Teodor-Cosmin Nedelcu (Cocolino31)

FIDE Master & Chess Enthusiast

Teodor-Cosmin Nedelcu, widely known by his chess alias Cocolino31, is a formidable FIDE Master who has made a name for himself across multiple time controls. With an aggressive style and tactical awareness bordering on supernatural, Teodor-Cosmin is as comfortable dispatching opponents in bullet games as he is in rapid and blitz formats.

From 2020 onward, Teodor-Cosmin has dazzled chess communities with a peak bullet rating of an astonishing 2812, proving that when the clock ticks quickly, his brain ticks even faster. His blitz peak rating sits proudly at 2685, showing consistency in rapid-fire matches, and his rapid peak hovered around 2347 back in 2020. A true chameleon of chess time controls, he even maintains a 2000 rating in daily chess – because who says you can’t be both lightning-fast and a patient strategist?

Playing Style & Stats

Known for an impressive 61.18% comeback rate and a penchant for long, thoughtful endgames (averaging about 57 moves per result), he balances cunning calculation with a healthy dose of psychological warfare. His tilt factor is a modest 12, but don’t let that fool you — he finds his best moments early in the day, especially around 10 AM.

Teodor-Cosmin’s opening repertoire boasts a delicious array of defenses and attacks, with strong success in the Slav Defense Exchange, the Queen’s Gambit Declined Modern Variation, and several variations of the Sicilian Defense. In bullet, he shows particular prowess with the Reti Opening Sicilian Invitation and the Slav Defense Exchange, consistently maintaining win rates around or above 50% in high volumes of games.

Anecdotes & Highlights

One of his most recent masterpieces featured a checkmate finish in a tense bullet battle using the Alapin Sicilian Defense. The match lasted a mere 42 moves but was packed with tactical fireworks that would make even Kasparov nod in approval.

Despite being a warrior at the board, Teodor-Cosmin knows how to laugh at chess’s quirks. When asked about his 29.86% early resignation rate, he joked: "Sometimes it's just smarter to say 'checkmate for breakfast' and start fresh." Whether it's a tricky position or a brilliant setup, he reminds us that chess is ultimately about the joy of the game – and sometimes the comedy of errors.

Recent Incredible Feats

  • Crushing a 2654 rated opponent with a swift checkmate in a 43-move bullet clash
  • Maintaining a dominant 2963-2431 win-loss record in blitz
  • Managing a winning streak as long as 21 games — talk about stamina!

Whether you’re a seasoned player seeking inspiration or a casual fan marveling at a chess wizard, Teodor-Cosmin Nedelcu is a name to watch – a mix of tenacity, tactical brilliance, and a love for the game that transcends the sixty-second clock.

Check out his games, and remember: if you dare face Cocolino31, be prepared for fireworks!

Overall Performance Summary

Teodor-Cosmin, your recent bullet game results show a fairly balanced win rate at approximately 50%, meaning you are competitive against your opponents. However, your rating has fluctuated over various time frames — a recent slight decrease over the past 1 and 3 months despite a modest gain over 6 months. Encouragingly, your short-term rating trend slopes suggest positive momentum recently, especially in the last month.

Strengths

  • Solid Opening Knowledge: Your games feature played openings like the King's Indian Defense and Sicilian variations regularly. You seem comfortable with these, creating good attacking chances.
  • Endgame Technique: Your wins include converting complex positions and capitalising on pressure in later stages, indicating good endgame skills.
  • Mid-game Tactics: Accurate piece exchanges and active queen play stand out as helpful in gaining advantageous positions.
  • Time Management: It's apparent you balance speed and precision well, a key skill in bullet chess.

Areas to Improve

  • Closing Games: A few losses came from time pressure or missed tactical opportunities near the end. Focus on simplifying the position when ahead, and staying calm under time stress can help.
  • Opening Flexibility: While your main openings are solid, introducing a wider range or surprise variations may throw opponents off and create chances to win.
  • Defensive Awareness: Pay attention to opponent threats in complex positions, particularly when under time pressure, to avoid unnecessary blunders.
  • Positional Planning: Working on a clearer plan in your opening and middle games, rather than purely tactical moves, could yield better control.

Next Steps for Improvement

  • Review key positions in your losses, especially those where the tide turned due to tactical oversight or time loss.
  • Practice specific endgame drills to solidify converting winning positions under time constraints.
  • Explore alternate openings and variations to diversify your play and make your style less predictable.
  • Use slower time controls occasionally to deepen your understanding of strategic planning.
  • Consider training puzzles focused on defense and counterplay in tricky positions to increase resilience.

Encouragement

Your recent games demonstrate potential and solid foundational skills in bullet chess. The current performance trends are positive, indicating your ability to bounce back and improve. Keep focusing on tuning your game awareness and time management, and your rating and results should reflect your hard work.
