Black's clever knight regrouping has enabled the idea of a central break with ...e5-e4.

With a strong initiative thanks to the excellent knights. In contrast, the passed pawn on d5 has completely lost its potential.

Opening a new front on the kingside, in order to exhaust the black defence.

1...h5?! 2.Rg3 Kh7 3.Bd3! Nxd3 4.Rxd3 , followed by 5 Nc7, is equally troublesome for Black.

White later realized his extra pawn.

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+ +-
