Chess openings: Part II: Bogo-Indian defense
This is the second part of my opening repertoire. So I have chosen a very interesting defense by black , which is called as Bogo-Indian after Soviet grandmaster Efim Bogoljubov.
So, before we begin , I just want to say you must be very careful while playing this defense.
There are several variations which you must know. Keep in mind that white won't play Nc3 to block check, as it'll transpose into Nimzo-Indian , but don't white just avoided it by playing Nf3. So , white's main option here is Bd2!
Here blacks main move is Qe7(Nimzowitch variation) . I do recommend this move ,if you are an attacking player and won't be pleased with draw.
The second option is just Bxd2 trading the same colored bishops .
The 3rd option is to play 4...a5 , which is Bronstein variation and is very sharp try from blacks to expand on the queenside at a cost of structural weaknesses.
After Qe7 , white's main option is 5.g3 , to which black will reply Nc6. The main line continues 6. Nc3 Bxc3 7. Bxc3 Ne4 8. Rc1 0-0 9. Bg2 d6 10. d5 Nd8 11. dxe6 Nxe6 and the position is equal with good chances for both sides.
Another option for white is to play 4.Nbd2 , but this is kind of a cramped situation for white, as knight is developed in a place not so good for it, and besides block the bishop. So Bd2 is the most reasonable approach to this.
There is a very good point to play this defense . Blacks are going to attack from the very start.
This was a brief tour of this defense. And I advise you to play this defense as black , I also have lots of victories with this.
