Jan Sztwiertnia: The Blitz Virtuoso with a Tactical Twist

Meet Jan Sztwiertnia, a chess player who turns the 64 squares into his personal playground — especially when the clock is ticking. Since 2022, Jan has shown a meteoric rise from modest ratings to nearly hitting 1900 in Blitz and Bullet formats by 2025, proving that patience might be a virtue, but speed kills in his game.

Jan's blitz battles are nothing short of legendary, boasting an impressive win-loss record (2303 wins to 2138 losses) across thousands of games. With an average game length of about 62 moves, it's clear Jan doesn't just blitz out quick moves — he thinks deeply, even under pressure. His comeback rate of nearly 74% means don't count him out when the chips are down, and his astonishing 99% win rate after losing a piece tells us he’s probably the guy who thrives on chaos.

His opening repertoire reads like a seasoned chess encyclopedia, with special affection for the Alapin Sicilian Defense and Giuoco Piano Game, where Jan has double-digit win percentages and even a sparky 80% win rate in some lines. If you find yourself facing his Italian Game or Scotch Game Classical Variation, better bring your A-game — Jan's success there exceeds 60%.

Jan's playing style is a mix of strategic depth and psychological resilience. He resigns early just 1.56% of the time (because giving up too soon is not his style!) and favors endings, with over 60% of his games stretching deep into the endgame. Whether wielding the white or black pieces, his winning percentages stay strong—54.63% and 50.48%, respectively.

When it comes to timing, Jan prefers to unleash his magic during evenings, peaking around 6 to 9 PM with win rates consistently tipping the 55% mark. On weekends, his Saturday performance hits a cool 56%, which makes some suspect that coffee and chess are his true power couple.

Despite all the serious stats, Jan isn’t all tame grandmaster — with a tilt factor of 11 (just enough to keep him fiery but not meltdown-prone), he’s probably cursed or blessed with the same competitive spirit that makes every game a rollercoaster ride. Opponents beware: this is a player who learns from every misstep, laughs off the losses, and comes back swinging.

In the end, Jan Sztwiertnia is a fantastic blend of speed, grit, and finesse, making the chessboard a battlefield and a stage for brilliant comebacks. So if you see him online as SuchASkillIssue, don’t underestimate the skill — but do prepare for an exciting game!
