Same for IsiChess MMX, likes Ba7 too all the time.
I thought i recently had implemented some trapped bishob code ;-)
Or was it already the AMD64 XMM-version which takes some more time?

I guess there is probably wrong king safety compensation for the trapped bishop.
May be the closing "c5" makes the black king safer, due to less levers but more
rams on king related files. Other black pieces and the advanced pawns may be
ready for a king side attack. Interesting position!
