The move 3.b3 is the cornerstone of this variation. You're preparing Ba3 or Bb2, placing your bishop on the long diagonal where it eyes Black's kingside and the centre. Unlike a queen's pawn opening where you immediately claim space with d4, here you keep the tension flexible. Black has already committed to ...c6, which supports ...d5 but can make ...dxc4 a common freeing attempt. Your job as White is to maintain pressure on the d5 pawn, develop harmoniously, and be ready to recapture with the b-pawn if Black takes on c4 — opening the b-file for your rook. The engine's top choice is 3...Bf5, but whatever Black plays, your plan remains consistent: finish development, decide where to place your king (usually kingside), and exploit the half-open centre that often results.
The Engine's Recommendation: Bf5 and the Best Response
At depth 16, Stockfish recommends 3...Bf5 as Black's most principled reply, followed by Ba3 Nd7 e3. So after 3.b3 Bf5, you play 4.Ba3. Why Ba3? It develops the bishop to an active square, pins the ...e7 pawn indirectly (since Black might want to play ...e6), and keeps options open. Then after 4...Nd7, 5.e3 solidifies your centre and prepares to recapture on c4 with the pawn if needed. This line keeps the game in quiet, manoeuvring territory where piece activity matters more than direct attacks. The evaluation is dead even — -0.07 means the engine sees no advantage for either side. For you as White, that's a perfectly fine verdict: you've navigated the opening without disadvantage and the game is yours to play from here.
What the Statistics Tell Us About Black's Choices
The database of 55,751 games reveals how Black actually responds, and the results might surprise you. Here are the most-played moves and your winning chances against each: - 3...Nf6 (21,948 games, White scores 51.2%) — the most popular reply. Develops naturally; White continues with Bb2 or Ba3 and e3. - 3...Bf5 (8,883 games, White scores 51.9%) — the engine's top pick. You respond with 4.Ba3 as above. - 3...Bg4 (8,471 games, White scores 50.3%) — pinning the knight. Just play Bb2 or e3; the pin isn't dangerous. - 3...e6 (5,746 games, White scores 55.4%) — your best numerical result. Black blocks the c8-bishop; get your pieces out quickly. - 3...dxc4 (4,335 games, White scores 54.2%) — Black takes the bait. Recapture with bxc4 to open the b-file and maintain central influence. - 3...d4 (1,427 games, White scores 52.2%) — Black pushes prematurely. You can meet this with e3 or d3, challenging the pawn. Across the board, White scores above 50% against every single Black reply, and above 54% against the most cooperative moves.
The Most Common Mistake and How to Avoid It
While the FACTS don't list explicit mistake moves, the biggest practical error in this opening is forgetting why you played b3 in the first place. Many White players fianchetto the bishop then neglect it, or rush to play d4 too early when the position calls for patience. Against 3...dxc4, a common slip is recapturing with the queen or knight instead of bxc4 — opening the b-file with your pawn is a key strategic asset here. Another pitfall: after 3...Bg4, don't panic. The pin on your f3-knight is temporary; simply play 4.Bb2 or 4.e3 and develop normally. Black's bishop on g4 often becomes a target later. Remember: this variation scores well for White precisely because it's easy to play natural, principled moves. Don't overcomplicate it.

Frequently asked questions
Is the Réti Anglo-Slav Bogoljubow a good opening for beginners?
Yes. The move 3.b3 leads to clear plans — fianchetto the bishop, control the centre from afar, and keep the position flexible. White scores 51.9% across over 55,000 games, and the evaluation is dead level at -0.07, meaning you won't be worse out of the opening if you play natural moves.
What is the best response to 3...dxc4 in this variation?
Recapture with 4.bxc4. This opens the b-file for your rook, activates your queen's bishop after Ba3 or Bb2, and keeps a pawn in the centre. Statistically, White scores 54.2% against this reply, so it's a favourable line for you.
How do I handle 3...Bg4 pinning my knight?
Don't worry about it. Play 4.Bb2 or 4.e3 and develop normally. The bishop on g4 is annoying but not dangerous — you can later chase it away with h3 or let it remain. White scores 50.3% against 3...Bg4, so the game stays balanced.
Why does White score 55.4% against 3...e6?
The move 3...e6 blocks Black's c8-bishop, making it harder for Black to develop that piece. You can take advantage by completing your development with Bb2 and e3, then deciding whether to aim for d4 or keep the tension. It's Black's worst-scoring reply for a reason.
