If I captured their pawn with my queen, would it be a draw, or would they have a win? As I would run out of time, that is for sure.
Checkmate is possible with a king, bishop and knight against a bare king, and therefore it would have been a win for white if you timed out before the 50 or 75 move rules came into play. So for instance if the game had gone 72 ... Qxh3 73 Bxg3 and then you timed out within the next 50 moves it would be a win for white.
