Some engines do not immediately (even when given a good portion amount of time) recognize Bxb2 leads ot c1 Bishop being trapped.

After the exchange, d3 is clearly the better move though difficult for some engines. I wonder how much Elo gain adding such knowledge would produce. Komodo 4 seems to handle Bishops quite well compared to other top program.

No problem in this position for Houdini (I tested 2.0c)...
