Magnus Carlsen, Hikaru Nakamura, Alireza Firouzja and Denis Lazavik

The 2025 Speed Chess Championship has its final four. And it’s a blockbuster lineup.

With all quarterfinal matches complete, the semifinals are officially set: Magnus Carlsen vs. Denis Lazavik on one side of the bracket, and Hikaru Nakamura vs. Alireza Firouzja on the other. It’s a dream scenario for speed-chess fans: the reigning king of fast chess, the two most dominant online blitz players of the last decade, and a 19-year-old prodigy who just shocked the chess world.

While the finals in London on February 7–8, 2026, are still months away, the live semifinals promise one of the strongest four-player fields in the event’s history.

Lazavik Books A Spot Against Carlsen After Commanding Win Over Niemann

The most recent quarterfinal to finish delivered the last puzzle piece. GM Denis Lazavik, the Belarusian phenom who has quietly climbed into the global elite of blitz and bullet, defeated American GM Hans Niemann by a convincing 15.5–9.5 score. Across the three time-control segments—5+1, 3+1, and 1+1—Lazavik won every single one.

Entering the match, commentators IM Danny Rensch and IM Levy Rozman actually expected Niemann to hold the edge in the shorter formats, especially in the 3+1 segment. But the opposite happened. Lazavik not only kept up; he outplayed Niemann in nearly every phase of the match.

Quick Look at the Openings

Although this wasn’t a match defined by cutting-edge theory, several opening choices stood out:

  • Lazavik surprised Niemann with more Sicilians (1…c5) than usual, admitting afterward that he had specifically prepared the …Nh6 lines for this match.
  • In the 5+1 portion, Niemann repeatedly tested Lazavik’s Berlin-influenced setups with early central tension but struggled to make anything of the positions.
  • Lazavik’s most memorable win of the blitz section came from an English Opening that he converted into a kingside attack capped by a rook sacrifice—a reminder that he’s as dangerous in calm openings as in sharp ones.
  • In the bullet segment, Lazavik used the Grünfeld as White to score a miniature that symbolized the overall match: fast, precise, and unforgiving.

With nerves shaking off after a few missed chances early on, Lazavik reeled off streaks of clean wins. His composure was the story of the day. Even Niemann admitted afterward that he simply “didn’t play great,” while Lazavik insisted that he doesn’t consider himself stronger—just better on the day.

The result sends Lazavik to face Magnus Carlsen, a matchup made even more interesting because Lazavik beat Carlsen at the 2024 World Rapid Championship. Carlsen is still the favorite, but now he’ll be preparing for an opponent he knows is capable of real damage.

Carlsen Advances Smoothly On His Side Of The Bracket

The top seed and most recognizable name in speed chess, Magnus Carlsen, reached the semifinals after taking down Mexico’s GM José Martínez in the Round of 16 and then defeating GM Fabiano Caruana 14.5–7.5 in the quarters.

Carlsen’s style in this year’s SCC has been unmistakably confident: stable openings, low-risk positions, and the typical grinding that forces mistakes from even the world’s best. Whether he chooses his trusted 1…e5 against Lazavik or prepares something new—as Lazavik did against Niemann—will be among the biggest storylines heading into the semifinal.

Carlsen is chasing another Speed Chess Championship crown to cap a remarkable stretch of dominance in fast time controls. But of all opponents he could have faced, Lazavik might be the most unpredictable.

Nakamura vs. Firouzja: A Clash Of Online Titans

On the other side of the bracket, fans get the matchup many have been waiting for: Hikaru Nakamura vs. Alireza Firouzja.

This pairing pits:

  • The most successful online blitz player ever (Nakamura)
    against
  • The most dangerous younger generation superstar in fast chess (Firouzja).

Nakamura’s Road to the Semis

Nakamura defeated Vietnam’s Lê Quang Liêm in a tightly contested match before overcoming Wesley So 11–10 in the quarterfinals. His play has been classic Hikaru—hyper-accurate calculation mixed with relentless practical decision-making.

Nakamura’s opening choices this year have been crisp and flexible: using both 1.e4 and 1.d4, and mixing the Nimzo-Indian, Queen’s Gambit Declined, and even occasional King’s Indian setups. His ability to shift gears based on format (blitz vs. bullet) remains arguably the best in the world.

Firouzja’s Path So Far

Firouzja has looked equally convincing, taking out Lê Tuấn Minh in the first round and then defeating Ian Nepomniachtchi 19–9 in one of the most one-sided matches of the event. Firouzja’s trademark sharpness has been on full display, especially in the 3+1 and 1+1 segments where his ability to convert initiative into checkmate is unmatched.

Openings like the Sicilian Najdorf, Ruy Lopez, and aggressive King’s Indian setups have given him dynamic positions where he thrives most. Against Nakamura, though, every opening will be tested to its limit.

The Nakamura–Firouzja semifinal promises a contrast of styles: Nakamura’s stability and experience against Firouzja’s creativity and energy. Both are former Speed Chess Championship finalists, and both believe they can win the whole thing.

A Historic Lineup For London

The semifinals and finals will be played live in London on February 7–8, 2026. For the first time, all segments will be longer:

  • 5+1 → 90 minutes
  • 3+1 → 60 minutes
  • 1+1 → 30 minutes

With $250,000 in total prizes and three Esports World Cup qualification spots on the line, motivation could not be higher.
