It is one chess playing unit, and does not matter whether it is built of only an engine, engine + interface, or an interface with a built-in engine... There is no border line between an engine and an interface. For example, in WinBoard the engine is solely responsible for the draw claim, but in the UCI protocol the interface is mainly responsible for claiming the draw. And even though I believe that most UCI users will start printing draw claim info strings from the next WCCC (I have already added this), I don't think anyone did that in Graz. So, the discussion should be focused on whether the operator can overrule his program. The engine/interface discussion doesn't make much sense here. >-- >GCP
