King's Indian Killer: The Harry Attack

Do you want a simple and practical method to counter Black’s kingside fianchetto defences after 1 d4? A line that takes the initiative from a very early stage and creates difficult practical problems? If so, then The Harry Attack (1 d4 Nf6 2 c4 g6 3 h4!) is for you.

At first this looks like some sort of joke or, at the very least, a weird outlandish line. Aren’t we all taught to focus on development and control of the centre in the early stages? What’s 3 h4 got to do with that?

Perhaps surprisingly, this is a very difficult line for Black to counter effectively. This applies not just in practical play but also theoretically, where it is far from straightforward for Black even to find a route to equality. And when Black gets it wrong they are often on the receiving end of a very unpleasant miniature.

You may be thinking that surely the best chess engines can show how to counter this line? No! One of the unexpected features of leading engine play is their enthusiasm for shoving the h-pawn up the board and they fully concur that 3 h4! is a very decent move for White. Many leading players have taken the hint and 3 h4 is frequently seen at elite level.

Richard Palliser and Simon Williams (the GingerGM) provide a thorough guide to this fascinating line. They show how to adapt when Black chooses a King’s Indian set-up, a Grünfeld set-up, a Benoni set-up or even plays in Benko style.

The Harry Attack is easy to learn and is perfect for unsettling players steeped in the theory of their favourite Indian defences.
