engines, too. Results of self-play matches are often misleading. Tord > >Best wishes, >Sergei
