Italian Game: Hungarian Defense with c3 – How to Play as Black

On move four, White has built a nice centre with c3 while you've chosen a solid development pattern with Nf6. The engine's top move for White is 5.d4 — attacking the centre head-on — and the critical line runs 5...Nxe4 6.dxe5 d6. Black gives up the e5-pawn temporarily but aims to win it back with active piece play. Your knight on e4 is a temporary outpost, and after 6...d6 the d-pawn attacks the e5-pawn while clearing the c8-h3 diagonal for the light-squared bishop. This is fighting chess: you're not just defending, you're counterattacking from a safe position. The statistics show that even in the main line with 5.d4, White scores only 46.6% — meaning Black outplays White from here more often than theory would suggest.

White has several reasonable-looking options, and you need to know how to react to each one. Here are the most common moves and what you should expect: 5.d3 (319,475 games) is by far the most popular, a safe developing move that shores up e4. White scores 48.4% here — still below average for White. You can continue with natural development like 5...d6 or 5...O-O, keeping the pressure on e4. 5.d4 (212,458 games) is the engine's first choice and the most principled — White strikes the centre immediately. As shown above, capturing the pawn with 5...Nxe4 is the typical reply. 5.O-O (77,026 games) is actually an inaccuracy according to Stockfish, losing about 0.6 pawns. White should have played 5.d3 instead. You can calmly develop and enjoy a slightly better position.

The engine identifies several common White moves that are outright mistakes. Knowing these gives you a chance to seize an advantage early: 5.Ng5 (29,043 games) is a mistake that loses about 1.2 pawns. White tries a cheap threat against f7, but it's easily parried. After 5...d5 (attacking the bishop), White's knight has no good square and your centre is solid. 5.Qb3 (28,229 games) is even worse — a mistake costing about 1.3 pawns. White attacks f7 and the b7-pawn, but you can defend with 5...Na5 or 5...O-O and emerge with a clear plus. 5.O-O as mentioned is not a full mistake but an inaccuracy. If you see any of these moves from White, trust the engine: you have a real advantage to work with.

The statistics across 735,989 games paint a clear picture. White wins only 46.9% of the time — well below the usual 52-54% White scoring rate. Black wins 49.2%, meaning this is one of those rare opening positions where the second player is the favourite in practice. The draw rate is just 3.8%, reflecting that this is a fighting position where both sides play for a win. If White plays accurately with 5.d4 or 5.d3, the position remains close to equality. But many White players underestimate the Hungarian Defense and make one of the punishable mistakes — and when they do, the engine says you're clearly better. Your job is to know which White moves to welcome and which to fear (spoiler: there are almost none to fear).
