Meet Juan Manuel Aranda, aka Fjal
Juan Manuel Aranda, known across the chess server as Fjal, is a FIDE Candidate Master with the stamina of a marathon runner and the curiosity of an opening explorer. His online record spans nearly 12,000 games, most of them played at bullet speed, and he has somehow made the wild Wiedenhagen-Beta Gambit feel like home.
Fjal's profile lists rapid as his preferred time control, and his rapid sample is gleaming: 7 wins, 3 losses and no draws. He is the rare player whose rapid adventures are 70% winning, including a perfect 3-0 in his beloved Czech Defense. Along the way, he pushed his blitz rating to 2491 (2026-08-13) and his bullet rating to 2543 (2024-08-18).
Opening Laboratory
With the white pieces, Fjal is famously loyal to 1.Nf3. Thousands of his games flow into the King's Indian Attack, and he has used the French Variation of that setup with real venom. When he wants chaos, he plays the Hungarian Opening's Wiedenhagen-Beta Gambit, a line he has tested more than 1,200 times. He has also played a variation called the Colle Rhamphorhynchus Variation over a thousand times, simply because the name is too good to ignore.
As Black, he prefers the Modern Defense, the Pirc Defense, and the Czech Defense. His results with the Czech Defense are especially strong, including a 53.23% win rate in blitz and a perfect 3-0 in rapid. A typical Fjal White game starts quietly before the pressure builds.
Marathon Man
Fjal's bullet volume is staggering. In June 2026 alone, he played 1,071 bullet games. That is roughly 36 games per day. His bullet rating has followed a volcanic path, and the chart below is the heartbeat of his online career.
He has streaks that define him: a 15-game winning streak, a 24-game losing streak, and a comeback rate of 82.92% that suggests he never stops believing. He reaches the endgame in 86.33% of his games, and his typical win runs about 75 moves. Fjal rarely does anything quickly.
He also wins 54.4% of his games when he delivers the first check, a handy habit. The queen is his most common checking piece, which makes sense for a player who loves to keep the pressure on.
Rivalries
No biography is complete without rivals. Fjal's longest running duel is against elenariskys, with 115 games and a healthy 79 wins for Fjal. Karl Tolentino, on the other hand, has been a thorn in his side, winning 56 of their 84 meetings. The two could probably write a book about each other's opening choices.
Other frequent dance partners include mijailtal06, user408632, and qvalda, all of whom have traded blows with Fjal dozens of times.
Beyond the Board
Fjal is at his sharpest around noon, when his win rate climbs above 55%. Sundays and Mondays are good days to challenge him, if you dare. He also has exactly one daily chess game on record, played in 2014, and he won it, which means his daily win rate is a flawless 100%.
Whether he is grinding out a 75-move victory or bleeding rating points in a tough afternoon session, Juan Manuel Aranda plays with unmistakable personality. Fjal is not a player who hides in theory. He is a player who makes the board his own.
