Hard to say. I definitely have code for opposite bishop positions, and I have
seen crafty play such positions with some degree of 'sense'. But it is hard to
say whether that is "the reason" here... I will look tonight to get an idea of
what it is seeing/avoiding...
In any case, humans exploit such holes all the time if you don't "fill them".
