Fast Chess Philosopher
Ruben Felgaer, known online as rfelgaer, holds the Grandmaster title, but his online life is pure Blitz fuel. From 2016 through 2026, his account shows a player who truly prefers the fast lane: thousands of rated Blitz games, a long winning streak of 9, and a Blitz peak that scratches at the 3000 ceiling. His online peak reads 2994 (2026-08-30), a number he touched in late August 2026 after years of steady online pressure.
He may be a Grandmaster by title, but his data says he is happiest when the clock is hunting.
paints that story nicely.Language of the Openings
Ruben is not shy about repeating openings; he likes what he likes. With Black, he leans on the Czech Defense as a reliable fighting weapon, playing it 378 times in Blitz. With White, he enjoys feeding the Sicilian Defense in many forms, including Dragon and Najdorf plans, and he has especially strong numbers against the French Defense. His Blitz opening results show a 63% win rate in 93 French Defense games, which is a good sign for any opponent preparing something less familiar.
He also likes targets that keep pieces on the table near. His average first capture lands around move 7, and his games often go into a deep, scrappy middle game before he starts changing the wood count.
gives a broad view of the patterns he leans on most.Rivalry Status
Every fast player needs someone who forces them to work, and for Ruben, that someone is Alan Pichot. Platy3 leads their meetings in 60 Blitz games, with 31 wins and 16 losses from Ruben's perspective, plus more shared draws. It is a regular fixture by online standards, and it seems safe to guess that both players know what to expect from each other's opening habits.
Blood, Guts and Clocks
Ruben's statistical personality can be called generous in some places. His comeback rate soars near 89.5%, and he wins games 43.9% of the time after losing a piece. He also values not leaving early; his early resignation rate sits under one percent, so the games run long even in Blitz. His average winning game clocks in at about 83 moves, a heavy workload for an online bullet blitz specialist.
The record even includes a 17-game losing streak, but the same dataset shows he kept coming back, winning bundles against lower-rated players and pushing hardest in the early morning: his statistical best time is 05:00, so coffee before knights works.
