Pragg Ends Sindarov's 53-Game Unbeaten Run in Bucharest

Javokhir Sindarov’s 53-game unbeaten streak in classical chess is over. Praggnanandhaa ended it in Round 2 of the Super Chess Classic Romania on May 15, winning with the Black pieces from a position that had, moments earlier, looked genuinely dangerous for him. The result puts Pragg, Vincent Keymer, and Maxime Vachier-Lagrave in a three-way lead at 1.5/2 — and gives the rest of the Bucharest field something to study ahead of their own games against the world championship challenger.

The streak covered serious ground. Sindarov had gone unbeaten through eight rounds of the FIDE Grand Swiss, 14 games at the 2025 World Cup, 14 games at Tata Steel 2026, and all 14 rounds of the 2026 Candidates Tournament — the event that qualified him to face Gukesh Dommaraju for the world title. That’s nine months without a classical loss, against the best fields in the world. Pragg is the one who ended it.

The format

The Super Chess Classic Romania is the second event on the 2026 Grand Chess Tour calendar, running May 14–23 at the Museum of the National Bank of Romania in Bucharest’s Lipscani district. The format is a 10-player round-robin at 90 minutes for 40 moves, then 30 more minutes with a 30-second increment. Prize fund: $475,000, with $100,000 to the winner.

The full tour field: Fabiano Caruana, Alireza Firouzja, Wesley So, Maxime Vachier-Lagrave, Sindarov, Vincent Keymer, Anish Giri, Bogdan-Daniel Deac, and Praggnanandhaa. Levon Aronian withdrew due to health reasons and was replaced by Jorden van Foreest. Ian Nepomniachtchi joins as a wildcard.

Round 1: eight players, five draws

Every game in Round 1 was drawn — not without interest, but without winners. Sindarov played the King’s Indian Defense against Deac and drew cleanly. Pragg faced Firouzja and actually escaped: Firouzja held a significant advantage but played 35…Rbd8? and allowed simplification into a drawn rook endgame. Keymer and So played what Keymer described as “a full fight right from the start” — wild tactics and a time scramble, eventually split. Caruana and Van Foreest drew. Vachier-Lagrave and Giri reached an imbalanced position where Giri had an edge but let it go.

No separation. Everyone on 0.5 going into Round 2.

The game: Sindarov vs Praggnanandhaa, Round 2

Sindarov played White in the Italian Game, Giuoco Piano (C54). The theoretical move order leads to sharp positions, and Sindarov committed early: on move 11 he castled queenside rather than kingside, accepting an unbalanced structure in exchange for attacking chances against Black’s kingside.

The critical decision came on move 22. Sindarov played Nxh6+ — a knight sacrifice to rip open Black’s king position. The piece went. Black’s king was suddenly exposed, and for a stretch White had what looked like dangerous compensation. Pragg’s king ran: Kf8, then Ke8, then Kd8, pursued by White’s queen through moves 27–34 — Qh7+, Qg6+, Qf5+, Qg8+, Qg5+ — a relentless series of checks looking for the decisive blow.

It never came. On move 35, with the checks exhausted, White regrouped with Rce1 and Black stabilized. The position turned: Pragg’s pieces coordinated, Sindarov was down a piece without compensation. At move 36, Sindarov played Re3 — a 32-minute think on the wrong move. The resource was f4, which would have held a draw. After Re3, Pragg played Qg6, and White had nothing left. Sindarov resigned on move 42.

GM Rafael Leitao, watching the broadcast: “A model game for anyone who wants to improve defensive skills.” Pragg, asked about beating the world championship challenger: “I remembered more than he did, which is already enough.”

The queen checks through moves 29–34 (Qf5+, Qg6+, Qf5+, Qg6+, Qg8+, Qg5+) are the key sequence to watch. Sindarov was hunting for a way to keep the attack alive — each check is White looking for a king position where the tactics land. They never did. Once the checks ran out, Pragg’s extra material told.

The rest of Round 2

Three decisive results in one round is unusual at this level.

Keymer 1-0 Deac (Reti, 50 moves): Keymer won with 50.Re6!, his first Grand Chess Tour classical victory. He’d been building systematically since the opening — a central pawn break on move 16, patient maneuvering through the middle game, then Re6 to seal the endgame.

Firouzja 0-1 Vachier-Lagrave (Sicilian Najdorf, 60 moves): A long positional battle where both sides queened pawns late. MVL eventually won the queen endgame.

Caruana 1/2-1/2 Giri (Ruy Lopez, 38 moves): A Marshall Attack that was well prepared on both sides. Caruana holds the GCT tour standings lead from Warsaw.

Van Foreest 1/2-1/2 So (Berlin, 56 moves): White had the resource 19.Bh6!! — uncaptured throughout — as a positional threat that shaped the game without being taken. Drawn.

Standings after Round 2:

• Keymer, Praggnanandhaa, Vachier-Lagrave: 1.5/2
• Van Foreest, So, Caruana, Giri: 1.0/2
• Deac, Firouzja: 0.5/2
• Sindarov: 0.0/2

What this means for Sindarov

The timing matters. Sindarov arrived in Bucharest as the player coming off the best classical streak of recent memory and as the man scheduled to challenge Gukesh Dommaraju for the world title later this year. A loss doesn’t change that — the Candidates result is locked in, and one game doesn’t define a player who just went unbeaten for nine months.

But it’s the first meaningful data point that the streak was breakable. Pragg found the answer with the Black pieces, under pressure, when Sindarov was gambling with a piece sacrifice. That information is now in every opponent’s preparation file. Round 3 has Sindarov against Vachier-Lagrave — his first game since the loss, against a player who just beat Firouzja.

Meanwhile: Carlsen won in Malmö

Worth noting for context: the week before Bucharest, Magnus Carlsen played his first closed round-robin classical tournament outside Norway since 2023 — the TePe Sigeman Chess Tournament in Malmö, May 1–7. He and Arjun Erigaisi both finished on 5/7. The title went to tiebreaks, Erigaisi blundered his queen in a mutual time scramble in the Armageddon, and Carlsen won. He hadn’t played a classical tournament since Norway Chess in Stavanger in June 2025, nearly eleven months.
