Meet Jeremy Roldan
Jeremy Roldan, known online as grinnifwin, is a chess ocean. In over 38,000 rated games he has sailed through openings like the Amazon Attack, survived the Barnes Defense, and built a Blitz empire one quick move at a time. His favorite time control is Blitz, and the stats show it: the volume is enormous, the swings are real, and the love for fast chess is unmistakable.
A Digital Marathoner
Jeremy started around 2009 with modest ratings and a clear passion for the game. Instead of fading away, he turned online chess into a long-distance marathon. By 2026 he had reached a 2436 (2026-07-15) of 2436 (2026-07-15) points, though he would probably say the real trophy is the journey. His Blitz rating trajectory tells the story of someone who never stopped clicking "play again."
He also played plenty of Rapid, Bullet, and a little Daily, but Blitz remains the heartbeat. With more than 32,000 Blitz games, Jeremy has averaged dozens of games per active month for years. That is not just practice. That is a lifestyle.
Loves and Quirks
If you face Jeremy, prepare for the Sicilian Defense and a fondness for sharp, offbeat lines. His most played opening as White is the Amazon Attack, including the Siberian Attack variation. As Black, he regularly meets the Barnes Defense, which may be a gift from his opponents rather than a personal choice. Either way, he turns weird openings into fighting games.
Jeremy wins plenty with White, but his real superpower is the comeback. He recovers from losing a piece about 84% of the time, and his endgame frequency is remarkably high. He also plays best in the morning, around 09:00, according to his own stats. Late-night chess may be fun, but the board seems to smile on him earlier in the day.
On the Battlefield
No biography is complete without the rivals who helped shape it. Jeremy has faced opponent pomonabb35 147 times, a true rivalry that has produced plenty of drama. He also has a nearly even score against Mike M., with 19 wins, 19 losses, and 4 draws. These repeated battles show a player who likes a challenge and never dodges a rematch.
His longest winning streak is 17 games, and his longest losing streak is 16. That kind of bounce-back attitude is common in Blitz, but rare at this scale. He is also prone to tilt, though his overall record suggests he somehow turns tilt into experience.
