Wei Yi’s opening repertoire is a perfect match for his personality: classical, principled, and above all combative. He’s not a gimmick player looking to trick opponents in the first ten moves — he heads for the game’s richest, most-analyzed main roads and backs his understanding and calculation to win the fight from there. In fact, his choices are so reminiscent of a young Garry Kasparov that the comparison comes up again and again. Here’s the tour.
As Black against 1.e4: the Najdorf Sicilian
Wei Yi’s calling card with the black pieces is the Najdorf Sicilian — the sharpest, most uncompromising answer to 1.e4 in all of chess, and famously Kasparov’s own weapon of choice. The Najdorf (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6) creates immediate imbalance: Black concedes nothing, fights for the initiative, and invites the kind of double-edged battle where both sides attack. It’s a demanding, theory-heavy choice that only players who trust their calculation will take on — which is exactly why it suits Wei Yi so well.
As Black against 1.d4: the Grünfeld and King’s Indian
Against the queen’s pawn, Wei Yi keeps the fighting spirit alive with two of the most dynamic defenses in the book — again, the same pair a young Kasparov leaned on.
The Grünfeld Defense (1.d4 Nf6 2.c4 g6 3.Nc3 d5) is a hypermodern gem: Black lets White build a big pawn center, then attacks it with pieces and timely pawn breaks. It leads to concrete, tactical positions where accurate calculation decides the day — right in Wei Yi’s wheelhouse.
The King’s Indian Defense (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6) is the other pillar — arguably the ultimate winning-attempt weapon for Black. Here Black also cedes the center, then strikes back with a thunderous kingside pawn storm, often racing to mate White’s king while White pushes on the other wing. Few openings promise sharper, more attacking chess, and few players are better equipped to handle the complications.

As White: a classical 1.e4
With the white pieces, Wei Yi is a 1.e4 player at heart, heading for the oldest and richest main roads. He’s comfortable in the deeply strategic Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3.Bb5), where tiny structural nuances build into long-term pressure — a great fit for his maturing technical side.
He’s also shown a taste for a razor-sharp Italian Game, injecting fresh attacking ideas into an opening many players treat as quiet. And when opponents meet him with the Sicilian, he answers in kind with the principled Open Sicilian, diving into exactly the kind of mutual-attack positions he loves from the black side — the same family of positions that produced his famous 2015 “Immortal” against Lázaro Bruzón.
A repertoire that grew up with him
One underrated thing about Wei Yi’s openings is how they’ve matured alongside his game. The teenage prodigy who dazzled with tactics leaned hard on the sharpest lines to force complications; the world top-10 player he’s become has broadened his choices and deepened his understanding, so that the same openings now serve a more complete style. The Najdorf is still a fighting weapon, but he can also use its quieter branches to outplay opponents in the endgame; his 1.e4 as White can produce a king hunt or a patient positional squeeze depending on what the game demands. The repertoire didn’t change its character — it’s still built for the fight — but it gained the flexibility that separates an exciting junior from a genuine elite grandmaster.
The theme tying it all together
Notice the pattern: every one of Wei Yi’s core openings is a fighting opening. The Najdorf, the Grünfeld, and the King’s Indian are three of the most combative, winning-oriented defenses in existence, and as White he plays the classical main lines rather than sidestepping the theory. There’s no drawing weapon hiding in this repertoire — it’s built, top to bottom, by a player who wants to outplay opponents in rich, double-edged positions rather than neutralize them. It’s the repertoire of an attacker, and it’s a big part of why watching Wei Yi is such a treat.
