Black's move 3...Bb4 pins the c3-knight against the white king. This is your main weapon in the Classical Nc3 line. The pin immediately discourages White from an aggressive central break, because the knight on c3 is tied down. You're also threatening to double White's pawns on the c-file with ...Bxc3 if the time is right. Your long-term plan is to complete development with ...Nf6, ...d6 or ...d5, ...0-0, and then look for play on the f-file or queenside depending on how White sets up. The engine rates the position at +0.57 for White, but Black's practical results — 49.6% score across 192,914 Lichess games — show this is a very playable and combative choice.
White's Best Move: Bd2 and What Follows
The engine's top recommendation for White is Bd2. This unpins the knight and prepares to trade bishops. The main line continues Bd2 Nf6 e3 Bxc3 — White develops the bishop, accepts the exchange of your active bishop for their knight, and clamps down in the centre with e3. After ...Bxc3, White recaptures and gains the bishop pair while Black has disrupted White's pawn structure. Your compensation is that the c-file becomes half-open and White's queenside pawns can become targets. The engine evaluates the resulting position as slightly better for White (+0.57), but Black's practical results across 50,902 games at this move show White scoring only 48.7%, barely above equality.
