Hossein Kamkar (aka PimosB)

Meet Hossein Kamkar, chess enthusiast, rapid strategist, and undefeated Internet warrior in the art of the precariously balanced Rapid games. Known online by his alias PimosB, Hossein's chess journey in 2025 reads like an epic tale of intense battles, narrow escapes, and occasional checkmate masterpieces.

Rating and Performance

Hossein plays primarily Rapid chess, where he has fought through over 1,400 games in the first half of 2025 alone! His peak Rapid rating reached an impressive 616 in April 2025, showcasing a player who steadily climbed the ranks from a humbler 235 at the start of the year. Not just a one-trick pony, he also dabbles in Daily, Blitz, and Bullet formats with noteworthy peak ratings of 663 (Daily), 306 (Blitz), and a fiery 543 in Bullet chess.

His overall Rapid record is a near-even split with 643 wins, 613 losses, and 94 draws—the mark of a tenacious player who fights tooth and nail on every board. He's not afraid to get into the fray, as his average moves per win is a hefty 58.3, reflecting deep and complex battles rather than quick skirmishes.

Playing Style: The Comeback Kid

Hossein’s resilience on the board is legendary: his comeback rate stands tall at 66.7%, proving he's as clever at clawing back from adversity as he is at delivering checkmate. He’s also wary but not shy — with an early resignation rate of just 4%, he's the kind of player who respects a lost cause but won’t throw in the towel too early.

His typical games extend beyond the average, with losses often dragging into the 60+ move range, embodying the classic struggle between experience and opportunity. When playing White, he holds a respectable 49.4% win rate; as Black, he’s not far behind at 45.6%. While he sometimes falls victim to the dreaded tilt (an 11% tilt factor), he knows how to keep his cool and turn tides in his favor.

Favorite Openings & Tactical Flair

Hossein loves to wrestle control of the center, boasting over 100 games in the classic Center Game with a solid 51% win rate. His affection for the French Defense is clear too, often switching between its variations with mixed outcomes but an overall 61% win rate in rapid play — not too shabby!

As a player who enjoys complexity, he’s rarely tempted by quick draws; stalemates and rare draws make up under 7% of his endings, while resignation accounts for most of his wins — a sign he knows just when to capitalize on a winning advantage.

When and How Hossein Wins

Like a true nocturnal strategist, Hossein’s best chess moments happen around 1 AM, when the world is quiet but his mind is buzzing. His highest hourly win rate clocks in around early morning hours (5 to 7 AM) with win percentages nudging into the 54-60% range.

Despite his love for complicated battles, he has a knack for delivering swift finishes. His most recent notable victory was a brilliant checkmate against kingfinhugo, wrapped up in a King’s Gambit Declined opening. This game showcases his sharp tactical awareness and relentless pressure.

Notable Opponents & Rivalries

Hossein’s recent wars on the 64 squares have left a trail of 100% win rates against adversaries like kingfinhugo, noobb23073, and theinbhergz. Of course, every knight falls sometimes; his most recent loss was a tough checkmate delivered by nhoanh12511, reminding us all that even grandmasters face humiliations now and then.

Fun Fact

For a player who often engages in marathon games, Hossein’s longest winning streak stood at a remarkable 9 consecutive wins, while his longest losing streak (the dark side of chess life) peaked at 11 — proving he’s got the heart of a lion and the patience of a chess monk.

In short, Hossein Kamkar aka PimosB is a chess player full of passion, persistence, and a pinch of unpredictability. Whether he's dismantling an opponent or striving to bounce back from defeat, his games are never short of excitement. One can only wonder: what’s next on his road to rapid chess glory?
