This is your page: you're playing Black, and your task is to handle White's initiative without letting the position slip. The engine gives a tiny edge to your opponent, so you are slightly worse — but with accurate play you can neutralise White's early activity and steer toward a comfortable middlegame.

The Position You're Fighting For

The pawn on c4 is gone, you've challenged the centre with ...c5, and White now has a decision to make. The engine's best continuation begins with Bxc4, which develops a piece and recaptures the pawn. White scores 52.1% from this line across nearly 2,000 games — a solid but nothing overwhelming result. What you're fighting for is a clean, well-coordinated setup where White's space advantage doesn't turn into a direct attack. Your bishop on c8 is still at home, your king isn't committed, and you have ...Nc6 and ...e6 or ...g6 as natural ideas to complete development. The key is to survive the opening without making a structural concession.

The Engine's Main Line and Your Response

Stockfish's top choice is 5.Bxc4, and the most common reply from Black is 5...Nc6, developing with a threat to the e4 pawn. The engine continues 6.b4 — a sharp thrust to undermine your c5-pawn and open lines. If you capture with 6...cxb4, the position opens up but your queenside pawn majority can become a long-term asset. The critical thing is not to panic. White's b2-b4 is ambitious, but your ...a5 or ...b6 ideas in response can keep the balance. Black scores a respectable 44.3% overall in this position, meaning something like 48% of non-drawn games — close to equal chances in practice.

Three Mistakes White Can Make (and How to Punish Them)

Because this line requires accuracy from both sides, White has several tempting but wrong moves. The statistics flag three clear errors to watch for: Qa4+ — An inaccuracy that loses about 0.7 pawns of advantage. If you see this, block with ...Bd7 and you'll have development and tempo. White should have recaptured on c4 instead. e5 — Another inaccuracy costing roughly 0.7 pawns. Pushing the e-pawn again weakens White's centre and lets you take over with ...Nc6 and ...dxe5 or similar. b4 — A true mistake losing around 1.2 pawns. If White plays 5.b4 immediately, you can capture with ...cxb4 and enjoy a comfortable extra pawn with no immediate compensation. Learn to spot these three moves — if White plays any of them, you can seize the advantage.

Why This Opening Suits Your Style

The Réti Accepted with e4 is an excellent choice if you enjoy positions with clear plans and limited theory. Black's task is straightforward: finish development, keep the king safe, and use the extra c-pawn to create counterplay on the queenside or in the centre when White overreaches. The database shows White wins 51.9% of games — a number that drops from White's normal first-move advantage — meaning Black is doing well here. The 3.8% draw rate also signals that the position is fighting chess; it rarely fizzles into a quiet draw. If you like active defence and outplaying opponents who misjudge the position, this line is for you.

Frequently asked questions

Is the Réti Accepted with e4 good for Black?

It's fully playable. The engine gives a +0.36 edge to White, meaning Black is slightly worse but nothing more. In practice Black scores 44.3% across over 2,000 games, which is a healthy result — many openings where White pushes for an edge give Black less than that.

What should Black do after 5.Bxc4 Nc6 6.b4?

The most principled reply is 6...cxb4, accepting the pawn sacrifice. You get a queenside pawn majority and open lines for your pieces. White gets some development compensation, but Black's position is solid and the extra pawn can matter in the long run.

How can Black punish White's mistake 5.b4?

If White plays 5.b4 instead of recapturing on c4, that's a mistake costing roughly 1.2 pawns. Simply capture with 5...cxb4 and you're up a clean pawn with no obvious compensation. White has no immediate threats, and you can follow up with ...Nc6 and ...e6 to complete development.

Why does White play b4 in the main line?

After Bxc4 Nc6, the move b4 aims to challenge your c5-pawn immediately, open the b-file for White's rook, and create space for the bishop on b2 or a3. It's the engine's top choice and represents White's best attempt to turn the central space into an initiative before you finish development.
