ChessV 0.9.0 is available here:
The source for 0.9.0 is the 'ChessV_Source_0_9.zip' file
Maybe ChessV 0.9.2 will play better than 0.9.0 with your fixes, though. Let me know when a download is available.
OK, thanks for this info. But where can this 0.9.0 version be obtained? 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...
Muller: Using the ChessV 0.9.0 instead of the ChessV 0.9.2 codebase might fix the bug with it changing sides in some positions, usually lost (well, in ChessV's GUI it just moves some pieces around).
ChessV 0.9.0, IMHO, was more bug-free than ChessV 0.9.2, and I feel it was Strong's best release of ChessV.
OK, I finished the conversion of ChessV. The same URL now contains the finished version. This is a 'Release' compile, i.e. there is no debug code in there that slows it down anymore, and it reaches reasonable depth (similr to Fairy-Max). It should handle promotions automatically. (In so far the promotion piece is indicated in the input move by the first letter of the name under which ChessV knows it, except for Knight, which must be indicated by 'n'.) This WinBoard version of ChessV supports both conventional and incremental time control. Unfortunately it still has the same bug as the normal ChessV: in complex positions it sometimes switches to playing the other side...
