ECO B47 26,936 games Stockfish +0.23

The Sicilian Taimanov with 5.Nb5 leads to a sharp, hypermodern struggle where Black has already grabbed space on the queenside and is ready to challenge White's centre. After 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nb5 d6, you have reached a key tabiya. The engine calls this dead level (+0.23), and the statistics back that up: across nearly 27,000 games, Black actually scores a slight edge with 50.8% wins. The drill below will help you learn how to handle White's most dangerous tries and where to punish their inaccuracies.

What Black Is Fighting For

In the Taimanov, Black's central structure (d6 and e6) is solid but flexible. Your pawn on d6 controls e5, while your e6 pawn keeps the d5 square under watch. The knight on c6 is well-placed, and after you develop your kingside pieces, you will often look to play ...a6 to chase White's knight on b5, or ...d5 to strike in the centre at the right moment. The position is very balanced: the engine gives +0.23, a tiny edge for White that is too small to matter in practice. That means from your perspective, you are completely fine — this is a position to play chess, not to survive. The 50.8% Black win rate confirms that club players who know this set-up score better than White does.

The Engine's Top Move: c4

Stockfish's best answer for White here is c4, a strong central pawn advance that prepares N1c3 and puts pressure on Black's d6 pawn. The full recommended line runs: c4 Nf6 N1c3 Be7. White aims to build a broad centre and restrict Black's ...d5 break. This is the most principled challenge, and it keeps the game complex. White scores 49.1% with c4 across over 5,000 games — statistically neutral. As Black, your task is straightforward: develop the knight to f6, tuck the bishop to e7, castle, and then decide whether to play ...a6 (to ask the knight on b5 where it is going) or ...b6 to fianchetto on the queenside.

Three White Mistakes to Punish

The statistics identify three inaccurate moves that lose significant equity compared to the engine's best. If White plays any of these, you should sense an opportunity: - Be3 (958 games): an inaccuracy that loses about 0.6 pawns (the engine says c4 was better). White's bishop on e3 blocks the queen and does nothing active. Continue with Nf6 and a6, and you will enjoy easy development. - Be2 (825 games): another inaccuracy losing roughly 0.6 pawns. The bishop is passively placed. Again, develop with Nf6, Be7, and prepare ...a6 to harass the b5 knight. - Bd3 (539 games): the worst of the three, losing about 0.7 pawns. The bishop on d3 does not help White's centre and can be a target. After Nf6 and a6, Black will claim a comfortable edge. When you see any of these moves, you can be confident that your position is already superior — just keep developing and you will outplay them.

Frequently asked questions

Is the Sicilian Taimanov with 5.Nb5 good for Black?

Yes, it is one of Black's most reliable Sicilian lines. The engine evaluates the position at +0.23, which is essentially dead level. In practice, Black actually scores 50.8% across almost 27,000 games — slightly better than White. It leads to rich, balanced positions where strategic understanding matters more than memorisation.

What is the best move for White after 5...d6?

The engine recommends 6.c4, aiming to control the centre and support N1c3. That line scores 49.1% for White, which is statistically neutral. The most popular move is 6.N1c3 (over 10,500 games), but White scores only 41.2% with it — a poor result that makes it less threatening than its popularity suggests.

How should Black respond to 6.Bf4 in the Taimanov: Nb5?

6.Bf4 is the second most common move and scores a solid 53.1% for White, so it deserves respect. The bishop pins the knight on c6 and can support an e5 push. Your best plan is to develop naturally with Nf6 and Be7, then castle quickly. Avoid weakening the d6 pawn unnecessarily, and look to challenge White's centre with ...a6 or ...d5 at the right moment.

Which White moves are considered inaccuracies in this position?

Three moves are flagged as inaccuracies: Be3 (losing about 0.6 pawns), Be2 (also losing about 0.6 pawns), and Bd3 (losing about 0.7 pawns). All of them place the bishop on a passive square when c4 was stronger. If your opponent plays any of these, you can play confidently — develop your pieces and you will already be slightly better.
