My current testversion Pro Deo 1.1 Vulcan Q1d8c sees a good eval for Bh7 after 2
seconds but not yet any forced mate after 1..Na2. TB's may make a difference,
certainly six piece tables will show it, but Pro Deo does not have TBs. I see it
is a mate in 17? Probably to deep for most programs, as that is 33 plies..
