If you count the material at the end of the combination, it is Q+4p vs R+B+5p.
Black is probably lost because of his piece position, but it is not crushing(and
also not something a computer evaluates well).
cxb5 wins a pawn and threatens to create another passed pawn. For what it's
worth, here is crafty's evaluation.
17-> 179:51 2.98 1. cxb5 Bb7 2. Rdd1 f3 3. Kf2 Rc8 4.
Ba4 Kd8 5. Rd2 c4 6. b6 Bc6 7. Re7
