The basic King’s Indian setup sees Black fianchetto their dark-squared bishop, as shown in the position below.
If Black continues with the main line of the King’s Indian Defense, then they will play …Nc6 next. White’s best way of fighting for an advantage is with d5. This pawn advance closes the center and also gains a tempo against Black’s knight. Black will then play …Ne7, and we reach the following position.
This exact position has been reached thousands of times in master-level play! Both sides have played eight moves, and now White has a vital decision to make.
The most popular move is 9. Ne1, with the idea of eventually re-routing the knight to d3 in order to support White’s key c5 advance. This is known as the “Classical Variation” and has been studied extremely extensively. The opening theory runs over 20 moves deep in some lines!
The second most played move for White is 9. b4 - the King’s Indian Bayonet Attack. While the Bayonet Attack is still theoretically demanding, it is relatively less-so than the Classical Variation.
The b4 advance that characterizes the Bayonet Attack has the same idea as the Classical Variation: to support the eventual c5 pawn break. This c5 move is essential for White when playing against the King’s Indian Defense. Black is going to play f5 and attack on the kingside. Therefore, White needs to start their own counterplay on the queenside.
With the battle lines now drawn, let us take a look at some of White’s most important further middlegame ideas in the King’s Indian Bayonet Attack.

Thematic Ideas In The King’s Indian Bayonet Attack
Maneuvers Of The Kingside Knight
One feature of leaving the kingside knight on f3 (instead of shifting it over to the queenside via e1 and d3, as in the Classical Variation) is that it can come to g5 and eventually e6.
Take the following position, where Black has just played their thematic pawn advance …f5.
White now has the option of coming in with their knight to g5. This creates two threats that Black must deal with:
- Bxh5, which would win a pawn and ruin Black’s kingside pawn structure.
- Ne6, which forces Black to give up their important light-squared bishop in order to avoid losing the exchange.
This is very annoying for Black. They cannot afford to allow Bxh5, so must retreat their knight back with …Nf6. But once White’s knight occupies e6, …Bxe6 from Black is essentially forced. Black loses an important attacking piece for their kingside ambitions, while White’s queenside play can continue unabated.
A Well-Timed Nd5
This idea is related to the previous one.
In the below position, White has performed the Ng5 -> Ne6 maneuver mentioned previously. Black has captured the knight with their light-squared bishop, and after White recaptures dxe6, a White pawn is left on e6.
This pawn looks rather overextended and weak. It is very tempting for Black to attempt to capture it with …Qc1, intending … Qxe6 next. On the surface, this seems like an unstoppable threat. White does not have a good way to defend the e6 pawn directly.
However, White can meet this threat strongly with Nd5!
If Black were to now capture the pawn with …Qxe6?, then the White knight forks the Black queen and rook on a8 after Nxc7!
If, however, Black were to capture the knight (for example, with …Nexd5), then after White recaptures with a pawn, then suddenly the e6 pawn has a friendly pawn defending it. With a protected passed pawn in the heart of Black’s position, White has the far better game.
Targeting The Weak d6 Pawn
As mentioned already, c5 is a key pawn break that White must look to play in the King’s Indian Bayonet Attack.
Once c5 has been achieved, White should initiate a capture on d6, as in the below position.
Once Black recaptures, d6 becomes a weak pawn that White can target. White’s dark-squared bishop already attacks it. Nb5 increases the pressure.
Black has only one good way to add a defender to d6 - with the rather unnatural Ra6. But even here, Black will struggle to hold on to their d6 pawn in the long term. For example, White can play Nd2 -> Nc4 to bring the other knight over to the queenside.
Remember: every position is different. But armed with these ideas, you should have enough to begin playing the King’s Indian Bayonet Attack to a good level!
