Welcome to Lesson 28 of Chess Summer School. We are entering our 10th week and 4th lesson on attacking the castled king. This week, we are looking at some elements of how to attack when the castled position has a pawn on g6. This lesson is particularly instructive because it teaches that sometimes you have to strike when the iron is hot. All that's holding the black position together in the N on f6. What to do about it is not so obvious. This is from an actual game, Hort-R.Byrne, Varna Olympiad, 1962.
1.Nxc6! If White had castled, which many would have done, then Rg8 would have held for Black. 1.g5 Nh5 2.Rxh5 gxh5 3.Nxc6 Nxc6 4.Nd5 Rg8 5.Nf6 Rg7 and Black wins! 1...Nxc6 1...Nxd3+ The game went 2.Kd2 and Black resigned. 2.Nd5 Now it becomes clear. He attacks the crucial defender of h7.1–0
