Junjun Cambelisa (nuj0617): Comeback Artist and Clock Warrior
Meet Junjun Cambelisa
Online chess has its archetypes: the cautious strategist, the gambit fanatic, the bullet flagger. Junjun Cambelisa, better known at the board as nuj0617, is somehow all three at once. Since a quiet debut in December 2023, Junjun has played more than 10,000 rated games, opened with 1.e4 the overwhelming majority of the time, checked with the queen over 11,000 times, and built a reputation on one very specific skill: winning games that looked lost. Reverse the "Jun" and you get "nuj", which might explain a style that regularly views the position from the wrong side first.
The Rise: Perfect Debut to Blitz Storm
The story opens like a heist movie. In December 2023, Junjun played exactly ten blitz games and won all ten, with the rating leaping from 567 to 951. Then came July 2024, a month of pure volume: 445 blitz games, 289 wins, and a climb from 996 to past 2100, powered by a 21-game winning streak that remains the personal best.
There have been dips and rebuilds since, the classic rhythm of a player treating the leaderboard like a treadmill set slightly too fast. A peak blitz rating of 2298 (2026-01-15) arrived in January 2026, following a rapid peak of 2238 the year before.
The Repertoire: Old Wine, Older Bottles
As White, Junjun keeps it honest and old school. The Center Game, heading straight for 1.e4 e5 2.d4 with the queen entering immediately, has produced a 60% blitz score. The Amazon Attack is the second weapon, a fitting name for someone whose most common checking piece is the queen by a landslide. The Bird Opening's Batavo Gambit rounds out the trio, with a mild Barnes dalliance thrown in for chaos value.
As Black, the signature is unmistakable: the Australian Defense has appeared in more than 1,300 games across formats, flanked by the Scandinavian Defense, the Blackburne Shilling Gambit, and the Amar Gambit. The best statistical friend is the Caro-Kann Defense, a 61.7% blitz weapon. The statistical frenemy is the Scotch Game, which sags to 38% in bullet. Nobody's perfect.
Rivals, Nemeses, and One Perfect Balance
Every grinder has a wall, and Junjun's is mralright666: 59 meetings, 16 wins, 43 losses, and presumably several quiet moments staring at the ceiling. Imtiaz Iqrum serves as the second wall at 13-23. On the sunnier side, georgesaleem has been a happy matchup at 30-12, and ijijijjijjjj split 59 games into a flawlessly symmetrical 29-29-1, the kind of record that belongs in a math textbook.
Style Report: The Numbers Behind the Grit
- Comeback rate of 88.78%: down does not mean done.
- Wins 50.68% of games even after dropping a piece, which is impressive and mildly insulting to the opponent.
- Reaches the endgame in about 72% of games, so pack a lunch.
- Resigns early 61% of the time when the position is finished, wasting no one's time, least of all their own.
- A tilt factor of just 14 and a one-sided loss rate of 1.38%: very hard to rattle, nearly impossible to flatten.
- Prime hours are noon and the afternoon, with a 56% score at 12:00. Avoid the midnight shift, where the win rate drops to a spooky 25%.
- Casual games suit the temperament better than rated ones, suggesting rating points weigh more than pawns.
- The flag is a lifestyle: 1,236 wins on time, but also 3,271 losses on time. Live by the clock, occasionally die by the clock.
The Daily Detour and Lasting Legacy
Amid all the speed, daily chess is the quiet showcase: a 17-6 record with zero draws and the strongest win rate of any pool, capped by a daily peak of 1009. Apparently when the clock grants hours instead of seconds, the queen checks simply get more thoughtful.
Whether in bullet, blitz, rapid, or daily, the online chess profile of Junjun Cambelisa tells the same story: relentless volume, an e4-first repertoire, and a comeback rate that turns lost positions into highlights. Opponents beware: in this story, the player who looks beaten tends to win.
