King's Indian Defence Bayonet

Attacking and defending require separate skills. You must attack to win. Experts know this. You must defend when good players attack your position. In my early days I was more comfortable defending. I thought strategy was more important than tactics. Later computers and kid masters proved that the game is 99% tactics. In fact strategy is almost all about preparing and preventing tactical threats.

This game features in the King's Indian Defence. I played the 5.Nf3 variation against my postal expert opponent Robert Ash. We were young and gradually working our way up through the ranks. Within a year my rating would go over 2000.

In 1978 the Bayonet Attack was considered speculative after 9.b4!? Almost everyone played 9.Ne1 with an occasional 9.Nd2. Grandmaster Mark Taimanov was one of the early proponents of 9.b4 in the 1950s and 1960s. Others who frequently adopted this line were grandmaster theoreticians Gligoric and Pachman.

I played it well. My middlegame advantage grew until I reached a winning position. Black kept attacking. I defended well until about move 30. Black wore me down with his repeated assaults. I kept choosing second defenses. Then I missed the saving resource.
