Then it's up to the GUI (the user) to handle it as >desired. In "pure" UCI the engine doesn't know (and doesn't need to know) that it is playing a game. The engine just gets positions to search. Actually the engine doesn't know what a game of chess is. Because of this the engine can't resign a game or offer draws in a game. Now we have added the "AnalyseMode" command, so the engine does at least know whether the positon to search belongs to a game or is just an analysis. Also with "ucinewgame" the engine knows to which "game" (actually it need not be a game for the engine, just that after ucinewgame the engine is searching on something different) a position belongs. We did this because of public demand and not because we really liked it. Those two changes are a step in the direction to explain the engine what a game is. If you want the engine to resign something you have to tell the engine what to resign. We didn't want to go that far. It is just a design or philosophical decision. Stefan
