Playing Against the Nimzo-Indian Defense: Bg5 – A Guide for White
You have just played 4.Bg5 against the Nimzo-Indian, and Black has answered with 4...c5, striking at your centre immediately. This is a sharp, principled response, and the position is dead level — Stockfish rates it -0.12, a tiny edge for Black that is essentially nothing. Out of more than 116,000 games from here, Black scores 53.6%, but that number hides a lot of variety in how White handles the position. The key is knowing which move gives you the best chance to fight back. Let's look at the numbers and find the right plan.

The centre is the battleground. Black's ...c5 pawn thrust challenges your d4 pawn, and Black threatens to trade on d4 or advance ...cxd4, opening lines for their pieces. Your bishop on g5 pins the knight on f6 to the black queen, which is a useful piece of pressure — Black cannot ignore it. But the pin also means your bishop isn't contributing to the fight for d4 directly. The engine points to Nf3 as the best move, developing a piece and supporting the centre. Notice that pushing d5 (32,505 games, the most popular choice) is very common but scores only 46.3% for White — not terrible, but not the top engine pick either. You want to keep the tension, not release it immediately.
The Engine's Recommendation: Nf3
The engine's best continuation is 5.Nf3, a natural developing move that defends d4 and keeps all options open. After 5...h6, 6.Bd2 is the accurate reply — retreating the bishop to a safe square rather than letting Black gain a tempo with ...hxg5. Then ...cxd4 leaves you with a solid, flexible position. White scores 44.6% with 5.Nf3 across 15,305 games. That is not the highest win percentage among the options, but the engine considers it the most principled path, and the score is respectable given the complexity. More importantly, Nf3 avoids the two moves the engine flags as clear mistakes: e3 and e4.
Two Moves to Avoid: e3 and e4
The statistics reveal two traps for White that cost real points. 5.e3 is the second-most popular move (31,824 games), but the engine calls it an inaccuracy that loses about a pawn. White scores only 39.8% from here — the worst score among the common moves except for e4. The problem is that e3 blocks in your light-squared bishop and does nothing to address the pressure on d4. Even worse is 5.e4, played 4,636 times. This is classified as a full mistake, losing about 1.4 pawns. White scores just 35.8% from here. The idea of expanding in the centre is understandable, but Black can counter-attack with ...d5 or ...Nxe4, exploiting the loose bishop on g5 and the unprotected knight on c3. Save e4 for a better moment.
What About d5 – The Most Popular Choice?
If you are looking at the board and thinking about pushing 5.d5 — the most played move, with 32,505 games — you are not alone. It scores 46.3% for White, which is your best result among the major alternatives to Nf3. But the engine prefers Nf3, and there is a reason: after d5, Black gets to play ...d6, ...e5, or ...b5 ideas that can create counterplay on the queenside. You are not losing with d5, but you are giving Black a clear target. The engine's line keeps more tension. Think of it this way: the Nimzo-Indian is an opening where Black wants to provoke a weakness. Stay flexible, develop naturally, and let Black commit first.

Frequently asked questions
Is the Nimzo-Indian Defense: Bg5 good for White?
The position after 4...c5 is dead level — Stockfish gives -0.12, an essentially neutral evaluation that slightly favours Black but is within the margin of error. White scores 42.6%, draws 3.8%, and Black wins 53.6% across over 116,000 games. The opening is perfectly playable for White, but you need to choose your fifth move carefully.
What is the best response to 4...c5 in the Nimzo-Indian Bg5?
The engine recommends 5.Nf3. This develops naturally, supports the d4 pawn, and avoids the inaccuracies of 5.e3 and 5.e4. The plan is to meet ...h6 with Bd2 and then recapture on d4 with the knight, keeping your pawn structure flexible.
Why is 5.e3 a mistake in this position?
5.e3 is classified as an inaccuracy that loses about a pawn. It blocks in your light-squared bishop and does nothing to challenge Black's control of the centre. White scores only 39.8% from here — significantly worse than with Nf3 or d5.
Should I play 5.d5 as White against the Nimzo Bg5?
5.d5 is the most popular move with 32,505 games, and White scores a reasonable 46.3% from it. While not the engine's top pick, it is far better than e3 or e4. The engine prefers Nf3 for its flexibility, but d5 is a playable human choice that leads to a closed, strategic fight.
