On 1...Ne6, there follows 2.Rc2! Qc5 (2...Rfd8 3.Ne7+ Kh8 4.Qxh7+ Kxh7 5.Rh2#; 2...Rfe8 3.Rh2+–) 3.Rh2+–.
Black also cannot avoid mate after 2...Qa3 3.Qh6 Qxc1+ 4.Qxc1 Kh8 5.Nd6 Rad8 6.Qh6 Rg8 7.Nxf7#.
In a surprising way, the black army is unable to defend the f7-square and prevent smothered mate.

Black’s position is difficult, but after 50...Rb5!, attacking the pawn on c5, White would still have to show some good technique.
Now, Black suffers further material losses, and loses the game. Although the rook on d4 is in the centre, it is trapped!
51...Ke7 52.Nxe5! Rxd2 53.Nxc6+! (an intermediate check) 53...Ke6 54.Kxd2+–.
