.. I just played out a 65 move, 'mate' win, {as, 'white'}, in your '960' variant, vs. "Rasputin." -- Considering, that my computer opponent lost a piece, to a simple "pawn fork," on move 11; is it too much to expect to have to play that particular game out, to its 65-move, mated position, conclusion, without being offered a 'draw,' on the last, circa, 30 moves; where "Rasputin" was a piece 'down,' the whole time?!
 
.. I seem to recall, that I've played other games, versus your online chess-servers, where they will resign theoretically lost games, at the normal, 'polite' juncture!..
