The Man Behind the Clock
Juan David Becerra Morales, known to his online rivals as becemix, is a FIDE Master from Colombia with a clear priority: blitz, blitz, and a little more blitz. Where many titled players hide their time in slow classical events, Juan found his home in the 3-minute thunderdome, stacking up thousands of decisive games and an official blitz peak of 2671.
He is not a casual visitor either. His longest winning streak stretches to 13 straight games, and his love of the battle is visible in the data: wins come after roughly 79 moves, losses last about 79 too, and he fights deep into the endgame in over 80% of his matches. This is a player who routinely asks you to keep playing.
The Alapin Missionary
If you get paired against becemix, you can prepare for one specific kind of punishment: the Sicilian Defense: Alapin Variation. He has faced it nearly 350 times across blitz and bullet, and he scores about 58% with it, using it as his favorite scalpel against the Sicilian. When he wants a bit more chaos, he reaches for the Bird Opening and its Dutch Variation lines, an old weapon he's played with respectable success.
He also respects the classics at the board: the Caro-Kann Defense, the French Defense, and the occasional Blackburne Shilling Gambit appear in his opening directory. But the Alapin and the Bird are the flags he plants.
Rivalries and Revenge
No profile is complete without its nemeses. The one player who gives him the worst headaches is Joshua Daniel Ruiz Castillo, who has beaten him 13 times in 22 meetings. Then there is Edgar Karagyozian, a much closer battle: 10 wins for becemix, 8 for his rival, and 3 draws. And in the "run while you can" column, he has a complete 12-0 career record against laucayon, so maybe that opponent should simply stop accepting the rematch.
The Comeback Specialist
Statistics describe a player who refuses to leave the building. He wins nearly 45% of games even after losing a piece, and his comeback rate sits high above 80%. This may also explain his tilt factor: losing streaks can arrive, but so do winning streaks. He is most dangerous at 07:00 and likes to play his best on Saturday afternoons, when the knights, rooks, and queens are all awake.
His style is a little wild: a one-sided loss is rare, his games last long, and even after surrendering the center he trusts his endgame instinct. That makes him exhausting, resilient, and occasionally brilliant, sometimes all in the same match.
The Full Picture
Since 2018, becemix climbed from a solid online blitz regular to a true bullet specialist's nightmare. He hit 2671 (2026-03-25) in blitz and 2695 (2026-03-11) in bullet, proving that his clock management keeps up with his ever-sharp tactics.
His rating has traveled a winding path, but the trend is clear: this is a player who improves in bursts and never quiet down.
