In the version I have posted now I was able to work around the color-switch problem: this seems to occur when there is fail-high in the root. The research then seems to be done with a messed-up move list. By doing the initial search with a fully open window in every iteration, there can never be a fail high, and the problem does no longer occur. In fact it seems ChessV plays a lot stronger by this! I guess that even in the cases where there was no color switch, a re-search would make it do a random move. Major remaining problem is that ChessV seems to be blind for promotions in its search. It takes no measures to stop an enemy promotion, and its score stays positive up to the very moment that the opponent promotes. After that it is of course at -9000... Edit Form You may not post a new comment, because ItemID ChessV WinBoard does not match any item.
