1...Qa6 2.Qxa6 Bxa6 3.Rc7 h6 was preferable. White has still managed to seize the seventh rank, but he doesn't win a pawn as in the game.

In order to parry the threat of 4 Ng5, Black has to give up a pawn.

With the threat 8 Nhxg6; while 7...Kf6 fails to 8.Nd7+ .
White soon won.

Intending 2...Ne4, followed by 3...Rh6, with a kingside attack.

In order to meet Qh4 by 6.Qg3.

Heading for h5.

Exposing the major pieces to a fork. 8.Nd2!? , intending Rfd1 and Nf1, seems preferable.

With the double idea of 11...Nd5 and Nf5-h4.

The last chance was 12.Nxe3 Bxh3 13.Bf3

White resigned in view of 13.Bxd5 Bxd5 with the double threat of 14...Rxe3 and 14...Rg6+.
