Sicilian Defense: Lasker-Dunne Attack with ...Nc6

The Lasker-Dunne Attack avoids the sharp theoretical battles of the Open Sicilian (2.Nf3) and steers the game toward a quieter, more strategic fight. By playing 2.g3 and 3.Bg2, you prepare to castle quickly and keep your kingside solid. Black's ...c5 already controls d4, so you will likely challenge the centre later with moves like d3, Nc3 or Ne2, and maybe c3 or f4. The position is fully equal, so your task is to outplay your opponent in the middlegame — not to memorise a knockout line. The engine's suggested reply is 3...g6, setting up a double fianchetto or a King's Indian-style setup, but Black's most popular move at club level is 3...e5.

Black plays 3...e5 in 128,075 games, making it the single most common response. By doing so, Black seizes space in the centre and stops your d4 break. White scores 49.7% here — very close to the overall average. A natural plan is to play d3, Ne2 (to keep the g2-bishop's diagonal open), O-O, and then consider f4 or Nbc3 to fight for central control. Don't rush to break with d4 immediately — Black's pawn on e5 makes that difficult, so build up slowly. Your king is safe, and the game will revolve around whether you can open lines for your fianchettoed bishop.

The engine's top choice is 3...g6 (85,399 games), continuing g6, Ne2, Bg7, O-O. Here White scores 46.5% — the lowest win percentage against any major reply. Why? Because Black mirrors your setup and prepares to fight for the dark squares. After 4.Ne2 Bg7 5.O-O, you can play d3, Nbc3, and maybe h3 or Be3. The key is to avoid letting Black's bishop on g7 dominate the long diagonal. You can consider an early d4 break once your pieces are developed, or play on the queenside with a3 and b4. Since Black scores well here, stay alert and don't let your opponent equalise too comfortably.

Black has several other solid options. 3...d6 (107,952 games) scores 48.2% for White — Black prepares ...Nf6 and ...g6 or ...e5, heading into a kind of Closed Sicilian. 3...e6 (106,174 games, White 48.8%) keeps the position flexible and can lead to a Hedgehog or French-like structure. 3...Nf6 (54,809 games, White 48.6%) attacks e4 immediately; you can reply d3 or Nc3, keeping your g2 bishop active. And 3...b6 (11,348 games, White 51.2%) is Black's most losing move — the only one where your win rate tops 50%. After 3...b6, Black commits to a queenside fianchetto early, and you can take the centre with d4 or play Ne2 and O-O with a comfortable edge.

In this position, Black's typical errors fall into two categories: playing too passively and allowing you to seize the centre with d4, or pushing too aggressively on the kingside and leaving the c5-pawn weak. If Black plays something like ...a6, ...Rb8, and ...b5 without developing, your g2 bishop becomes a monster on the long diagonal. The engine's best line — 3...g6 4.Ne2 Bg7 5.O-O — shows that Black should develop quickly and fight for the dark squares. If your opponent dawdles or misplaces their pieces, activate your knight to c3 or d5, open the centre with d4, and turn your fianchettoed bishop loose.
