2 …Ne4 (2 … g6? 3 Rxe7! Nxe7 4 Rxf6 +-) 3 Nxe4 dxe4 4 Qxe4 g6 5Qh4 +-

Black got play with 1 … Nf4!. White can’t accept the pawn because 2 Nxf4 exf4 threatens … Bxc3 (and 3 Kb2? Na4+! 4 bxa4? Qb4+ is death).

2 h5! Nxh5

2 … gxh5 would allow 3 Bxf4! exf4 4 Rhg1! and Rxg7+ with an attack.

Threatening Nf6+. A fighting draw followed:

1.h7?? A fatal blunder that costs White the game.

Instead, he should have played: 1.Kd2! Rh3 2.h7 with an easy draw.

1...Be8! Heading for g6 to seize the b1-h7 diagonal.

The bishop is installed on a protected square. Black has no problems.

1.c4!
Clearing the long diagonal for the bishop, where there is no black counterpart.

In order to soften up Black's kingside.
