Mate in 12. Thanks! This is second confirmation that mate is found by selective in 12 and, probably, there is no mate in 11. My search by brute force took already slightly over one hour to say "no" for 10 moves. Since my branching factor jumped between 9 and 10 move, it could be that mine will need entire night, or even more, to see next 11. You have impressive NPS number, 1696k. Mine was (but on 600Mhz) 595k.
