Marco Dieleman - aka "Dielie"
Marco Dieleman is a formidable chess enthusiast whose passion for the 64 squares shines brightly in the world of fast and furious chess. Whether it’s blitz or bullet, Marco is a force to be reckoned with, boasting peak ratings of 2517 in blitz and an impressive 2516 in bullet. Clearly, speed doesn’t faze this chess player one bit — after all, “Dielie” plays thousands of games a year, each a thrilling battle between strategy, nerves, and occasionally, early resignations (he’s tipped the odds at a 95% early resignation rate, so don’t expect many marathons!).
Style & Stats
Notorious for his lightning-fast decisions and propensity to wrap things up in about 3 moves on average — win or lose — Marco’s style could be described as “blitzkrieg meets express checkout.” His win rates hover around a sturdy 58% in white and 57% in black, making him a tough competitor no matter which color he commands.
With over 45,000 blitz wins under his belt and blazing bullet victories too, Marco’s chess journey is nothing short of epic. He thrives under pressure, and his bullet rating surge up to 2406 shows he's as comfortable as a coffee shop chess hustler as he is in online arenas.
Opponents & Openings
Marco loves mixing things up, employing “Unknown Opening” and his secret weapon “Top Secret” with remarkable success, sweeping up wins with over 55% win rates in mainstays like blitz and bullet alike. His opponents who dare to face him repeatedly include names like jarlcarlander and angelinakali, where he battles fiercely with almost 50% success.
Psychological & Tactical Edge
Despite a modest “tilt factor” of 16 (chess players, you know this is code for “he gets a little grumpy when losing”), Marco shows exceptional resilience when down pieces with a comeback rate of around 4%. Though mostly he likes one-sided games, it’s this occasional comeback spark that keeps fans on the edge of their seats.
A Few Fun Facts
- Average moves per win or loss: about 3.3 — blink and you might miss his games!
- Current winning streak: a humble 0, but his longest was a dazzling 30 wins in a row.
- Rapid and daily chess? Marco’s got them covered too, with perfect rapid win rate (100%) in 6 recorded wins. Daily chess is more laid back, but he’s playing there as well.
- Battle-tested with tens of thousands of fast games, he’s basically a speed chess machine.
Summary
In short, Marco Dieleman is the guy you want on your team in bullet and blitz, but beware: his rapid fire style and quick resignations could have you wondering if the opponent is really even playing chess… or speed chess with ninja reflexes. One thing is for sure, with "Dielie" at the board, the games are fast, furious, and never predictable.

- Use incremental time management in blitz — spend more time in critical positions, less on obvious moves.
Keep up the consistent effort, and you will see further rating improvement and stronger confidence in your games.
