Your move 3...Bb4 is a pin with purpose. By putting the bishop on b4, you stop White from playing d4 without kicking the knight first. White’s e3 move has weakened their control of d4, and you are punishing that immediately. The pin also prepares ...e4 ideas in some lines, and it makes it harder for White to develop their pieces fluidly. You are not trying to win the game in one move — you are competing for the dark squares and making sure White’s extra central pawn does not give them a free ride. The statistics back you up: Black wins 46.4% of games from here (with 3.7% draws), which is very respectable for the second player. White's 49.9% win rate is barely above yours.
The Engine’s Top Move and the Most Popular Replies
The engine's best continuation for White is 4.Nge2, with the follow-up ...0-0 a3 Bxc3. That line leads to a symmetrical-looking structure where Black has traded the bishop pair for fast development and a solid position. But Nge2 is not the only move you will face. Here are the most common White replies and how they score, so you know what to be ready for: - 4.Nge2 (58,229 games) — White scores 50.9%. You castle and prepare to meet a3 by taking on c3. - 4.d4 (51,869 games) — White scores 50.0%. This is the most direct approach; Black can take or push. - 4.a3 (48,989 games) — White scores 48.8%. This move is actually an inaccuracy (see below). - 4.Nf3 (33,737 games) — White scores 48.7%. Also an inaccuracy. - 4.Qc2 (28,384 games) — White scores 51.2%. Prepares to break the pin. - 4.Nd5 (17,805 games) — White scores 53.6%, the highest winning percentage for White. This aggressive jump can be annoying, but Black has good resources.
Punishing White’s Inaccuracies
Two of White's most popular replies are actually mistakes that give you a real advantage if you know how to handle them. According to the engine's analysis: - 4.a3 loses about 0.5 pawns (the engine prefers Nge2). After a3, you can retreat the bishop to a5 or e7 — or sometimes take on c3 and trust your pawn structure. Black scores 51.2% from this position, which means you win more often than White does. - 4.Nf3 loses about 0.9 pawns — nearly a full pawn! Black scores 51.3% here. After Nf3, you can push ...e4, gaining time and space. The knight has to move again, and suddenly White's setup looks clumsy. Keep an eye out for these two moves; they are your best chances to take over the game early.
The Typical Plan: Castle and Trade
In the main line after 4.Nge2, Black's most natural plan is to castle kingside quickly (0-0) and wait for White to play a3. When a3 comes, you take the knight on c3: ...Bxc3. This trade gives up the bishop pair, but it serves several purposes. First, it removes a key defender of White's centre. Second, it gives Black a half-open b-file after ...bxa3 or ...bxc3 in some lines. Third, it simplifies the position, which is often what Black wants in a symmetrical English. After the trade, White recaptures with the knight from e2 (Nxc3), and the game takes on a quiet, manoeuvring character. You can aim for ...d5, ...Re8, or even ...b6 and ...Bb7. The engine says this is completely equal — your job is to play accurate chess from here, not to force a win.
