Alvaritosma: The Rising Star of the Caro-Kann

Meet Alvaritosma, a chess player on a journey from humble beginnings (a Daily rating start of 400 in 2024) to a respectable 1409 just a year later. With a knack for the Caro-Kann Defense — scoring an enviable 100% win rate in multiple variations — Alvaritosma’s games are a masterclass in resilience and study of classical openings.

Playing Style & Strengths

Not one to quit easily, Alvaritosma boasts a comeback rate of 75% and an impressive 100% win rate after losing a piece. This player prefers drawn-out battles lasting around 57 moves per victory, favoring steady endgame play (landing an endgame frequency of nearly 63%). When playing with white or black, the win rate stays consistently above 62%, proving versatility on both sides of the board.

Speed Demon

Whether blitz or bullet, Alvaritosma’s rapid firing of moves yields solid results. In 2025, blitz ratings peaked at 1252 and bullet climbed to 1081—the proof that speed does not come at the cost of strategy. With nearly 140 bullet games won (and only 92 lost), Alvaritosma handles pressure like a grandmaster...or at least a boss-level knight!

Opening Repertoire

Alvaritosma dearly loves the Caro-Kann Defense and its many flavors, crushing opponents who dare step onto its turf. Among other pet openings are the Queen's Pawn Opening Mikenas Defense, the Four Knights Scotch Variation, and a smattering of other classical lines. Opponents beware: from 1.e4 c6, it’s often game over, and rarely by resignation.

Memorable Moments & Recent Battles

One of the latest victories arrived with a beautifully executed mating net against FatherChristmas00, demonstrating the keen tactical awareness Alvaritosma brings to every game. However, even legends stumble — a recent loss came against NoIdeaWhatNameKrystian, a reminder that chess is a wild ride full of unexpected twists.

Psychology and Quirks

Alvaritosma maintains a remarkably low tilt factor (only 5%), a zen-like calmness that’s hardly expected given the intensity of bullet time controls. Early resignations are rare, appearing in only about 4% of games — this player fights ‘til kings fall or clocks run out. And speaking of clocks, peak winning hours are between noon and 2 PM, plus a mysterious 100% success rate at 5, 6, and 8 AM... clearly, Alvaritosma is part-player, part chess vampire.

Summary

From rapid improvements and solid performance in classical lines to a sharp tactical eye on the blitz and bullet boards, Alvaritosma is a chess force rising briskly through the ratings. Opponents have been warned: beware the Caro-Kann… and maybe stock up on coffee for those early morning battles!
