I made it play against my experimental two games (10min 0s inc) and Queen lost both on time around move 30. The first game was a pitty because it was spanking my program. At one point, my program used 2-3 minutes and Queen 8 minutes, quite early in the game. BTW, Time control is really tougher than I thought.
