Preview by the author. This is the starting position of the Bogo-Indian defense. The opening is named after Efim Bogoljubovwho was the first really strong player that employed this opening on a regular basis back in 20’s and 30’s years of the previous century. So, Black gave a check as early as on move three. White has, obviously, three options: Nc3 – would turn defece game into the Nimzo-Indian.
For the White defenc, who prefer the Nimzo, I suggest to start with 3. Nc3 and after Bb4 White has much more options. Here the first player would already be limited, as the kingside knight is already developed on f3. Nbd2 – is an option, where White aims to push black’s bishop by a2-a3 and, either forcing the bishop to retreat, or to swap bishop for a knight, which would yield White a pair of bishops.
The drawback of 4. Nbd2 incian that the knight is passively placed and somehow obstructing the natural development of other white pieces.
Bd2 – is the most natural option, which would be the topic of current survey. White is not aiming to get the pair of bishops, but is continuing the normal development, counting on his space advantage in the center.
What I like about the line 4. Bd2 is that White’s play is natural and positionally sound. It’s true that often White’s advantage will be marginal.
However, I strongly believe that when your opening is based on a good positional ground, it’s easier, at least from practical point of view, to handle the position in the middlegame as well.
Structure of the database. The main position arises after the moves: GM Postny provides you with full repertoire against all of them divided to 8 chapters. This move was tried several times by Magnus Carlsen and definitely deserves serious attention. The Israelian Grandmaster recommends to meet this with 5.

Bogo Indian Defence by GM Magesh and GM Arun
White exchanged the nasty — b4 pawn and later will develop the knight on c3. Black has 3 options here: In Chapters 3, 4 and 5 deals with the tricky move 4…a5. This is probably the most serious alternative to the main line nogo. Black keeps all his options.
White should continue with 5. This system is examined in Chapter 3.
Classical Repertoire Against Bogo – Indian Defence
An immediate play through the center by 5…d5 is examined in chapter 4. The most common setup is analysed in chapter 5. Black plays 5…d6 followed by Nbd7 and e5. The light-squared bishop will be developed on b7 and it will become a worthy opponent of White’s fianchettoed bishop. In this scheme, however, defenfe usefulness of the move a7-a5 is not entirely clear.
In this position Inndian claims an advantage for White after two moves 8. According to his analysis Black is far from equality in this line. In this line Black is playing through the center at an early stage. Bg2 is transposing to Catalanso the author offers 6. Probably this chapter will be interesting for Catalan players as well, because after Here the author followed the old game Kramnik — Topalov and offers a few improvements.
The conclusion is that the verdict of this line remains the same — White is slightly better. Here the reader can find the most common continuation 5…d6 with the idea 6…Nbd7 and 7…e7-e5.
As always Evgeny managed to propose us a very interesting continuation against this nasty line. After the moves 6.
In general, it makes sense to move the bishop in order to create a threat a2-a3, but where to move it? Back to c1 is strange; forward to g5 is okay, but the bishop will be kicked away by h7-h6 at some point.
So, e3 appears to be the most suitable square”. Finally, we reached the main line in Bogo-Indian defense. In this chapter the author examined the position after 5. Postny advocates the strange looking move 7.
In the following analysis you can find the details, but it is obvious that White is doing very well in this line. In this chapter author analyses 6… 7. After 7…d6 the most obvious move 8. White keeps better chances due to his space advantage. The situation is a bit more complicated in the line with 7…Na5.
Here the main move for many years was the natural 8. Qc2 Rfc8 followed by d7-d5 or c7-c5according to circumstances. Even though it was played in only 18 games so far this move poses serious problems to Black and White is better in all the lines after it.
We finally reach an absolute main line of Bogo — Indian defence with 4. It appears after the move 6…Bxc3 7. White should continue with 8. Rc1 -White has grounds for a slight, but stable advantage.
White’s main trump is the space superiority. Black, on his part, is normally trying to build his counter play on the dark squares and after the moves 8… 9. Rxc3 we reached a first crossroad for Black — the knight can go to b8 and d8. The author proves that 11…Nd8 is playable, but White easily achieved a better game, by pushing c4-c5 in an appropriate moment. The main line for many years is 11…Nb8 and now White gives part of his space advantage, but opens the long diagonal for his bishop.
