Epameinondas Kourousis (aka Diamantidis_13)

International Master – The Tactical Maestro

Meet Epameinondas Kourousis, a chess player whose handle "Diamantidis_13" shines as brightly as his International Master title from FIDE. He's not just another player counting pawns; he's a blitz and bullet wizard with a peak blitz rating roaring at an astonishing 2610 in early 2025!

Specializing in lightning-fast decisions, Epameinondas thrives under pressure, boasting an impressive comeback rate of over 87%. If you dare to take a piece from him, prepare for a fight – his win rate after losing material hovers near 48%, proving he’s a true chess gladiator.

Epameinondas' style can be summed up as resilient and sharp, favoring long endgames that last around 74 moves on winning streaks, but watch out—he’s been known to go on 14-game winning streaks when he's in full flow! His play peaks around 11 AM, perhaps fueling his brain with coffee and cunning strategies.

Opening Arsenal Highlights:
  • Blitz favorite: His secret weapon "Top Secret" opening dominates with nearly 50% win rate over 6755 games – mystery and mastery rolled into one.
  • English Opening (Symmetrical Variation): A perfect 2/2 record with white pieces – symmetry never looked so dangerous.
  • Alekhine’s Defense and Caro-Kann: Both boast 100% success in his handful of appearances – a cherry on top of a versatile arsenal.
Recent Battles in the Arena:

Epameinondas recently clinched a hard-fought victory against LimeInTheCoconut using a sharp Caro-Kann Defense (Advance Tal Variation), winning by resignation – confirming this IM’s knack for grinding down opponents.

Of course, even the best taste a little defeat – his latest loss was a classic Ruy Lopez Morphy Defense Bayreuth Variation encounter against Miamichess, but like any resilient competitor, he bounces right back.

Fun Fact:

With a tilt factor as low as 10 (meaning he rarely lets frustration shake him), Epameinondas is practically the zen monk of the 64 squares. Just don’t get caught in his web – his opponents’ win rates can drop as low as the Arctic!

All in all, Epameinondas Kourousis is a fierce, clever, and consistently improving player who strikes the perfect balance between tactical fireworks and strategic endurance. Watching this International Master at work is like witnessing a grandmasterclass in resilience, skill, and, occasionally, a dash of cheeky brilliance.

Overall Performance and Rating Progress

Your recent rapid games demonstrate a positive development in your chess skills. Over the past month, you have gained an impressive 74 rating points, indicating strong improvement in your play. Your 3- and 6-month gains of 11 points each further support steady progress, with an encouraging upward trend slope of 5.5 to 74 points across different periods.

Your strength adjusted win rate is approximately 49%, which is solid given the varying quality of opponents. This data suggests you are competitively matching your peers and continuing to refine your game.

Insights From Recent Wins

  • Your wins often involve well-prepared openings such as the Nimzo-Indian Defense and Indian Game. This reflects good knowledge of reputable opening systems.
  • Strong strategic play in the middlegame allowed you to capitalize on small positional advantages, leading to eventual opponent resignation.
  • Careful endgame technique was demonstrated, especially in pawn structures and piece activity, as reflected in your ability to convert complex positions successfully.

For example, in the Nimzo-Indian setup, your timely pawn pushes and piece coordination showcased good understanding of typical plans and tensions.

Lessons From Recent Losses

  • Both losses were from well-contested openings such as the Queen's Pawn Opening - Symmetrical Variation and Anti-Nimzo Indian defenses, suggesting a need to deepen your theoretical knowledge in these lines.
  • In some positions, opportunities to simplify or trade pieces favorably were missed, which may have allowed opponents to seize control of the game.
  • Endgame precision can be further improved; practicing key endgame principles and common motifs could reduce lost winning chances.

Focus on consolidating your position after the opening, and be alert to opponent tactical threats earlier to avoid last-minute pressure.

Recommendations for Further Improvement

  • Continue studying your preferred openings to maintain and enhance your preparation, especially less familiar lines where recent losses occurred.
  • Review your recent games carefully, noting critical moments where different decisions could have improved your outcome.
  • Focus on endgame training — concentrate on pawn endgames and minor piece maneuvers for converting advantageous positions.
  • Practice managing your clock effectively during games, ensuring you have sufficient time in complex positions to think deeply.

Next Steps

Keep building on your current momentum — your rating gains show your hard work is paying off. Aim to deepen your understanding of key opening theory and enhance your positional and endgame skills for consistent results.
