Indian junior chess continues to produce players capable of competing on the national and international stage at remarkably young ages. At the 39th National Under-11 Open Chess Championship in Mangaluru, FM Sarbartho Mani added another major achievement to an already impressive young career.
Representing West Bengal, Mani entered the championship as the second seed with a rating of 2273. The field included several of India’s strongest players in the age category, including FM Advik Amit Agrawal, Nidhish Shyamal, CM Sattwik Swain, Oishik Mondal and CM Divith Reddy Adulla.
The title is particularly significant because Mani had already established himself internationally. In 2025, he won the FIDE World Cadets Cup U10 and the FIDE World Cup U10, demonstrating that his progress was not limited to domestic competition. FIDE’s records also show him finishing second in the Open U10 section of the 2026 FIDE World Cup Under 10.
Now, he has added the National Under-11 title to that growing résumé.
Top 5 Games
Game 1 — Round 5 vs Aadwik Abhinav Krishna
This is one of the most instructive games of Sarbartho’s championship because the decisive work came long after the opening. Mani began with a flexible Réti setup and gradually transformed the position into a Queen’s Gambit-type structure.
After 16…c4, Black gained queenside space, but Mani responded patiently rather than rushing into complications. The sequence 25.Bd2 c3 26.bxc3 bxc3 27.Bxc3 removed the dangerous passed pawn and forced the queens off with 28…Qxf2+ 29.Kxf2. From there, the game became a technical battle.
Mani’s king became an active piece, while his rooks repeatedly invaded the seventh and eighth ranks. The sequence 37.Rb5, 38.Rxd5 and 43.f6 showed excellent coordination between his rook and advancing pawns. Black’s a-pawn created counterplay, but Mani correctly prioritised activity and kept checking the king.
The final phase was particularly impressive: after 68.f7 Re2, instead of automatically promoting to a queen, Mani played 69.f8=N+!, an underpromotion that came with check and immediately ended Black’s resistance after 70.Bg7+.
This was a game of patience, active pieces and precise calculation in a long endgame.
Lesson :
In difficult endgames, active pieces and accurate calculation matter more than material alone; keep improving your position until the win appears
Game 2 — Round 7 vs Devansh Keshri
This game demonstrates an important practical skill: playing against the clock without losing control of the position. Mani built a comfortable position from a Queen’s Indian/Réti-style setup, placing his pieces actively and preparing the central break e4.
The move 18.Bxa6 was a useful decision, removing a pawn and forcing Black’s rook into a less comfortable position.
The critical phase arrived after 25.e4 fxe4 26.fxe4. Mani’s central pawns became powerful, while Black’s clock collapsed. After 27.Bxd4, White had simplified the position while retaining the initiative. The sequence 29.Ne3, 30.Nc4 and 31.Qxc4 removed Black’s remaining active knight and left Mani with a very favourable material and positional balance.
Black’s clock tells an important story: by move 34, he had little more than a minute. Mani did not panic or try to force an immediate tactical finish. Instead, he continued making useful moves: 35.Rd7+, 36.Qxc5 and 37.Bd4. Even when Black generated checks with …Qf4+, Mani kept his king safe and maintained control.
The game ended after 39.Kg1, with Black unable to continue.
Lesson:
When your opponent is short of time, stay accurate and improve your position; pressure works best when you don’t rush.
Game 3 — Round 8 vs Varchas Krishna Jayaraman
This was perhaps Mani’s most tactically interesting victory. The game began as a sharp Sicilian, and White immediately chose an ambitious route with 6.Ndb5 and 7.Nd6+, forcing the black king to e7. Instead of becoming defensive, Mani responded actively with 8…e5 and gradually challenged White’s advanced pieces.
The exchange on f5 and subsequent 14…Bxc3 created structural weaknesses for White, but Mani’s real strength was his ability to coordinate his queen, rook and knight against an exposed king. After 19.Rb4 Ned5 20.Rh4 Nxe3 21.fxe3, White had attacking intentions, but the exposed kingside also gave Mani targets.
The sequence beginning with 25…Qxc3 was particularly important. Mani’s queen became extremely active, entering with checks and forcing White’s pieces into passive defensive positions. White’s rook repeatedly moved between g3 and h3, while Mani’s knight manoeuvred between e4 and g5, creating a persistent net.
The final combination was elegant: 46…Nxg1! removed the rook, followed by 47.Rxg1 Qxe3 and 48.Bxc4 Qf3+. Mani emerged with decisive material and positional advantages and converted without difficulty. It was a strong example of counterattack beating an overextended attack.
Lesson:
An exposed king is not automatically a weakness for one side; active counterplay can turn the opponent’s attack against them
Game 4 — Round 9 vs FM Advik Amit Agrawal
This was arguably Mani’s most important game from a competitive perspective. He faced FM Advik Amit Agrawal, the higher-rated opponent and one of the tournament’s leading contenders. The game began with a King’s Indian-style setup, with both players developing naturally before the position became tactically sharp.
The critical sequence started with 9.d5 Nxd5 10.cxd5 Bxc3. White immediately exploited the tactical possibilities with 11.Bh6, and after 12.Nxe5 Bxe5, Mani continued with 13.Bxf8 Bxa1 14.Bxe7 Qxe7 15.Qxa1. The resulting position was materially unusual but balanced by active pieces and structural considerations.
Mani then played actively with 16.Qc3 and 17.Re1, while Black countered with …c6 and …b5. The exchange sequence beginning with 21.Rxc8+ simplified the position further. After 23.Bxb7 Qxb7, the game entered a quieter phase.
What is especially interesting is what happened next: neither player was willing to create unnecessary risk. From move 25 onward, the kings moved back and forth between h2/g1 and h7/g8. With the tournament situation in mind, both players accepted the draw after 30…Kg8.
For Mani, holding the second seed to a draw was a valuable result and demonstrated mature tournament judgment.
Lesson:
Strong tournament chess is not always about winning; knowing when to neutralise a dangerous opponent is also a competitive skill.
Game 5 — Round 11 vs Devanarayanan Kalliyath
The final-round game is the perfect closing game for this article because Mani finished his championship with a confident and technically controlled victory.
The opening was quiet: Mani developed through a Réti structure with Nf3, e3, c4, Nc3 and b3 before exchanging on d5. Rather than forcing the position, he gradually prepared the central break with 15.e4. After 15…dxe4 16.Nxe4, White had active pieces and Black was already spending considerable time.
The critical tactical phase began with 18.d5. Black tried to simplify with 18…Nxe4, but Mani calculated the exchange sequence accurately: 19.Rxe4 Rxe4 20.Bxe4. After 21.h3, he also eliminated the dangerous knight with 22.hxg4.
The most instructive moment came at 25.g5. Black’s bishop moved to e5, and Mani immediately opened the f-file with 26.gxf6. Black responded 26…Bxd4, apparently winning the queen, but Mani had seen the tactical point: 27.fxe7, and the pawn reached e7 with decisive consequences.
The game ended immediately after Black could no longer prevent the pawn from becoming a major threat.
It was an excellent example of creating a passed pawn while simultaneously exploiting tactical weaknesses.
Lesson:
Passed pawns become strongest when they advance with tempo; always look for tactical opportunities created by promotion threats.
Performance
Mani’s championship victory comes after a rapid rise through India’s junior chess ranks. His trajectory has been particularly striking because he has consistently performed against strong opposition rather than relying solely on age-group events.
His international results provide important context. In 2025, Sarbartho Mani won the Under-10 Open title at the FIDE World Cup in Batumi, Georgia. He followed that achievement with a bronze medal at the World Cadet Chess Championship in Almaty, Kazakhstan, scoring 8½/11. These two podium finishes established him as one of India’s leading young talents on the international stage.
He also finished second in the Open U10 section of the 2026 FIDE World Cup Under-10 with 8½/11, behind Ulan Rizat, while compatriot Sattwik Swain finished third on the same score.
That makes the National Under-11 title a logical continuation of his development rather than an isolated result.
There is also an interesting historical thread. Mani finished fifth in the 2025 National Under-11 Championship with 8½/11, behind champion Aarit Kapil.
A year later, he returned to the same championship and went all the way.
That is perhaps the most important part of this story.
He didn’t simply arrive as a champion. He came back and improved.
Conclusion
Sarbartho Mani’s National Under-11 victory is another milestone in the journey of one of India’s most promising young players.
From his early success at the national level to becoming a World Cadets champion and now a National Under-11 champion, Mani’s progress reflects a combination of competitive experience, strong tournament exposure and an ability to perform against his peers at the highest level.
But at ten years old, the National title should be viewed as another chapter, not the destination.
For Indian chess followers, the more interesting question is what comes next.
Can Mani continue converting his junior success into strong performances in open tournaments? Can he make the transition from being one of India’s strongest youngsters to becoming an International Master and eventually a Grandmaster?
For now, one thing is certain:
FM Sarbartho Mani is the 39th National Under-11 Open Champion — and his chess journey is only beginning.
