Winning combo for white?

An interesting idea is 1.Re6. This threatens 2.Rxb6 because the c-pawn is pinned to the Queen, and the Rook is immune on the first move for the same reason. It also threatens 2.Rxe6 or 2.Bxe6+. I can't find a better option for Black than 1...Nd5 2.Bxd5 exd5 3.Rxd5 Rxd5 4.Qxd5+, where White won another pawn and seems to have a good position.
