Black resigned.

Withdrawing the king from the vulnerable g1-a7 diagonal and covering the e1-square.

1...Bxf2 2.Rd7 Re1+ 3.Kxf2 Re2+ 4.Kf3 +-

White is winning.

Removing the king from the vulnerable a2-g8 diagonal in advance.

2.Ng3 Qd1+ 3.Qxd1 Rxd1+ 4.Kf2 Nb3 yields Black considerable counterplay.

Thanks to the clever 1...Kf8 Black is not in check at this point and can continue with active measures.

With an active queen Black has no problems.
