{ If I can describe the tempo of the Nimzo/Bogo Indian, I will say it is basically the opposite of the tempo of the Kings Indian. As we saw in the Kings Indian guide, those positions likely lead to unclear play where both sides are trying to outpace their opponent on their side of the board. Nimzo/Bogo are slower and quieter } 1. d4 Nf6 2. c4 e6 { d4 Nf6 c4 e6 is the starting position for the Nimzo/Bogo. 3. Nc3 leads to a Nimzo, while 3. Nf3 leads to a Bogo. They can transpose to one another, but usually, they lead to different setups in the position. This opening is known to be very solid, and it's played by grandmasters all the time (if not the most frequent defense against 1. d4) [%cal Gg1f3,Gb1c3] } 3. Nc3 Bb4 { As a higher level concept, the Nimzo/Bogo Indian are focused around the e4 square. White would ideally want to play e4 safely and take the full pawn center. Black could play d5 and play a Slav/QGD, but the Nimzo Indian takes an approach of stopping White's e4 without playing d5. [%csl Ge4] } 4. e3 { There are four major moves for White on move 4: Qc2, f3, a3, and e3. 4. Nf3 usually transposes back to a Bogo Indian. I will be analyzing each of these moves in detail below. } ( 4. Qc2 ) ( 4. f3 ) ( 4. a3 ) 4... b6 5. Bd3 Bb7 { You can see the battle for the e4 square already forming. Black wants to control e4 without pushing d5 } *

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 b6 { White has 3 different plans here: Ne2, Bd3, and Nf3. We will go over each of these moves in their own chapters. This chapter is dedicated to Ne2, which is the most challenging one to face. } 5. Ne2 { White's idea is clear: If Black plays Bxc3, white will recapture with the knight and not ruin the pawn structure, as is typically the case in the Nimzo Indian. } 5... c5 $5 { I recommend this rather unintuitive move. } ( 5... Bb7 { Bb7 is the most intuitive and Nimzo-Indian style. However, the problem is that the Nc3 will always stay there, even after Bxc3+ since the knights are connected. } 6. a3 Be7 ( 6... Bxc3+ 7. Nxc3 { Exchanging just loses the bishop pair with no real compensation. } ) 7. d5 { Looks quite ugly with both bishops hemmed in by White's space advantage. White scores very well in this position in practice } ) 6. a3 { Logical, tempting Black to give up the bishop. } ( 6. d5 O-O 7. a3 Ba5 8. g3 ) 6... Ba5 $5 { No trade! This is the idea of c5. Although unseen in pretty much every other Nimzo Indian variation, this line is particularly strong because it maintains the pin. White will do whatever it takes to push b4 safely and Black will prevent it } 7. Rb1 { Logical move to threaten b4, trapping the bishop } 7... Na6 8. Qa4 { Likely the most critical line here, so you MUST know how to combat Qa4. The threat is b4 to trap the bishop altogether. Do not give in and play Bxc3+! This line has been analyzed by computers, so better memorize the line. } ( 8. g3 Bb7 9. d5 b5 $5 { Picking at the pawn chain. Once c4 falls, d5 is looser } 10. Bg2 bxc4 11.

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 b6 5. Nf3 Bb7 6. Bd3 { Considered the "normal" development approach, White sets up the knights on f3 and c3 early, bishop on d3, and castles.

This kind of position can also reached in the 4. Nbd2 Bogo Indian. Black plants a knight on e4 followed by f5 and a rook and queen lift for a rapid attack. } 10. Nd2 Qh4 11. f3 Nxd2 12.
