How to beat the Hungarian Opening (1.g3)

1.g3: White fianchettoes the king's bishop first and waits to see your set-up, often heading for a King's Indian Attack, an English or a Catalan. It turned up in 300 games of our sample, and it was one of the friendlier first moves for the top titled players to face: they scored 68% as Black against it in 211 games, above their 62% average as Black.

Three plans that work

1. Start with 1...Nf6

1...Nf6 keeps everything flexible: ...d5, ...g6 or ...e5 can come next, depending on what White does. Lichess calls 1.g3 Nf6 the Indian Defense line, and it was the titled players' best common reply in our sample: 78% as Black in 49 games.

2. Claim the centre with ...d5, ...c5 and ...e5

White's set-up is slow, so take the space. With ...d5, ...c5, ...Nc6 and ...e5 White ends up in a King's Indian Attack set-up while you own the centre. The games Lichess files under the plain Hungarian Opening name (replies without their own sub-name) scored 71% for Black in 69 games.

3. Don't just mirror it with 1...g6

Copying White with 1...g6 (the Symmetrical Variation) was the titled players' weakest common reply: 56% as Black in 36 games. The quiet 1...d5 2.Bg2 c6 Slav Formation was below average too (60% in 29). Against a waiting move, the active centre plans did better.

A line to play

1.g3 Nf6 2.Bg2 d5 3.Nf3 c5 4.O-O Nc6 5.d3 e5 6.e4 d4

The pitfall

Forgetting the g2 bishop. It stares down the long diagonal at d5, b7 and a8: when White hits d5 with c4 or e4, keep it protected or push past with ...d4, and think twice before ...b6 or moving the c6 knight while your a8 rook is still on that diagonal.
