The Vienna: King's Gambit: Bc5 — You're Already Winning

Your big edge comes from a simple idea: you've grabbed a pawn on e5 while Black's knight on f6 is under attack, and Black's bishop on c5 is doing nothing to help defend the centre. After 4.fxe5, Black's knight must move. The best move is Ng8, retreating all the way back — humiliating but necessary. In over 55,000 games, that's what Black played most often, and you still scored 66.4% against it. Your plan is straightforward: develop quickly with d4 (attacking the bishop) and Qh5, putting maximum pressure on Black's cramped position. You're fighting to maintain your pawn-structure advantage and your lead in development, while Black struggles to get pieces out.

If you want a concrete path to follow, the engine recommends this line after 4.fxe5: Ng8 d4 Bb4 Qh5. Let's break that down. First, you push d4, kicking the bishop. When it retreats to b4, you bring your queen to h5 with a threat. This keeps Black tangled up — the knight on g8 and bishop on b4 are both awkward. The d4 pawn controls the centre beautifully, and your queen on h5 eyes the f7 square and prevents Black from castling easily. You don't need to memorise everything; the drill below will let you practise these ideas against the engine.

Across 112,881 games from this exact position, your results as White are outstanding. Here's how White scores against each of Black's replies: - Ng8 (the best move, played 55,251 times): you win 66.4% - Nxe4 (22,402 games): you win 63.0% — not bad, but it's actually an inaccuracy - Bxg1 (11,322 games): you win 62.0% - Ng4 (9,782 games): you win 72.4% — this is a real mistake you can punish - Bf2+ (3,530 games): you win 73.9% — also a mistake - O-O (3,190 games): you win 67.7% The lesson is clear: no matter what Black plays, you are the favourite. But some replies are better for you than others — and two of them are outright errors you can exploit.

The computer identifies three Black moves that make your life even easier. Nxe4 is an inaccuracy, losing about 0.7 pawns of advantage compared to the best move Ng8. You shouldn't panic if Black grabs the knight — just stay calm and keep developing, because your position is still superb. Ng4 is a real mistake, costing Black roughly 1.5 pawns. The knight on g4 looks active but is misplaced — you can gain time by chasing it away with h3 or simply play d4 with a big centre. Bf2+ is the worst of the bunch, losing about 2.1 pawns. This check achieves nothing: you move the king to e2 or block with the knight, and Black has wasted a tempo while your position keeps getting stronger. If your opponent plays any of these, you have a clear path to convert your near-winning advantage.
