Hi,
Ikarus switches from 1. Qc5 to 1. g5 (hxg5 2. Qc5) after 5 seconds (P4-2.4GHz,
64MB Hash, 5-piece TB) and announces mate in 32 soon after.
However, after about 3.5 minutes, it switches back to 1. Qc5 with mate in 24, so
your position does not have a unique winning move.
But the draw agreement was premature in any case...
Best regards - Munjong.
