A typical null move trap. F7 with selectivity 0(!), 128 MB hash and 500 MHz announces after Bc7 that black will be mated in 11 moves. As it needs roughly 3 min for this insight I'd expect it to solve the original problem in under 30 minutes. I assume F7 doesn't switch off null move in endgames with queens as it expects the queen to have enough moves to avoid zugzwang (obligation to move). This is seemingly an optimistic heuristic.
