Dirk Sebastian: The Pirate King of Online Blitz
Every online chess lobby has a player whose username hints at a secret identity. For Dirk Sebastian, the alias is G_Threepwood, a wink at Guybrush Threepwood, the swashbuckling hero of Monkey Island. Behind the joke stands a serious competitor: a FIDE International Master whose blitz rating has reached 2776 and whose appetite for unusual openings rivals any pirate's hunger for treasure.
From Deck Swab to Admiral
Dirk's rating journey reads like a classic underdog tale. In January 2017 his blitz rating sat at 1943. He grinded, studied, and played with impressive volume, and by August 2026 he hit a career high of 2776 (2026-08-09). The climb was not a straight line; his longest losing streak hit seven games, but his longest winning streak reached eleven, and the comebacks became a habit.
His online ledger includes more than 2,000 blitz games with 1,109 wins against 746 losses. He even peaked above 2700 in bullet, proving the man can move when the clock screams.
A Repertoire Full of Treasure Maps
Dirk does not play like a man memorizing only the main lines. He embraces the weird and wonderful. The Döry Defense is a favorite, and he scores a remarkable 62% with it. The Benko Gambit also features heavily, along with gems such as the Amar Gambit, the Australian Defense, and the delightfully named Amazon Attack: Siberian Attack. He is equally happy playing the Modern Defense or the Czech Defense with black.
- Döry Defense: 62% win rate over 140 games.
- Benko Gambit: 56.6% win rate over 76 games.
- Czech Defense: 59.7% win rate over 119 games.
Do not expect quick kills. His average decisive game runs about 78 moves, and 81% of his games reach the endgame. He is a patient shark who squeezes opponents until they drown.
The Comeback Buccaneer
Perhaps the scariest stat in Dirk's profile is his comeback rate of 89.5%. Even after losing a piece, he still wins 53.25% of the time. His one-sided loss rate is just 1.53%, meaning that when he loses, it is usually a fight to the last drop. He wins 56.39% of his white games and 53.17% of his black games, so he is dangerous from either color. He rarely delivers checkmate, preferring to squeeze out resignations, but in 2026 he started polishing his mate patterns as if adding new cursed swords to his collection.
Foes, Friends, and 2 AM Shenanigans
Every pirate has rivals. Dirk's most frequent online foe is muhammadabdallah32, with 16 meetings and an 11 to 5 record in Dirk's favor. Another regular, ptit_bab, has faced him nine times and lost seven. He also seems to function best when the rest of the world is asleep: his best hour is 2 AM, where he wins nearly 71% of his games, and Saturday is his lucky day. His tilt factor sits at seven, which sounds like a stat from a video game, but his 11 game winning streak suggests he presses the reset button quickly.
