4...Ra8 5.Qxd3 Qxd3 6.Rxd3 Be7 7.Re3! +-

Black resigned.

Preparing ...Nc4-d6 with a firm blockade of the passed pawn.

Now Black gets considerable activity.

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.
