Black has a decisive advantage.

Softening up the g6-pawn (and the black kingside as a whole) for a later attack.

Heading for f4 in order to attack the weak points at g6 and e6.

A new piece joins the attack.

Black resigned.

Softening up the f5-square for the knight.

2.h3?! Ra3! 3.Bc3 hxg4 4.hxg4 Ng6 Black is clearly better – Lputian. In effect White has to look out for both 5...Nxf4 and 5...Qh4.

Preparing ...Qa8 in order to enter on the a-file.

Despite the minus pawn Black enjoys a clear initiative and went on to win.
