Throstur Thorhallsson (aka Fosti19) - Grandmaster Extraordinaire
Meet Throstur Thorhallsson, a chess Grandmaster whose blitz moves are so slick they might as well be Icelandic magic. While the world plays chess, this Grandmaster plays chess with style, strategy, and a little Icelandic flair that leaves opponents scratching their heads... or their knight's horns.
With an impressive peak blitz rating soaring above 2550 as recently as March 2024, Fosti19 has danced through over 300 blitz games, winning more than half of them – proving that speed is not just about quick moves, but sharp minds. His rapid play, though less frequent, peaked at a solid 2411, demonstrating versatility across different time controls.
Throstur’s games aren’t just battles; they’re narrative epics lasting on average over 70 moves in wins and sometimes even longer in losses, showing a stamina and love for the endgame that surpasses mere mortals. His longest winning streak is a commendable 8 games, while his “comeback king” stats boast a nearly 94% rate of bouncing back, making him as pesky as a chessboard leprechaun.
Known affectionately in the chess circles as Fosti19, Throstur has mastered the art of unknown openings — a tactic that keeps opponents on their toes since it’s unclear whether he's brewing a masterstroke or a casual Icelandic jig. With a 46% win rate in blitz on these mysterious lines, it’s clear the Grandmaster enjoys a good riddle wrapped in an enigma.
Psychological resilience? Check. Tilt factor? A humble 5 out of 100, meaning he’s way cooler under pressure than your average player who slams their laptop after a bad blunder. When the clock strikes 11 AM, Fosti19 is at his sharpest, ready to perform like the morning chess Viking he truly is.
Always a gentleman on the board but a fierce competitor, Throstur Thorhallsson channels the adventurous spirit of his Nordic roots, striking down opponents with the precision of a glacier carve. Whether you face him online or in person, expect serious chess theatrics sprinkled with wit, resilience, and the occasional sneaky bishop that leaves everyone wondering, “Did that just happen?”
Fun fact: His recent victory over a fierce opponent ended with a cheeky Bxa7+, a finishing flourish worthy of the Icelandic sagas.
Follow Fosti19 to enjoy blitz battles that blend grandmaster skill with Viking tenacity.
