Ruben Felgaer - The Grandmaster with a Blitzing Finesse

Meet Ruben Felgaer, known in the chess world simply as rfelgaer. A Grandmaster titleholder recognized by FIDE, Ruben is a force to be reckoned with on the 64 squares. His chess career is like a rollercoaster ride through lightning-fast blitz battles and gritty endgames that could tire out even the most seasoned grandmasters.

Rating Rocket and Style

Ruben’s peak blitz rating skyrocketed to an astonishing 2935 in early 2025, showcasing his exceptional lightning chess skills. He plays with a calculated aggression, boasting a comeback rate of over 91%, which means if you think you’re winning after taking a piece, think again—this grandmaster loves to turn tables!

His games are often marathons rather than sprints, averaging around 81 moves per win. Clearly, patience and endurance are his allies. White pieces? He wins nearly half of those games. Black? Still formidable, with a win rate in the low 40s. Also, fair warning: he resigns early just 15% of times, probably because even he knows when the coffee break beckons.

The Opening Enigma

While Ruben's openings are under wraps (literally 'Top Secret'), his extensive use of this mysterious playbook has brought him hundreds of wins and just as many challenges. His record with secret openings reveals a nearly 45% win rate in blitz, proving that keeping opponents guessing is part of his charm.

Memorable Matches & Recent Battles

In his most recent victories, Ruben demonstrated a strong grasp on the Alekhine's Defense—the chess equivalent of a wild ride with a safety belt on. For example, in March 2025, he soundly outmaneuvered his opponent, Parthichess1, winning by resignation after a strategic masterclass. Not all battles end in glory though; May 2025 saw a tough loss against DinamicosKing, a reminder that even grandmasters sometimes must tip their hats.

A Chess Persona

His psychological tilt factor is fairly modest at 17, so when the chips are down, Ruben doesn't fly off the handle. Instead, he finds his sweet spot playing around dawn hours—best avoid him if you want to break his streak before his morning coffee kicks in!

Fun Facts

  • Longest winning streak: 9 games straight — a blitz beast awakening!
  • Longest losing streak: 17, because even legends suffer bad days.
  • Most common opponents include platy3 and vladdobrov, with an 82% win rate against camel_lito — watch out if you’re on his list!
  • His most unpredictable moments come around the 5 AM hour, where brilliance meets caffeine.

In the world of rapid calculations and tactical fireworks, Ruben Felgaer is a name chess enthusiasts respect—and opponents dread. With a combination of secret weapon openings, relentless fighting spirit, and a brain wired for long fights, he continues to make his mark on the global chess scene.

Keep an eye on rfelgaer, because in the blink of an eye, he might just have you checkmated—and wondering how you even got there!

Hi Ruben, here is your personalized post-match review

What you are already doing very well

  • Tactical alertness. Your recent wins feature several in-between moves (Zwischenzug) and mating nets in time trouble (see 60…Qg8+–61…Qg6# in the Sicilian win).
  • Central pawn breaks. In victories you often seize the initiative with …d5 (vs 2.Be2 Sicilian) or d5/d4 as White in the Alekhine game, converting space into activity quickly.
  • Conversion technique when ahead. The endgame squeeze against Parthichess1 shows patient king walks (Kc6-Kb7-Kc6 …) and zugzwang creation.

Recurring problems spotted in the loss streak

  1. Early queen excursions in the Pirc/Czech setups – moves such as 4…Qa5 and 14…Qc5+ left the queen exposed and slowed your development. After 18…O-O you were already down a tempo and a pawn.
    Critical sequence:

    – Black’s pieces are tied up and the d6-bishop is trapped.
  2. Neglecting king safety in opposite-side castling races. Against Alan Pichot you allowed pawn storms (…g5/h5 as Black, or …g4/h4 as White) without securing flight squares, leading to decisive attacks.
  3. Time pressure. In 8 of the last 10 losses you hit <15 s with a tense position still on the board. Good moves stop appearing when the clock is under 10 s.
  4. Pawn-structure concessions on the queenside. Playing …b5/…b4 vs. White’s a4/a5 in the Dragon and Pirc left weak dark-square holes (c6, d5) that strong opponents exploited.

Targeted recommendations

  • Repair the Pirc/Czech branch. Until you have time to patch the move-order details, consider switching to the more solid Classical Pirc with …e5 avoided, or adopt the 1…e5 repertoire you already use successfully against 1.e4.
  • Homework drill: Load the position after 14…Qc5+ (diagram above) into an engine and play against Leela-0.5 sec/move from both sides until you can hold it comfortably.
  • Add a “safety check” to your thinking routine. Before pushing flank pawns in opposite-side castling positions, ask “Can my king breathe if my pawn lands two squares forward?” – this would have flagged 20…g5?! in the 05-05 loss.
  • Clock management micro-goal: Aim to keep ≥45 s by move 25. A simple trick is to hit the clock immediately after making an obvious recapture and think during your opponent’s time.
  • Structural study. Work through 10 model games on the theme “hanging pawns vs. minor-piece activity” – this mirrors many of your Slav and English positions.

Practice plan for the next week

DayFocusTime
MonPirc repair – review 3 games, update repertoire file45 min
TueTactics – 40 puzzle rush attempts, annotate fails30 min
WedThematic blitz vs. friend in Slav/English structures10 games
ThuEndgame drill – rook + pawn vs. rook under 20 s30 min
FriPlay & self-annotate 5 blitz; flag time usage

Keep an eye on these metrics

• Average time left on your clock after move 20.
• Win-rate with Black against 1.e4 before and after the repertoire tweak.
• Accuracy in engine review – strive for <15 % “miss” rate in critical positions.

Final encouragement

You are already competing – and winning – against elite blitz players. A small improvement in opening hygiene and time handling will translate into a significant Elo jump. Good luck, and keep the pieces coordinated!
