When you play 2...g6, you are preparing to fianchetto your dark-squared bishop to g7. This is the heart of the Old Benoni. The pawn on d5 has already split the board into two distinct zones: White has a space advantage on the queenside and centre, while you will target the d5-pawn and the light squares around it. Your bishop on g7 will become a powerful piece, staring down the long diagonal at White's queenside. The position is closed, meaning manoeuvring and piece play matter more than rushed tactics. Your immediate goal is to complete development with ...Bg7, ...d6, and ...Nf6, then decide whether to strike with ...b5 on the queenside or keep the tension. White's +0.84 evaluation reflects their extra space, but your position is solid and rich with counterplay — the winning percentages prove this is no one-sided affair.
The Engine's Answer: Nc3 and How to Meet It
Stockfish's top recommendation for White at this position is Nc3, continuing Nc3 Bg7 e4 d6. This is the most principled line: White reinforces the d5-pawn, stakes out a big centre with e4, and says, 'try to break me.' Your response is straightforward: develop your bishop to g7, then play ...d6 to give your bishop an open diagonal and prepare ...Nf6. You are not in a rush. The position remains closed, and your counterplay will come from undermining White's centre with moves like ...e6 or ...b5 later on. Do not panic about White's space advantage — it comes with weaknesses. The d5-pawn can become a target, and your fianchettoed bishop is a long-term asset.
What the Statistics Reveal: The Most Popular Replies
The most-played move for White is 3.c4, seen in over 113,000 games, where White scores 49.3% — essentially no advantage. Your plan is the same: fianchetto, develop, and look for pawn breaks. The second most popular is 3.e4 (55,436 games, White scoring just 47.8%), which actually scores slightly worse for White than the average. This is good news for you. The engine's top choice, 3.Nc3, has only been played 12,094 times, with White scoring a meagre 46.9% — that means Black actually outscores White from that position! The key insight: White's 'best' moves don't translate to practical success. Your position is harder to play for them than the evaluation suggests. Other moves like 3.Nf3 (9,136 games, 47.4% for White) and 3.Bf4 (4,293 games, 43.2% for White) are less common but all give Black excellent practical chances.
One Mistake to Punish Immediately
The statistics flag 3.c3 as a known inaccuracy, losing about 0.6 pawns compared to the better 3.e4. This is a move that weakens White's control of the centre without accomplishing much. If your opponent plays 3.c3, you should be alert. The move is passive — it doesn't challenge your setup or prepare a clear plan. Your standard development with ...Bg7, ...d6, and ...Nf6 is already good. The evaluation shift shows that White has made your life easier; seize the chance to complete your development harmoniously and look for an early ...e6 break to challenge the d5-pawn directly. Recognising inaccuracies like this is how you turn a slightly worse position into a comfortable one.

Frequently asked questions
Is the Old Benoni d5 a good opening for beginners?
Yes, it can be. The pawn structure is clear, the plans are straightforward (fianchetto your bishop, attack the d5-pawn), and the practical results are excellent — Black wins 48.4% of games at the club level. It avoids heavy theory and forces your opponent to find accurate moves from move 2.
What is the best move for White against the Old Benoni d5?
The engine recommends 3.Nc3, preparing e4 to reinforce the centre. However, in practice, White scores slightly worse with 3.Nc3 (46.9%) than with the more popular 3.c4 (49.3%). So your chances are good regardless of which move they choose.
Should I be worried about the +0.84 evaluation as Black?
Not much. A +0.84 advantage for White is significant in engine terms, but in human play, the position is rich and complex. Black's winning percentage (48.4%) is virtually identical to White's (48.3%), showing that the Old Benoni is a perfectly practical choice.
What is the biggest mistake White can make in this position?
Playing 3.c3 is a known inaccuracy, costing White about 0.6 pawns. It's a passive move that doesn't help White's development or challenge your setup. If you see 3.c3, you can be confident you've already outplayed them in the opening.
