1...Ne7 can be met by 2.Qb6! , forcing a queen exchange and winning one of the pawns at b7 and d6.

In view of the threat 5 Ne4, the rook has to retreat.

Preparing Ng3-f5. White is clearly better.

1...h6 has the simple idea of 2.f4?? g6 , trapping the queen. White is left without a natural plan.

Destroying the enemy queenside.

With the double idea of 6...Rxc5 and 6...d3 followed by ...Qd4. Black went on to win.

Securing the king from a check on f7 before getting on with his own attack.
1...Nf3+? 2.Bxf3 exf3 3.Qxf7+-
1...Rf8 2.Qd5! Nf3+ 3.Bxf3 exf3 4.Qg5+-

2.f4 exf3 3.Bxf3 Nxf3+ 4.Kf2 Nd2! -+

Intending ...Rac8-c6-g6 with a strong attack.
