Indian Defense: Normal Variation
2.c4 adds a second pawn to the fight for d5 and takes space on the queenside. Black has not yet touched a central pawn, so the next move decides which opening the game becomes. Each reply sets up a different pawn structure, and learning this position is mostly learning which structure you want.

Key moves
1. d4 Nf6 2. c4
- 1... Nf6The knight covers e4 and d5, so White cannot play e2-e4 for free. Black also keeps every pawn at home, leaving the decision between ...d5, ...e6, ...g6, ...c5 and ...e5 for later.
- 2. c4The c-pawn backs up d4, eyes d5 and gains room on the queenside. It also opens the d1-a4 diagonal for the queen. The trade-off is that d4 can no longer get support from a pawn on c3, which is why ...c5 and ...e5 are direct ways to hit it.
Which second move leads where
2...e6 keeps several doors open. After 3.Nc3 Bb4 it becomes the Nimzo-Indian, after 3.Nf3 b6 the Queen's Indian, and with ...d5 it can turn into the Queen's Gambit Declined.
2...g6 fianchettoes the king's bishop. Black can then choose the King's Indian with ...d6 and ...e5, or the Grunfeld with ...d5, hitting White's center from the side.
2...c5 and 2...e5 are pawn strikes at d4. The first leads to Benoni structures once White pushes d5, and the second is the Budapest Gambit.
Why ...d5 waits for ...e6
If Black plays 2...d5 at once, 3.cxd5 Nxd5 4.e4 kicks the knight and hands White a broad center with gain of time. Preparing ...d5 with ...e6 means Black can recapture on d5 with a pawn, keeping a foothold in the middle.
A King's Indian setup
2... g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O
White builds a full pawn center on c4, d4 and e4. Black lets it happen, tucks the king away and plans to challenge the center later with the pawn breaks ...e5 or ...c5, which open the long diagonal for the g7 bishop.
Top replies by rating
The e6 move leads at most levels, but g6 draws level with it at 1800 to 1999. From 1800 up, the c5 strike climbs into the top three.
Questions
Does 2.c4 force Black into one structure?
No. That is the point of 1...Nf6: Black keeps the center pawns back, so after 2.c4 the full range of Indian setups is still open. White's third move often narrows it further, for example 3.Nc3 allowing ...Bb4.
