Norbert Jakubiak (aka murek91)
In the vast kingdom of online chess, Norbert Jakubiak emerges as a cunning tactician and relentless warrior, better known by his champion's tag murek91. Norbert's chess journey is no ordinary tale—it's a rollercoaster ride through rating peaks, streaks, and strategic quirks that keep spectators guessing and opponents sweating.
Rating Rollercoaster and Style
Norbert has seen his Blitz rating soar to an impressive peak of 2206 in March 2025, while his Bullet rating once touched a blazing 2322 back in November 2020. Not to be outdone, his prowess in Daily and Rapid formats hit high marks of 2155 and 1982 respectively, showcasing his versatility across time controls.
With a penchant for long, intense battles (average moves per win: ~72), Norbert isn't one to give up quickly—his endgame frequency clocks in at a whopping 85%! One might say he loves a good mental marathon more than a sudden bullet blitz frenzy... though that Bullet rating says otherwise!
Opening Repertoire – Shhhh, It’s Top Secret
Norbert’s opening choice? Officially classified as "Top Secret" —and with nearly 3,500 Blitz games under that banner, the mystery deepens. In Bullet, he’s dabbled successfully with variations of the Caro-Kann Defense and Nimzowitsch Larsen Attack, showing a flexible approach and a knack for surprising opponents.
Streaks and Psychology
Having conquered a 27-game winning streak at his peak, Norbert clearly knows how to ride the waves of momentum. But beware: his longest losing streak stretched to 14, proving even the mightiest can have their off days. Luckily, his comeback rate sits at an encouraging 84%, so he fights back harder than a chess ninja on a caffeine rush.
Interestingly, Norbert's best time of day to strike is the early dawn hour of 4 AM—a time when most of us are either asleep or questioning life choices—making him a true daylight blitzer's nightmare!
Recent Battles
One recent victory showcased his masterful checkmate in just 26 moves with the queenside fianchetto opening—the Krause Variation—proving that when murek91 decides to slay, he slays swiftly and stylishly. Opponents beware: his ability to squeeze wins both on the board and on the clock (with plenty of wins on time) means no seconds are wasted!
Fun Facts
- Norbert has logged over 10,900 wins in Bullet chess alone – clearly a speed demon with a mouse.
- His win rate varies dramatically with opponents—from deadly precision against some (100% win rate!) to a humble “practice mode” against others.
- His favorite move? Well, he'd probably say it’s the one that leads to victory... or the one that doesn’t lose immediately.
All in all, Norbert Jakubiak aka murek91 is a chess aficionado whose blend of grit, strategic depth, and a sprinkle of mystery keeps the chessboard—and his fans—on their toes.
Recent bullet performance snapshot
You’ve shown a solid, flexible approach in your bullet games, with a mix of openings that keep opponents guessing. The data indicates a roughly even overall Win/Loss/Draw record, but there is positive movement in the more recent periods. Time pressure has been a challenge in longer sequences, and focusing on a tighter, practical plan can help you convert more close games into wins.
What you’re doing well
- Opening versatility: You’re comfortable using a range of solid setups (Caro-Kann family lines, Nimzo-Larsen, and English/Colle systems), which gives you practical chances against many defenses.
- Adaptability in middlegame: Your games show readiness to switch plans as the position shifts, maintaining pressure and keeping the opponent uncertain about your intentions.
- Endgame potential: In several long games, you demonstrated resilience and the ability to press into endgames where accurate technique can seal results.
Areas to improve
- Time management in bullet: There are games where time pressure limited your choices and hurt your accuracy. Build a simple time budget (e.g., allocate a fixed amount of minutes per phase; avoid long, multi-branch calculations when the clock is ticking).
- Repertoire consolidation: The openings data show strong results in some lines (notably English Opening) but more mixed results in others. Focus on 2–3 openings you know well and study the typical middlegame plans and common tactical motifs you’re likely to face.
- Endgame technique: Improve rook endgames and king activity practice. Bullet games often hinge on precise rook activity and passed pawn handling; add targeted endgame drills to your routine.
- Tactical pattern recognition: Regular practice with puzzles will sharpen your ability to spot forks, pins, and back-rank ideas quickly, which is crucial in fast time controls.
Opening performance and repertoire suggestions
Your openings performance shows room for optimization, with the English Opening performing best among your listed options. Consider emphasizing a compact, easy-to-remember repertoire built around:
- English Opening as a primary weapon for flexible, solid play.
- Caro-Kann Defense with Exchange Variation to maintain a clear, resilient structure and simple plans.
- A secondary Nimzo-Larsen line to keep opponents guessing and to diversify your middle-game paths.
Rating trend and what it means for your study
Your month-to-month and multi-month data show a positive trajectory, with the 3-month trend being the strongest among the recent windows. The longer-term slopes suggest steady growth, though not a straight line. Use this momentum by pairing consistent practice with targeted review of your recent games to reinforce successful patterns and fix recurring mistakes.
Practice plan for the next 2–4 weeks
- Reinforce 2 openings: English Opening (primary) and Caro-Kann Exchange Variation (secondary). For each, study 8–12 model games focusing on typical plans, key exchanges, and common tactical themes.
- Bullet time management drill: play short sessions with a strict timer; after each game, note the move where you spent too long and what you would do differently next time.
- Endgame focus: practice rook endings and king activity in short drills (e.g., 5–10 minute rook endgames) 2–3 times per week.
- Tactics routine: 15 minutes daily of tactical puzzles targeting forks, pins, skewers, and back-rank ideas to improve speed and accuracy under pressure.
