Eelke De Boer - The International Master of Mayhem
Meet Eelke De Boer, also known in the chess circles (and perhaps in the shadows) as Mackster23. An International Master, bestowed with that shiny FIDE title badge, Eelke is no stranger to the battlefield of 64 squares. Their chess journey is one filled with tactical wizardry, blitz battles, and bullet-speed attacks that leave opponents wondering if they were playing against a grandmaster or a caffeinated squirrel.
Rising Through the Ranks
Starting modestly with bullet ratings around 1900 in 2019, Eelke’s bullet rating skyrocketed to an incredible peak of 2870 in May 2024 – a figure that would make even Magnus Carlsen double-check his queen. More than just a one-trick pony, Eelke’s blitz skills reached an astounding 2882 in April 2025, proving that speed and precision are their trusty sidekicks.
Playing Style and Personality
Eelke’s games tend to be long and grueling affairs, with an average of over 80 moves per win – talk about stamina! They aren’t one to resign early either, showing a glimmer of stubbornness with only 20% early resignations. Their endgame frequency clocks in at nearly 85%, meaning they love testing their technique once the battlefield clears.
Their comeback rate is a staggering 86%, so don’t count them out just because they lost a piece early – Eelke relishes the fightback! And when it comes to psychological fortitude, there’s a 13 on the tilt scale, suggesting that even when the chips fall, this chess gladiator keeps their cool — well, mostly.
Favorite Openings & Secret Weapons
Among their favorite guerrilla tactics are variants of the Scandinavian Defense and Modern Defense, both of which they wield with deadly effect. Eelke even boasts an 83% win rate in the "Modern Defense Standard Line" bullet games — a secret weapon sparingly unleashed!
A Glimpse at Recent Battles
In their most recent notable victory, Eelke showcased brilliant resilience and timing, winning a tense game against chess_mad35 by time, having deftly handled the Scandinavian Defense with flair. But even master tacticians face setbacks: a recent loss came after a hard-fought battle involving the Dutch Defense – a reminder that even IMs aren’t immune to tough breaks.
The Legend Continues
With thousands of bullet and blitz games under their belt, an impressive collection of wins, and a flair for drawing out opponents into long battles, Eelke De Boer is a formidable force on Chess.com and beyond. Whether you face them in rapid or bullet, expect a rollercoaster ride full of clever tricks, stubborn defenses, and moments of brilliance.
