Introduction
Luis Fernando Corredor, who plays online as ETMasterL, is a FIDE Candidate Master with an almost bottomless appetite for online chess. His preferred time control is Blitz, yet his bullet history is a mountain of activity that many players would find exhausting just to read about.
Career Highlights
Between 2019 and 2026, ETMasterL turned the online chess world into his training ground. He has played nearly 29,000 tracked games, built a longest winning streak of 15, and reached a bullet peak of 2726 (2026-09-16) while climbing to 2533 (2024-06-14) in Blitz. His comeback rate of 90% shows that giving him an early advantage is rarely safe.
Playing Style and Openings
ETMasterL is comfortable in both quiet structures and chaotic tactical fights. As Black he leans heavily on the Sicilian Defense, and inside that world he has found real success with the Najdorf Variation. In Blitz he also has a soft spot for the tricky Blackburne Shilling Gambit, where he scores a solid 63%.
His games tend to go deep. Decisive battles often stretch past 75 moves, and he reaches an endgame in more than 83% of his games. He is also aggressive with checks, with the queen doing most of the heavy checking work.
Familiar Rivals
Online success comes with recurring rivals. Nobody has faced ETMasterL more than ugetting, with 106 meetings and a razor-thin overall record in his favor. roberto petrulli has appeared 70 times, while Khoa Bui has traded blows with him in 57 games.
A Quirky Competitor
He is happiest at the board in the morning, with his best results coming at 08:00. He wins 54% of his games with the white pieces and nearly 50% with Black. Against lower-rated players he pounces at a 63% rate, while he still manages to win about 29% against higher-rated opposition. He can lose 13 in a row, but he can also rattle off 15 straight wins. That unpredictability makes every ETMasterL game worth watching.
