From the very first moves, White has pushed their centre pawns aggressively (e4 and d5), but your ...b5 has already started undermining the queenside. Stockfish evaluates this at -0.91, a clear advantage for Black — so you are clearly better here. The numbers back this up: across nearly 80,000 games from this exact position, Black wins 44.8% compared to White's 51.1%, and the draw rate is just 4.1%. While White still has a slight overall winning percentage in practice, the engine's cold assessment tells you that with accurate play, your position offers the more promising chances. The key is knowing which of White's moves to welcome and which ones to punish.
White's Most Popular Moves and What They Mean
White has several ways to continue, and each one demands a different response from you. Let's look at the main ones based on actual game statistics. The most common move, a4 (35,892 games), scores 53.4% for White — it's their best practical try. It immediately attacks your b5 pawn, challenging your queenside expansion. The engine's top choice, however, is Nf3 (8,248 games, 49.4% for White), which develops a piece and prepares to recapture on e4 after ...Nxe4. Nc3 (26,621 games) scores an even 50.0% for White. The other moves — b3 (48.4%), a3 (45.8%), and especially f4 (47.3%) — have worse track records for White. Your goal is to know the engine's preferred path and the mistakes White often makes.
The Engine's Best Answer: Nf3
The engine recommends Nf3, continuing with the line Nf3 Nf6 a4 Nxe4. After 5.Nf3, your best reply is 5...Nf6, developing with tempo and attacking the e4 pawn. White then typically plays 6.a4, and you capture with 6...Nxe4. At that point, you have won a pawn (the e4 pawn) in exchange for some central tension. This is the critical test: you need to be comfortable defending this pawn-up position while White tries to justify their compensation with active piece play. Practise this exact sequence in the drill so the natural reply 5...Nf6 becomes automatic.
Two Common White Mistakes to Punish
Two of White's less popular moves are actually inaccuracies that cost them real advantage. a3 (3,405 games, 45.8% for White) is an inaccuracy that loses roughly 0.6 pawns compared to the better move a4. White wastes a tempo — instead of challenging your b5 pawn immediately, they prepare to do so next move. You should respond as if they had played a4, but with an extra tempo in your favour. Even worse is f4 (258 games, 47.3% for White), an inaccuracy that loses about 1.0 pawns. This move weakens White's kingside and doesn't address the queenside tension at all. After f4, your queenside initiative becomes even stronger. Both of these are clear signals that White is uncertain in this position — punish them by staying active.
