King's Gambit Accepted: MacLeod Defense with Bc4 – Playing as Black
You've reached a key crossroads in the King's Gambit Accepted. After 1.e4 e5 2.f4 exf4 3.Nf3 Nc6 4.Bc4, you pushed g5 — the MacLeod Defense. This is a sharp, old-school line where Black grabs space on the kingside and challenges White's knight immediately. The engine likes your position: Stockfish rates it -0.75, a clear edge for Black. That means you are already clearly better here if you know what to do. Statistically, though, White still wins 51.7% of games from this position — so there's plenty of work left. The drill below will train you to handle White's most popular and best replies.

By playing 4...g5, you're doing something direct: you've seized space on the kingside and threatened to kick the f3-knight with ...g4. White's light-squared bishop on c4 eyes f7, but your ...g5 advance gives you a tempo and a grip on the f4 pawn. The engine confirms this is a healthy choice. From Black's perspective, the position scores 45.9% wins — impressive given how aggressive White's setup is. Your plan is simple: keep the extra pawn on f4, chase the knight, and prepare to castle kingside or counter in the centre once White commits.
White's Best Move: d4
The engine's top recommendation for White is 5.d4. This central push aims to open lines and ignore your kingside thrust. The idea is to follow up with 6.g4, attacking your pawn chain, and then 7.O-O after 7...gxf3 — sacrificing the knight for long-term attacking chances. The stats show 5.d4 is played in 70,166 games, and White scores 50.5% with it — the lowest winning percentage among the most-played moves. That tells you White's best try still leaves you with excellent practical chances. If your opponent plays 5.d4, stay calm, grab the knight when it's offered, and defend accurately.
Punish White's Most Common Mistake
The most popular move here is 5.O-O, played 133,985 times — nearly half of all games. But the engine flags it as an inaccuracy that loses roughly 0.6 pawns compared to the best move 5.d4. Your reply is simple: kick the knight with 5...g4. Now White's knight has nowhere great to go, and you keep your extra pawn on f4. Two other common inaccuracies are 5.c3 (loses ~0.7 pawns) and 5.Nc3 (loses ~0.8 pawns). Against both, the same principled push ...g4 gains a tempo and leaves White's pieces awkwardly placed. Whenever White wastes a move on something other than central action, punish them by advancing your kingside pawn.

Despite the engine saying Black is clearly better, White still wins 51.7% of the time, Black wins 45.9%, and only 2.4% end in draws. The King's Gambit is a razor-sharp opening where one slip can flip the evaluation. Your -0.75 advantage is real, but it requires precise moves — especially if White plays the engine's 5.d4 and sacrifices a knight. Use the drill below to practice the key responses until they're automatic. If you can navigate the first few moves accurately, the lasting advantage the engine promises is yours to convert.
