Hi Bob, I think a bad autoplayer is better than no autoplayer, don't you think so. In my opinion it is absolutly great that Stefan wrote the winautoplayer and everybody can use it. Don't forget that there are more than 20 programs which are compatible to the auto232-standard. Of course you are right , that the autoplayer 232 (dos-version) has its mistakes but you can use it! Everybody would like to see a better solution, but the "bad" autoplayer works. And there is another very important thing: The Winautoplayer 232 is compatible to the Chess 232-pcchessboard. There are still people who like to play themself against these programs (I do). For me this is even more important that the autoplayercompability. I still do not understand why nobody had the idea to make winboard compatible to the Winautoplayer 232. There would be some more fine possibilities to use the Chess 232-pc-board. I offered you some times allready to make some tests for crafty. If you allready have a version with the winautoplayer which does not work with the tablebases why don't you release it anyway?
