Sergey Koutsin - International Master Extraordinaire

Meet Sergey Koutsin, the International Master with a flair for fast fingers and sharper tactics. With a FIDE title that commands respect and a blitz rating soaring above 2600, Sergey is the kind of player who doesn’t just play chess — he blitzes through opponents like a grandmaster hurricane.

About Sergey

Sergey earned the prestigious title of International Master, proving he’s no amateur fiddler but a dedicated stormer of the sixty-four squares. His games are a rollercoaster of strategy and speed, boasting a peak bullet rating of 2578 and rapid rating close behind, showing versatility across all time controls.

Playing Style and Strengths

Known for an impressive 80.8% comeback rate, Sergey thrives under pressure — losing material is just a minor setback before the triumphant return. His games often stretch the mental endurance muscles, with an average of nearly 79 moves per win, showing a blend of patience and precision.

If you’re playing Sergey late at night — especially around 1 AM, his prime time — don’t be surprised if your queen mysteriously vanishes and a ‘resignation’ quietly follows. His early resignation rate is barely 0.29%, meaning he fights till the horses have fled the battlefield.

Performance Highlights

  • Peak blitz rating: 2633 (April 2025)
  • Peak rapid rating: 2575 (April 2023)
  • Peak bullet rating: 2578 (July 2024)

Sergey has a knack for domination in bullet chess, boasting a win rate over 62% in this lightning mode, and nearly 46% overall against equally matched blitz opponents. His chess arsenal features a mysterious "Top Secret" opening that he has wielded in over 3500 blitz games—probably hiding sorcery behind that code name.

Recent Battles

As of April 2025, Sergey clinched a memorable victory by forcing resignation in a grueling queen’s pawn opening symmetrical variation. His fighting spirit and strategic depth ensure every game is an epic saga worth watching.

Personality Check

With a tilt factor of 11, Sergey is remarkably calm, especially considering the adrenaline rush of blitz and bullet chess. His psychological resilience means he’s not the kind to rage-quit — but the opponent’s annoying loud move? Beware!

Fun Facts

  • Favorite time to play? 1 AM — when the stars align and the pawns tremble.
  • Longest winning streak: 18 games — a chess marathon professional.
  • Current winning streak: 6 games — hot streak activated!

So next time you queue up against Koutsin, remember: you’re not just playing chess, you're stepping into the arena with a tactical wizard who’s part strategist, part speedster, and all heart. Good luck — you're going to need it!

Sergey, here’s some focused feedback based on your latest blitz session.

What’s already working

  • Stable repertoire. 1.d4/ 2.c4 as White and the Nimzo/Queen’s-Indian family as Black give you familiar structures every game – a big practical edge in 3-minute.
  • Dynamic pawn play. Your h-/g-pawn storms (e.g. 25-Apr vs. RafaelVaganian) regularly catch opponents off guard.
  • Practical endgame skills. The Lucby game shows you can squeeze 0-1 endings under time pressure when the clock cooperates.

1. Clock & Conversion – your main growth lever

Five of the seven recent losses were won-or-equal positions lost on the clock.
• Set a move-15 benchmark: aim to keep ≥1 : 50 left.
• When clearly ahead, simplify immediately (trade queens, cancel complications, start pre-moving checks).

Example: vs. Squad1647 you repeated Bc7 ↔ Bb6 instead of fixing the passed a-pawn and bringing the king; the time burn cost the game.

2. Finishing Technique

Even with a material edge you sometimes “hover” instead of executing a straightforward plan.

  • Plan awareness: In rook + pawn endings adopt a two-stage routine – create a passer → activate king.
  • Drill suggestion: 20 Lucena/Philidor positions daily this week.

3. Opening micro-tweaks (keep the repertoire, sharpen the details)

ColourMomentUpgrade
White Lucby game, move 9 …a5 Consider 10.c4 c5 ideas instead of b-pawn advance; you keep the tension and seize space without fixing queenside pawns.
Black Kmoch line with g4 (E20) After 9.g4, test …e5 …Nh7–g5. You punish the over-extended pawn chain faster than in the game where White organised all rooks.

4. Tactical alertness

Missed chance: vs. Squad1647, 14…Qe8 ! would have pinned the c6-knight and solved coordination.

Daily dose: 3 puzzles ≥2700 rating until solved – insist on full calculation, no intuition glances.

Key patterns to revise: deflection, zwischenzug, back-rank tricks.

5. Weekly action plan

  1. Play one 10-game blitz streak aiming to finish each game with >15 s.
  2. Annotate one win + one loss per day – focus on why the position became easier/harder to play.
  3. Endgame trainer: 20 rook-pawn studies daily (see section 2).
  4. Puzzle rush survival until 35 each morning to prime tactics.

Model game to revisit

The endgame squeeze versus Lucby is a perfect template for patient play when material is level but the pawn structure favours you.


Keep the momentum!

Your strategic foundation is solid; tightening clock discipline and conversion technique will push you through the next rating band.
