In problem 006730 The putative solution is B(d7)x B(b5) . If N(c30 x B5) white has

a posted knight because a6Xb5 looses rook a8. Takes more thsn 30 or so seconds to think this all out but I suppose also the position is better than allowing B5xD7KxD7.

I felt it was a little unfair to lose 16 points on. However it seems a position that occurs relatively often so its worth the pain.
