This is the epd position for move #38. This good be a good positional test.
The trsditional thought on this type of ending is to avoid putting
ones pawns on the same color as the attacking bishop. I think a better choice is
to move the attacked bishop. After that I believe black could win this game.

This makes a nice test position. We know from the game's conclusion that
Bxa3 loses by force. How many programs will play Bxa3? My guess is that
most would have to think for quite awhile before they see that it loses.
