Of course if now Bxd5 white has got away with it ...

but this seems to do the trick. The attack on the rook forces white's hand. Nevertheless stockfish gives Rhe8 as overwhelming based on the pin on the efile and Nb4 is again, well down the list.

and now Nd5 is forced but drops the second pawn after B takes, pawn takes, rook takes. Blacks rooks can take up positions on the d and e files, and he will shepherd the queenside pawns through for victory. White resigned.
