Mine certainly isn't. I don't remember the >details, but I am fairly sure 'usermove' is not the only version 2 feature >my engine requires in order to work. Well, I made the adapter to send 'usermove ' in front of a move just for a test and I played a few games against your engine. Except for me beating him on time all looked ok (the time issue probably is because I use "time" and "otim" to tell the engine how much time is left on its clock, and those are not used in version 2, so I guess your engine just ignores that) > >My guess is that most old engines are compatible with protocol version 1, >but that many (most?) new engine developers don't bother to support anything >except version 2. > >>I'll try some workaround to make your engine run under my adapter .... > >That's not really important.

The thought is that if I make if work with your engine then there is a fair chance it will work for other engines. >But because my engine >is probably not the only one which will cause problems, I think it >is a good idea to try to support protocol version 2 in your adapter. On the long term : definitely a plan ! But I had to start somewhere, and protocol 1 was the logical choice. Andrei
