Hello Matthias, when using the UCI protocol, Arena expects O-O when in FRC-mode and e8g8 when in normal mode. So your engine must have an option to distinguish between normal chess and Chess960. UCI_Chess960 is a good choice ;-) When you want to support both, Arena and Shredder, you can do the following: When UCI_Chess960 is false, send e1g1, else if last FEN string was XFEN, send O-O else send king captures rook. That's ugly, but it works for Hermann (private versions from 1.5.3 on) and it should also work with future versions of Arena, whatever Martin Blume will implement. Greetings, Volker
