Sam Sevian is a classical, principled opening player. He doesn’t hide from theory in offbeat sidelines — he plays the big main lines and backs his preparation to hold up in the sharpest positions chess has to offer. Below is his core repertoire, drawn from his most-played openings, with a couple of verified tabiya positions to show where the battles begin. (Repertoires evolve; treat this as his signature terrain rather than a fixed script.)
As White: 1.e4, straight down the main roads
Sevian is an 1.e4 player who welcomes the game’s biggest theoretical fights rather than sidestepping them.
The Open Sicilian
When opponents answer with the Sicilian Defense, Sevian heads into the Open Sicilian — the most ambitious, double-edged way to meet it. Against the Najdorf in particular he favors the English Attack setup, a sharp plan of Be3, f3, Qd2 and a pawn storm against the enemy king. These are among the most heavily-analyzed positions in all of chess, and choosing to fight here says a lot: he trusts his memory and his nerve in complications that many players actively avoid.
The Ruy Lopez
His other great 1.e4 workhorse is the Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3.Bb5). This is the ultimate “understanding” opening — long-term pressure, subtle maneuvering, and rich middlegames where a small structural edge can be nursed for the whole game. It fits Sevian’s technical, patient style perfectly: get a sound position, keep the tension, and grind.
As Black vs 1.e4: the Italian and classical e5 play
With the black pieces against 1.e4, Sevian is comfortable in classical 1…e5 territory. A regular guest is the Italian Game — specifically the Giuoco Piano (3.Bc4 Bc5), the quiet-but-deep version where both sides build slowly before the real fight begins. It’s an opening of maneuvering and structure rather than early fireworks, which again suits a player who likes to out-play opponents in the long middlegame. The Ruy Lopez complex appears on his side of the board as well; he understands these e5 structures from both colors.
As Black vs 1.c4: the King’s English
Against the English Opening (1.c4), Sevian meets it head-on with the King’s English — replying 1…e5 to grab central space and mirror White’s flank strategy. It’s the most principled, combative way to handle the English, turning White’s flexible setup into a genuine fight for the center rather than letting White dictate a quiet game.
Why the classical main lines?
There’s a strategic logic to why a player builds a repertoire like this. Offbeat sidelines and gambits can win quick points against under-prepared opponents, but at the very top everyone has seen everything — the surprise value evaporates, and you’re left needing genuine, well-founded positions. Sevian’s answer is to invest in the openings with the deepest theory and the richest middlegames, then out-work and out-understand opponents inside them. It’s a higher-effort, higher-ceiling approach: more to memorize, but far more reliable when the opposition is elite.
It also plays to his temperament. Because these classical openings so often produce long, maneuvering struggles, they hand the game to exactly the phase where he’s strongest — the slow squeeze, the technical endgame, the war of small advantages. In other words, his opening choices aren’t separate from his style; they’re the setup for it, funneling games toward the kind of positions he most wants to play.
The theme tying it together
Look across the whole repertoire and a clear identity emerges: classical, central, and principled. Sevian plays the openings the world’s best have trusted for a century — the Open Sicilian, the Ruy Lopez, the Italian, the King’s English — because they lead to the rich, understanding-based middlegames where his preparation and technique shine. He’s not looking for a cheap trick out of the opening; he’s looking for a sound position he can outplay you from.
That’s exactly why his opening choices and his playing style are so tightly linked — the lines feed the grind. To see the repertoire translate into results, browse his best games.
