Viktor Dmitrenko

International Master (IM) – The Blitz Maestro

Meet Viktor Dmitrenko, also famed in the digital shatranj arenas as Happy1712Drummer. An International Master certified by FIDE, Viktor has earned respect and a fair share of nervous glances from opponents worldwide.

Viktor’s chess journey is a rollercoaster of incredible blitz battles, rapid-fire tactics, and bullet duels so fast they’d make your head spin. His peak blitz rating soared to a stunning 2707 as recently as May 2025 — a rating that places him comfortably in the echelons of speed chess virtuosos.

Known for his resilience, Viktor holds a remarkable 84% comeback rate — this means even when a piece goes missing, you'll find him engineering a fightback worthy of chess folklore. His games are often long marathons, averaging over 72 moves per win, showing that patience and persistence are as much a part of his arsenal as the opening theory.

Playing Style & Psychology

  • Endgame enthusiast: Viktor loves playing deep into the late stages, with an endgame frequency of 83.68%.
  • Early quitter? Never heard of him! Only 0.61% early resignations — he battles until the very end.
  • Best time of day to catch Viktor online: Sharp at 11 AM, the hour of precision and clarity for this chess warrior.
  • Tilt factor: At 12, he’s human — even pros have their off days (but don’t let him see you smile!).

Opening Favorites

Viktor hides a blend of mystery and classical roots in his openings:

  • Top Secret: Over 4500 blitz games played here with nearly a 47% win rate. No one knows exactly what goes on, but it works.
  • Center Game Accepted - Paulsen Berger Variation: His tactical playground boasting a 77% win rate!
  • Caro-Kann Defense variations: A dependable fortress that has won and challenged many.
  • Queen's Gambit Accepted (Showalter Bogoljubov Defense): 60% win rate showing a strategic flair in classical lines.

Recent Heroics & Battles

Some recent victories worthy of applause include a brilliant checkmate against “hongjin” in May 2025, showcasing Viktor’s tactical sharpness and endgame prowess. But lest we forget, even champions suffer defeats. A notable loss to the strong player "pilopa" demonstrates the thrilling highs and lows that make Viktor’s chess journey all the more compelling.

Records & Rivalries

Viktor has squared off most often against opponents like khusenkhojaev (19 games) and dr_min (18 games), crafting memorable clashes that have shaped his style and experience.

Fun Fact

When he’s not delivering crushing blows on the 64 squares, Viktor is probably the only chess IM who can beat your opening repertoire and then casually jam a drum solo in the post-game chat.

One thing’s for sure: with a heart committed to the battle and nerves of steel, Viktor Dmitrenko’s name will continue to buzz through the online chess circuits for a long time to come.

Recent Game Performance

Viktor, your recent blitz games demonstrate strong strategic understanding and tactical execution, especially notable in your ability to capitalize on opponent errors in complex positions. Your wins show effective opening preparation and strong middlegame play in openings like the Caro-Kann and Nimzo-Indian.

  • You have successfully applied pressure in the Scandinavian Defense, maneuvering skillfully in the middlegame to secure winning material.
  • In your Nimzo-Indian games, you showed good positional awareness and timely attacks leading to decisive advantage.
  • Your aggressive approach in the Center Game and Sicilian defenses reflects confidence in dynamic positions.

Areas for Improvement

Despite your successes, there are key areas where you can focus to improve your results further, especially in blitz formats where time pressure is high:

  • Time Management: Some losses were due to time trouble. Practice managing your clock evenly throughout the game to avoid rushed mistakes near the end.
  • Endgame Technique: A few losses involved endgame positions where precise technique could have earned draws or better. Focus on common endgame motifs and conversion techniques.
  • Handling Pressure in Complex Positions: While your attack is strong, work on maintaining composure and calculating accurately in complicated tactical situations to avoid blunders.
  • Defensive Play: Balancing aggression with solid defensive moves will help sustain better positions when opponents counter-attack.

Opening Insights

Your opening repertoire is well diversified with solid performances in:

  • Caro-Kann Defense (Win rate ~46.6%) — ensures a resilient and sound structure.
  • French Defense and London System variations — good balance of solidity and counterplay.
  • English Opening with good positional play and over 54% win rate.

Continue deepening theory and practical understanding in these lines as they fit your style well. Also, review the Nimzo-Larsen and Dőry Defenses, where your win rates are a bit below 45%, for improvements or possible opening adjustments.

Rating Trends and Consistency

Your rating over the past 6-12 months shows a clear upward trend, reflecting improving form and adaptation at higher levels. The most recent one-month dip is minor and the positive slope in your rating changes suggests you are continuing to grow as a player.

  • Keep leveraging your strong points from recent practice to stabilize and reduce the frequency of losses.
  • Analyze your losses carefully to spot recurring themes or mistakes and turn them into growth opportunities.
  • Your overall balanced win rate near 50% against tough opposition shows competitive strength.

Recommended Training Focus

Here are some actionable steps to aid your improvement:

  • Practice blitz games with a focus on steady clock management and avoiding unnecessary risks in the opening phase.
  • Review endgame fundamentals, especially rook and pawn endgames, to improve conversion rates.
  • Train tactical puzzles under time constraints to sharpen calculation speed and accuracy.
  • Deepen preparation in your key openings and explore alternatives in lower win rate lines to add surprise value.
  • Use post-game analysis tools to identify critical moments in losses and learn from them systematically.
