Thanks, Peter, yes seems a1=Q (as well all other conversions) Bxa1 is unavoidable.

Hi Frank,

Ran this through from original position with latest Brainfish 271218. Move 4 looks to be an arbitrary decision as to whether to play 4.Be5 or 4.R8g3 when the engine score confirms a win for White when it becomes just an academic exercise for which move is best if precision is required. After 4.R8g3 I stopped Brainfish at 49 ply with a score of 14.29 to White's favour after 12 iterations at 49 ply with the score increasing on each iteration. It did not seem to want to move on to 50 ply! The engine analysis is included in the game annotation below.
