ECO A09 43,909 games Stockfish +0.34

After 1.Nf3 d5 2.c4 dxc4 3.e3, White has offered a gambit that looks innocent but carries real bite. You, as Black, have just played 3...Be6 — a solid developing move that defends the c4 pawn and prepares to bring your pieces out. The engine gives White a small edge here (+0.34), and the statistics across nearly 44,000 games show White winning 53.4% of the time, Black 42.7%. That means the position is tougher for you than the early move count suggests. The drill below will help you navigate the critical next moves and punish White if they play too loosely.

What Black is fighting for

Your main idea with ...Be6 is simple but effective: you protect the extra pawn on c4 while developing a piece. In the Réti Gambit, Keres Variation, White typically wants to regain the pawn quickly and build a strong centre. By keeping c4 defended, you force White to spend time and energy reclaiming material — time you can use to complete development and castle. The trade-off is that your pawn on c4 can turn into a target, and if White plays accurately (starting with Nc3), they will pressure you immediately. Your job is to hold onto the structural edge without falling behind in development.

The engine’s top move and the most-played replies

From this position, Stockfish recommends Nc3 as White's best continuation, scoring 52.6% for White across 10,727 games. After Nc3 Nc6 Be2 Nf6, Black has solid development and a comfortable game despite the slight engine edge for White. The most popular response by White, however, is Qa4+ (9,412 games), which scores only 50.2% — meaning Black actually has a healthier winning percentage there than against Nc3. If you face Qa4+, the check is annoying but you can block with ...Nc6 or ...Bd7 and keep the pawn. The sharpest option is Na3 (7,371 games), which scores a massive 61.1% for White — that's the line you need to study most carefully. After Na3, White threatens Nxc4, and you must have a good response ready.

Two inaccurate White moves you can punish

The statistics identify two White moves that fall short of the best play — and you should know how to handle them. Nd4 (5,310 games) is an inaccuracy that costs White about half a pawn. The knight looks active in the centre, but it can be chased away with ...c5, forcing it to retreat before it has done anything useful. Ne5 (1,739 games) is even worse, losing roughly 0.7 pawns compared to Nc3. Here the knight on e5 is vulnerable to ...f6 or ...Bd6, and White has neglected the important d4 square. If your opponent plays either of these moves, you have a real chance to seize the initiative — don't let the opportunity slip.

Why the statistics matter for your game plan

With 43,909 games played from this exact position, you have a reliable dataset to guide your decisions. The 53.4% White win rate tells you that the opening is slightly better for your opponent overall, but the 42.7% Black win rate is far from hopeless — these are fighting positions, not lost ones. Notice that Black draws only 3.9% of the time, the lowest outcome. That's a sign that the Réti Gambit, Keres Variation leads to unbalanced, tactical middlegames where both sides play for a win. If you enjoy dynamic positions with clear plans and few quiet manoeuvring phases, this opening is a good fit for your repertoire as Black.

Frequently asked questions

Should Black hold onto the c4 pawn in the Réti Gambit, Keres Variation?

Yes, generally you want to keep the pawn as long as it doesn't cost you development or king safety. Your move ...Be6 defends it, and White will often spend a tempo removing it with Nc3 or Na3. If White plays Qa4+, you can block with ...Nc6, keeping the pawn protected.

What is the main threat after 1.Nf3 d5 2.c4 dxc4 3.e3 Be6?

White's biggest threat is Nc3, attacking the c4 pawn and preparing to recapture. If White plays Na3 instead, the threat is the same (Nxc4), but the knight on a3 is less centralised — you can try to exploit that with moves like ...a5 or ...Bxa3 in some lines.

Is the Réti Gambit, Keres Variation good for Black?

Statistically, White scores 53.4% in practice, and the engine gives White a small edge (+0.34). That means you are slightly worse as Black, but the position remains fully playable. Your 42.7% win rate shows that Black has good practical chances, especially if White makes an inaccuracy like Nd4 or Ne5.

How should Black respond to White playing Qa4+?

Qa4+ is the second most common move (9,412 games), but White scores only 50.2% there — your best score among the main replies. You can simply block with ...Nc6, which develops a piece and maintains the defence of c4. If ...Bd7 is also possible, but ...Nc6 is more natural and puts pressure on the e5 square.
