Rasan04: The Sicilian Workhorse of Online Blitz
Some players dabble. Some sample every opening like a buffet. Rasan04 found a recipe in 2019 and has been cooking it ever since: open with e4 as White, invite the Sicilian Defense: Accelerated Dragon to the table as Black, and settle in for a long, grindy, deliciously slow meal. With over 50,000 games logged, an average game length north of 80 moves, and a blitz peak of 2880 (2026-05-29) reached in 2026, this is a story about endurance as much as chess.
The arc is a classic underdog climb: a modest 1516 debut in May 2019, a stubborn march through the 2300s and 2500s, and by 2026 a seat among the strongest blitz players on the platform. Eight consecutive years of showing up, game after game, might be the most impressive stat on this entire page.
The Repertoire: Trust the Grind
As White, the loyalty to e4 is near total; d4 appears roughly as often as a typo. The artillery of choice includes:
- The Caro-Kann Defense: Exchange Variation, played thousands of times: traded structures, traded blows, pure bread and butter.
- The Sicilian Defense: Najdorf Variation, Opocensky Variation, a stunning win rate above 50% across nearly 1,800 games, the true crown jewel of the White repertoire.
- The French Defense: Burn Variation for when the French rears its stubborn head.
As Black, the Accelerated Dragon rules, with the Benko Gambit as backup and a clear willingness to hand over material early. The average first capture lands around move 5.7, which tells you everything: Rasan04 does not believe in long peaceful walks through the middlegame. The flagship setup in all its glory:
Style Notes: Marathoner, Not Sprinter
This is not flashy brilliancy-prize chess. The endgame appears in nearly 88% of games, wins average about 80 moves, and the most common checking piece by a landslide is the rook. This is rook lifting, pawn pushing, squeeze-until-they-crack chess. A 90% comeback rate shows a player who refuses to panic after dropping a piece, and an early resignation rate of just 23% confirms the house motto: the position is never quite dead yet.
The Rivalries
No biography of Rasan04 is complete without BSWPaulsen, the most frequent sparring partner by a wide margin at 347 games, with a record that reads like two magnets stuck together: 130 wins, 161 losses, 56 draws. Close behind are Alan Stein and ErnestoGuevaraLynch, each with over 200 games of shared history. At this point, these are less opponents and more colleagues.
Quirks and Confessions
- Best hour to play: 7:00 AM, with a win rate near 51%. Rasan04 is apparently a morning person, which is rare and suspicious.
- The rapid rating is a museum exhibit: one game, one loss, one rating of 1243, preserved forever.
- Longest winning streak: 13 games. Longest losing streak: 18. Chess giveth, and chess absolutely taketh.
- Holding a Najdorf-Opocensky score above 50% at that volume is basically a superpower.
Legacy
Whether grinding out 90-move rook endings deep into the night or trading haymakers with old rivals for the 300th time, Rasan04 has built one of the most durable blitz careers around: pick a lane (the Dragon's lane, specifically), stay in it, and climb one Sicilian at a time. Respect the grind.
