Krasimir Marinov (Username: KM-70)

Meet Krasimir Marinov, a chess player who battles it out online with the fervor of a knight on a quest for glory and the patience of a bishop perched on a long diagonal. Known by the moniker KM-70, Krasimir has navigated through the ranks with a blend of tactical sharpness, psychological resilience, and a wee bit of luck that every chess warrior secretly hopes for.

Rating and Performance Highlights

  • Current peak ratings (as recent as 2025):
    Rapid: 1385 (June 2025)
    Blitz: 1218 (April 2024)
    Bullet: 1123 (May 2024)
    Daily: 1266 (October 2022)
  • Total games recorded in online Blitz and Rapid paint a picture of a player who is both battling and thriving in the heat of fast and rapid time controls.
  • Impressive tactical knack with a 79.41% comeback rate – if things look grim, Krasimir probably has a trick (or three) up his sleeve!

Playing Style & Psychology

Krasimir's games tend to be thoughtful yet spirited. He averages about 75 moves per win, proving that giving up early isn't his style—unless it’s to fetch a coffee. The average loss is longer, suggesting he fights hard even when the chips are down. His early resignation rate is a humble 1.04%, so expect him to play until the last piece breathes.

Interestingly, his best time to play is around 9 AM—early riser or just enjoys a good morning coffee with his pawns? The psychological tilt factor stands at 15, which means while he can get frustrated, he mostly keeps his cool. His win rates on white and black hover around the mid-40s to high 40s percentage-wise, reflecting a balanced proficiency with the opening advantage or defending the dark pieces.

Favorite Openings

Krasimir has a fondness for the King's Fianchetto Opening, especially in Blitz and Rapid games, boasting a win rate near 46%. He favors sound defenses like the Scandinavian Defense and the Indian Game Tartakower Attack, sometimes flirting with the Modern Defense when feeling adventurous. The dark squares beware!

Record Against Opponents

KM-70 has an eclectic mix of opponents, taking on players like "dizanata," "thetaclear," and many others in repeated battles. Against some, his win rate proudly stands at 100% (a little reminder that sometimes the opponent Doesn’t Even Know What Hit Them™). Though he has had foes with less friendly outcomes (looking at you, "ropit_12" and some others), Krasimir's resilience shines through.

Noteworthy Games

His latest victory was a masterstroke against ehtz_joemary, where he navigated through the London System with cool precision, winning by resignation after a well-maneuvered attack and solid endgame play – the kind of finish that makes your opponent rethink their whole chess life.

However, even the best have their off days. His most recent loss came after a Scandinavian Defense game against ryanrezzx, reminding us all that chess is sometimes unpredictable and merciless, but hey, it's all part of the grand game.

Fun Facts

  • Longest winning streak: 12 games – clearly on fire at some point!
  • Longest losing streak: 15 games – even superheroes have a bad patch.
  • Must love Mondays: Despite the notorious Monday blues, his win rate hovers around 47%, beating the weekday average sagas.
  • His one-sided losses are less than 2%, so don’t expect many blowouts on his watch.

In the vast galaxy of online chess warriors, Krasimir Marinov stands as a steadfast knight: strategic, persistent, and occasionally quite cheeky on the board. Whether blitzing, rapid-fire dueling, or playing the long daily grind, KM-70 keeps it classy, competitive, and always entertaining.

Hi Krasimir!

Great job keeping an active schedule—your recent games show steady commitment and a fighting spirit. Below is some tailored feedback to help you convert even more of those hard-fought positions into wins.

What you are already doing well

  • Opening identity. As White you handle the King’s Fianchetto set-up confidently, and as Black you embrace the Scandinavian. Knowing your systems allows you to play the first 8–10 moves quickly and stay ahead on the clock.
  • Piece activity. In many wins you seize open files and diagonals early (e.g. 20.Rd1! in your win over ajram58). This willingness to activate rooks and queens is a clear strength.
  • Practical mindset. Several opponents resigned in equal or only slightly worse positions—evidence that you create uncomfortable pressure and keep the initiative.

Key improvement themes

1. Reduce early queen adventures in the Scandinavian

Most losses with Black follow the sequence 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qe5+. The check looks tempting, but it often leads to misplaced pieces and lost tempi (see your game against AbrahamBald). Consider switching to 3…Qa5 or even 2…Nf6, keeping the queen safer and accelerating development.

2. Sharpen tactical vision around loose pawns & pieces

In the loss to RodrigoRFL1984 the critical blunder was 16…Nxd4! (diagram below). You can neutralise many of these shots by adding a quick blunder-check routine: “Are any of my pieces undefended? If my opponent could move twice, what would hurt me most?”


3. End-game technique: Rook & pawn endings

The 86-move marathon versus 19K87 slipped away in a single-rook ending. Investing a few hours on the fundamental rook endings will pay immediate dividends: Lucena Position, Philidor Position and the basic Opposition for king-and-pawn endgames.

4. Time management

Your clock is often above 7:00 when decisive blunders happen. Give yourself permission to spend an extra 20–30 seconds on irreversible moves (captures, pawn pushes, tactical sequences). You will save far more points than you lose.

5. Broadening opening horizons

The King’s Fianchetto is serving you well, but sprinkling in 1.e4 or 1.d4 classical lines will expose you to new pawn structures and tactical motifs—both critical for long-term growth.

Action plan for the next two weeks

  1. Solve 3–5 rated puzzles daily focusing on forks, double-attacks and pins.
  2. Play five games of Scandinavian with 3…Qa5 and annotate them—note where the queen feels safer.
  3. Finish one short course or chapter on basic rook endings; test yourself until you can set up and win the Lucena in under a minute.
  4. During play, verbally ask “What changed?” after every capture or pawn advance. This habit catches hanging pieces early.

Motivation snapshot

Your peak rapid rating so far: 1385 (2025-05-31) — let’s aim to beat it by +50 in the next month!
