White prepares Nc4 in order to break the blockade on d6.

Logical but tactically ill-founded.
A better try is 1...Rd8 2.Nc4 Ra6

Deflecting the bishop.

7...Qxg6 8.Qc8! Qf6 9.Re8+ +-

Black resigned.

A rook sacrifice that produces a dangerous passed pawn.

2...Nf6 3.f3! R3c5?!

3...Bd7 4.a7 R3c5 was preferable, although after 4.b4 Qxa7 5.bxc5 dxc5 6.Qf2 White's advantage is practically decisive – Golubev.

Recovering the rook with a decisive advantage thanks to the passed pawn.

Black resigned.
