Christer Hartman – International Master (Username: Charibert)

Christer Hartman, known online as Charibert, is an International Master recognized by FIDE, who has mastered the chessboard with a blend of tactical brilliance and relentless pursuit of victory. With a career spanning over a decade, Christer has achieved impressive feats in blitz chess, boasting a peak rating of 2187 in 2017 and maintaining strong performance close to that level ever since.

Known for an extraordinary longest winning streak of 16 games (yes, 16!), Christer makes opponents tremble — or perhaps just question their life choices — thanks to a remarkable 88.89% comeback rate and a perfect record of winning even after losing a piece. Opponents beware: giving up a pawn here is basically signing up for stomp city.

Blitz is Christer’s playground, where the average rating hovers above 2100 in recent years, and the motto seems to be: Win big, or learn how not to lose. With a win rate close to 60% in over 127 blitz games played with their "Top Secret" opening (we’re all dying to know!), and a spotless streak in daily games, Christer’s chess style is patient, strategic, and built for long endgames — averaging nearly 71 moves per win.

Unlike many, Christer never resigns early: the battle continues until the bitter end 77% of the time. White or black pieces, the success rate stays strong, proving versatility and a knack for turning tables. And while their psychological tilt factor is a modest 4 (meaning losing a game won’t cause an existential crisis), Christer’s rated vs. casual win difference of over 61% signals a serious competitor who shines brightest under pressure.

Against friends and foes alike — including frequent rivals like “spekkio555” (90% win rate!) and “dajac” (a clean 100%!) — Christer’s record is impressively dominant, with many opponents left wondering if their mouse is cursed.

Off the board, Christer remains a humble tactician, perfecting openings, and probably, on occasion, bragging about those rare but satisfying 100% win days.
