Nilson Cardenas: The Bullet-Happy Candidate Master
From Weekend Warrior to Candidate Master
Nilson Cardenas, known on the chessboard as copanchess, is a FIDE Candidate Master who has never met a clock he did not like. His online journey started around 2010 with a modest Blitz rating, and over the years he turned that into a serious climb, reaching a Blitz peak of 2347 (2026-06-11). Along the way he rattled off 16 wins in a row, survived a 15 game losing streak, and kept queuing up for more.
His rating graph tells the story of a player who grinds, learns, and occasionally lets the clock get the best of him.
Opening Repertoire
Cardenas is a loyal 1.e4 soldier. When opponents answer with the Sicilian Defense, he reaches for the Alapin Variation more often than almost anything else. He also has a soft spot for the Caro-Kann Defense, the Scandinavian, and the French Advance, and he is not afraid to uncork the Bird Opening's Batavo Gambit when the mood strikes.
- As White, his Alapin lines have been tested in hundreds of Blitz battles.
- As Black, he favors the Najdorf and the Closed Sicilian.
- In Daily chess, the Blackburne Shilling Gambit has been a quiet weapon for him.
Rivalries and Rematches
Every great online career needs a nemesis, and for copanchess that nemesis is Nahun Gavarrete. The two have faced each other 113 times, a rivalry full of tough losses, occasional breakthroughs, and an endless appetite for rematches. Against Isaac Amaya, the story is sweeter: Cardenas holds a healthy lead with 41 wins. These repeated battles helped shape his stubborn, fight-to-the-end style.
Playing Style and Habits
If there is one word that describes Nilson Cardenas, it is bullet. He thrives in fast time controls, fires off checks early, and loves to keep both players low on time. His best hours are in the morning, especially around 09:00, when the tactics are crisp and the coffee is strong.
- He makes the first check in more than half of his games, often with the queen.
- His comeback rate is impressive: even after losing a piece, he still wins nearly 46% of the time.
- He has a clear edge with the White pieces and is not afraid to resign a lost cause and start again.
Cardenas is proof that persistence, a healthy opening repertoire, and a love for fast chess can carry a player a long way.
