Winboard Forum

I've been having a weird problem with AICE under arena. First some notes:

- works fine as winboard engine
- works fine when I play it (as a human)

But it gets in a funny state when in UCI mode against other engines. Here's an example where AICE moved first, FireFly replied, then AICE started thinking (for wrong side) even before receiving the "go" command.

Any ideas what's going on? Sorry if this is a known issue...

Hi Michael,
it is a bug in AICE. When AICE receives the 'isready' command for a second it starts to think. I'll fixed soon. My Arena (1.1) or Fritz8 does not send 'isready' for second time. Thanks for point it!

Thanks for looking into it! -- Michael
