Probably it is bm Qc1, too . It is not clear. White has some other alternatives Junior5.9 with 5 options considers 1.Qc1 as best but it also considers 1.Nxe6,1.a4,1.h8Q,1.Bf6 as winning moves The scores are: 1.Qc1 15.20/13,15.23/14,15.53/15 1.Nxe6 13.19/13,13.29/14,12.98/15 1.h8Q 13.09/13,13.09/14,13.09/15 1.a4 12.38/13,12.68/14,12.62/15 1.Bf6 11.16/13,12.38/14,12.98/15 If I give it 7 options it can find that Rxf5 and Nxe4 are also better than +10 for white.
