Meet AKJett
Anastasios Koukas, better known to the online chess world as AKJett, is a self-made chess warrior. His record spans nearly 24,000 rated games since 2011, a volume that would make even the most dedicated club player wince. While he lists Daily chess as his preferred time control, his rating history tells the story of someone who simply cannot resist the board in any format.
The Long Road From 1200
Anastasios started modestly in mid-2011, hovering around the 1200 mark in Blitz. Year after year the rating climbed: past 1500 in 2013, past 1800 in 2015, and through the 2000 barrier in 2018. His 2564 (2026-02-11) of 2564 in early 2026 shows just how far the journey went. Even in Bullet he touched 2609, proving that his calculation speed can match his patience.
Opening Identities
If there is one thing AKJett loves, it is Petrov's Defense. As Black he has played it more than 2,100 times in Blitz alone, with a healthy win rate above 53%. As White, he leans on the Scotch Game (nearly 60% in Blitz) and the Sicilian Defense: Alapin Variation. In slower Daily games, the Blackburne Shilling Gambit has served him especially well, with a 75% score.
Friendly Fire and Fierce Rivals
No opponent has faced AKJett more often than Anna Cramling, with 150 meetings. Anastasios holds the edge at 95 wins to 44 losses. Not everyone is so lucky: against apostolis1 he trails badly, while against immortallchaos he seems almost unbeatable, winning 35 of 36 encounters.
The Stats That Make You Look Twice
AKJett's numbers are gloriously weird. He once won 29 games in a row, then suffered a 14-game skid. His best hour is 6 AM, where he wins nearly 63% of the time. After losing a piece he still wins 47% of his games, and his comeback rate sits at 87%. Opponents beware: this is a player who does not go quietly.
