After 1.d4 Nf6 2.c4 c5 3.d5, you have reached the Indian Defense: Normal Variation, c5 line. On the surface this looks like a straightforward Benoni-style position, but the statistics are surprisingly tight — Black wins 48.9% of the time across nearly 1.9 million games, while White wins only 47.6% (draws make up the tiny remainder). That means correct play matters enormously from here. Stockfish rates the position at +0.75 in your favour, which means a lasting edge if you handle it well. The engine's top recommendation?

At depth 16, Stockfish recommends 4.b5 as White's strongest reply after 1.d4 Nf6 2.c4 c5 3.d5. This move looks aggressive because it immediately offers a pawn, but the idea is to open lines and keep Black off-balance. The engine's suggested continuation is: b5 cxb5 a6 e3. After Black captures on b5, White plays a6 to regain the pawn or create further weaknesses in Black's camp. This is not an easy line for either side — across 735,597 games where Black chose 3...b5, White scored only 43.8%, meaning it's a sharp fight where tactical awareness is essential. Do not play it casually; study the follow-up ideas like the a6 thrust before committing.
What Black Plays Most Often (and How You Score)
While the engine loves 4.b5, Black has several other moves that appear far more frequently in practice. The most popular is 3...e6 (478,581 games), where White scores 49.2%. This is a straightforward transposition to a Modern Benoni after ...exd5, so you should be comfortable there. Next is 3...d6 (349,554 games) where White actually scores a slightly favourable 50.2%; you proceed with normal development (Nc3, e4, etc.) and a space advantage. The fianchetto 3...g6 (132,852 games) gives White 48.9% — again solid. 3...e5 (72,757 games) scores 48.6% for White. A special shout-out goes to 3...a6: while only 41,412 games have reached this position, White wins a strong 53.5% there, often by playing 4.a4 to clamp down on Black's queenside expansion.
Your Practical Repertoire at the Board
With a +0.75 evaluation in your favour, you enter this position with a measurable edge — but the statistics show you must play accurately to convert. Against 3...b5 (the engine's favourite), be ready for a tactical scuffle: accept the pawn and then hit back with a6. Against 3...e6 (the most popular choice by a wide margin), prepare the standard Benoni treatment: keep your d5 pawn intact as long as possible, develop with Nc3 and e4, and castle kingside. Against 3...d6, your win rate actually ticks above 50%, so just play natural developing moves: Nc3, e4, Nf3, Be2, 0-0, and exploit your central space. The 3...g6 line typically heads toward a King's-Indian-style setup where you simply maintain your pawn centre. And if you ever see 3...a6, rejoice — that is your best-scoring opponent move at 53.5%, so push 4.a4 and enjoy the stats.

Frequently asked questions
Why does White score only 47.6% if the position is +0.75 for White?
A +0.75 evaluation means the engine considers White clearly better at top levels of play. However, the 47.6% win rate comes from games across all ratings on Lichess (1,894,488 games). In practical play, especially at club level, Black has many sharp counterplay options (the 3...b5 line alone accounts for 735,597 games, where Black scores 56.2%). The engine edge does not automatically translate into a won game — you still need to know the right plans, particularly against the tricky b5 and e6 continuations.
What is the best White move after 1.d4 Nf6 2.c4 c5 3.d5?
The engine's best move at depth 16 is 4.b5, which is a pawn sacrifice that leads to concrete play. The suggested continuation is: b5 cxb5 a6 e3.
