Aaron Noah Koellner (The_glorious_Chesscular)
Aaron Noah Koellner is a FIDE Candidate Master who plays online under the unforgettable name The_glorious_Chesscular. What began in April 2020 as a quarantine pastime turned into one of the most entertaining six year climbs in online chess, highlighted by a Blitz peak of 2752 and a Rapid peak of 2395.
A Glorious Origin Story
Aaron entered the online chess world in 2020 with a Blitz rating around 1595 and an immediate appetite for 1.d4. His username promised something special, and the results have now backed up the promise. He earned the Candidate Master (CM) title from FIDE, and his profile lists Rapid as his preferred time control, a format in which his strength adjusted win rate approaches 59.5 percent.
The Six Year Ascent
The numbers tell a steady, sometimes chaotic, upward story. Aaron crossed 2100 Blitz within his first two months, hit 2200 by the end of 2021, and spent the middle years of the decade consolidating in the 2300s and 2400s. Then came the late surge. By 2025 he was touching 2610, and in September 2026 he reached a peak Blitz rating of 2752 (2026-09-23), with a Rapid peak of 2395 (2026-09-04).
Playing Style: A 1.d4 Devotee
Aaron is a system player with a sharp edge. His repertoire is built around the London System and the Colle System, and he has played hundreds of games in the Döry Defense and the East Indian Defense. As Black he turns to the Sicilian Defense, especially the Closed Sicilian and the Alapin Variation, and he has developed a clear fondness for the Australian Defense and the Amazon Attack.
The opening data reveals a player who knows his territory. In Rapid play he has won 92 percent of his games from the Amazon Attack, 92.31 percent from the Modern Defense, and 90.91 percent from the Australian Defense. These are not random openings. They are carefully chosen battlegrounds.
Rivalries and Head to Head Battles
No biography is complete without a good rivalry. Against Aarondielusche, Aaron has been nearly invincible, winning 66 of their 71 games while losing only twice. That is a rivalry in name only.
Against Ruben Gideon Köllner, the script flips. In 22 meetings, Aaron won just 2 games and lost 18. If aarondielusche is the daily confidence boost, the_machine04 is the boss fight that keeps him humble.
Numbers, Comebacks and Chaos
Aaron is one of the hardest players to put away. His comeback rate is 83.63 percent, and he still wins 43.52 percent of games after losing a piece. His one sided loss rate is just 1.5 percent, meaning he rarely gets crushed. Instead, his games tend to go deep, with an endgame frequency of 80.7 percent and average decisive games stretching past 76 moves.
His career includes a 27 game winning streak, a 13 game losing streak, and more than 4,000 wins across Blitz, Bullet and Rapid. He is noticeably stronger with the white pieces, winning 50.14 percent of those games compared with 42.52 percent as Black. His favorite hour to play is exactly midnight, which suggests the glorious chesscular is very much a creature of the night.
