At that point CM8K sniffed the move for 1:49, and after that, moved it to 5th for the next iteration. But alas, after an hour and 10 minutes it was passed over once again. So many moves; so little time! Steve Time Depth Score Positions Moves 0:00 2/6 0.73 33774 1. Re2-e3 f7-f6 2. g2-g3 Kd7-c7 3. Nf4-e6+ Kc7-b8 4. Re3-c3 0:01 3/7 0.86 146773 1. c5xd6 f7-f6 2.
