this looks like a piece for 3 pawns rather than 2?

I don't see a good move here myself.  Crafty plays Bb1, but the score is -1.19:

               10     1:20  -1.19   1. Bb1 Bb4 2. Nfd2 f5 3. Nf6+ Kf7 4.
                                    g5 axb2 5. Rxa5 Bxa5 6. Re5 hxg5 7.
                                    hxg5 Bc6
               10->   1:20  -1.19   1. Bb1 Bb4 2. Nfd2 f5 3. Nf6+ Kf7 4.
                                    g5 axb2 5. Rxa5 Bxa5 6. Re5 hxg5 7.
                                    hxg5 Bc6

Crafty likes Rxd3 here.  After f3 it likes d4 for white and doesn't sense any
strong danger at fairly quick depths. but at depth=13 it sees losing the g pawn
to get the queen/bishop over to the kingside.  At depth 14, it gets worse, but
I don't know that it would play f3 in any reasonable time control because Rd3
wins a pawn instantly at +1.x, while this is all positional king-side disruption
that takes longer to see...:
