What’s a King’s Indian defense?

The king’s Indian defense is a very common chess opening. It is dynamic and complex, but it allows the black to set a base for a strong defense in the game. The opening is usually employed by black when white starts with the queen’s pawn opening to d4.

As such, the logic behind the defense is to let white establish control in the center of the court and yet despite ceding this control, black builds a very strong defense around the king and develops its minor pieces early on in the game.

The offensive strategy of black would then be to counterattack where white seems to be weakest.

However, the development and continuous evolution of the opening theory mean that many successful variations have been made to the king’s Indian defense over the years. Some of the most important variations to the opening would be studied alongside the mainline. One thing remains constant, though; the first move in the king’s Indian defense and its variations is a move of Nf6 (Knight to F6) by black in response to the d4 (Queen’s pawn to D4) of white.

How to reach it

King's Indian Defense: What Is It and How to Use It?Now, after the black Nf6 move has been made, the play is expected to continue as follows on both sides of the chessboard:

  1. d4 (white) – Nf6 (Black)
  2. c4 – g6
  3. Nc3 – Bg7
  4. e4 – d6King's Indian Defense: What Is It and How to Use It?

An exception to the development of this formation for black can occur as a result of variations in the attack of white. Though the opening is considered to be a strong defensive one nowadays, it was originally seen as suspect because it went against conventional chess opening of attempting to establish control over a part of the board from the off. This is why the opening is considered to be a passive one, and many aggressive players find it unsuitable.

As a result of control being with the white at the onset, the pawn structure of the white for the offense would be superior to that of the black. But the flexibility with which black could attack could turn the tide.

Why using it?

Despite the passive nature and seeming offensive unsuitability of the opening, it is mostly used to lure the white into feeling secure as control over the center rest with it. The opening, however, allows for the black to build a difficult penetrate the defense and develop its minor pieces in a way that allows them to attack batter later on in the game.

Firstly, the fianchetto that is made on the kingside bishop allows the king to quickly find safety in the possibility of castling with the kingside rook.

The nature of the opening means that black is usually perfectly poised to attack the kingside while white is likely to proceed to a queenside attack. Whichever attack is coming off quickest and effective is likely to get the checkmate. A potential failure of the whites to create counterplay on the queenside would prove detrimental to their cause.

Moves explained

King's Indian Defense: What Is It and How to Use It?As earlier stated, there are variations to the opening that could be used to account for a change in the moves of the white or to create a middle game more suitable to your strategy.

It should be noted that keeping track of and understanding some of the moves that would be identified here is quite difficult without visual demonstration. You could provide such visual stimulation by acquiring a chessboard and moving both white and black pieces yourself.

If the kings Indian defense is being utilized in its original structure without variations, white should be looking to:

  1. Get as much space as possible around with its pawn structure in the 4th rank
  2. Play to retain the tension in the center structure and make moves to weaken the development of black pawns
  3. If pawns are fixed by pushing d5, make moves to attack the queenside

On the other side of the board, the black should be looking to:

  1. Try to force the pawn on d4 to push to d5. This would solidify the center for white but allow the black to attack the kingside more effectively
  2. If the push to d5 was successful, moving the kingside knight to push f5 could open up attacks in the kingside

The variations to the king’s Indian defense are considered in moderate detail below.

Sämisch variation

King's Indian Defense: What Is It and How to Use It?In this variation, you should see a white move away from the kingside and castle queenside, thus, negating the kingside attack of black as there are no game-ending targets to attack.

Also, white should move to get the queen and bishop on the same diagonal while eyeing h6, while f3 should block the knight from moving to g4.

On the other side, black should look to delay castling due to the strong Be3/Qd2 barrage of white.  Also, counter plays on the queenside should be developed in case of a pawn cascade resulting from queenside castling.

Looking up examples of this variation would show how the openings could translate to an effective middlegame.

Petrosian variation

King's Indian Defense: What Is It and How to Use It?The Petrosian variation results from pushing d5 in the original Indian defense. White should be looking to push b4 first, then c5 to establish an attack at the base of its central pawn structure. Also, moves that could potentially lead to a lockdown of the pawns in e, d, and f files should be avoided as such a move would result in the black kingside attack being even stronger due to the proximity of the pawns to the king.

The black would look to make such a lockdown a reality by pushing f5 and maybe f4. Alternatively, black could push g5-g4-g3 and eventually h5-h4-h3 though the game could devolve into white and black, both attacking the queenside and kingside, respectively, before such a move may be possible.

Four pawns variation

King's Indian Defense: What Is It and How to Use It?In the four pawns variation, white should be looking for opportunities to push f5 or e5 to strengthen the central pawn push. The main disadvantages of this variation to the white are that it is overextended, and the development of its other major pieces is lagging. However, if black remains too passive, this too strong center would be difficult to beat once the white offense gets going.

For the black, a castle should be considered because the whites’ other pieces are not ready yet, and e5 has been pushed regardless. The knight could also be moved back to e8. This, combined with attacking d4 with c5, would force d5 and e6 to attack, leaving an opportunity to attack the e4 pawn.

Final thoughts

Any chessboard could be used to carry out the demonstration or practice of these moves and their follow-ups. From travel chess set to a more intricate set, the best chess board should meet your requirements (such as weight) for use.

It should be noted, though, that this piece only looks at the variations and some possible scenarios that could arise as a result. Other possible developments could follow the opening.

Watching past matches involving the use of the king’s Indian defense and its variations would provide a complete understanding of how the moves can interact to influence the middle and end games. This should nevertheless be enough to prove how intricacies in the opening to a game could affect the development and effectiveness of the middlegame and endgame.
