Khalid Mujahid (aka SiOtonk) - Chess Player Extraordinaire

Meet Khalid Mujahid, a fearless warrior on the 64 squares with a quirky knack for both brilliant victories and occasionally spectacular defeats. Known in the online realm by his mysterious handle SiOtonk, Khalid approaches chess not just as a game, but as an adventurous saga, where every move could either crown him champion or leave him scratching his head.

Rating Odyssey

Starting with a modest rapid rating of 1200 back in 2018, Khalid showed bursts of vigor and resilience across all formats: bullet, blitz, rapid, and daily. His peak blitz rating flirted with 1378 in late 2024 — not bad for someone who stubbornly plays offbeat openings and sometimes forgets to clock out on time. Bullet chess has been his rollercoaster ride, reaching a thrilling high of 339 before quickly plunging back down — timing seems to be a bit of a mystery with him!

Playing Style & Personality

Khalid’s chess style is equal parts cunning and chaotic. He embraces early resignations about 15% of the time (because hey, who needs prolonged suffering?), but fights tooth-and-nail in endgames, appearing in nearly a third of his matches. He averages around 43 moves per win, showing patience on his best days. His comeback rate impressively stands at 64%, proving he’s a stubborn soul who loves a good underdog story.

Interestingly, Khalid has a tilt factor of 10 — so yes, he knows how to feel the sting of defeat but bounces back (usually after a coffee and some muttering). His psychological edge peaks at 6 PM, when his brain and fingers seem to align perfectly for tactical fireworks.

Opening Choices (or Gambles)

Khalid favors a spicy mix of openings, dabbling in the Sicilian Defense Katalimov Variation where he boasts a 100% win record — at least once! The King’s Fianchetto Opening is another favorite, winning half the time and once managing a draw. Despite some rocky rides on Scandinavian and Sicilian main lines with more losses than wins, Khalid keeps coming back for more, because what’s chess without a little drama?

Famous Battles

Among his memorable victories is a game won by a sneaky time victory against Rumpelblitz in June 2025, showcasing his eye on both the clock and the board with finesse. Another standout win was a sharp checkmate against Solcha89 — pure artistry ending in style.

And when losses happen? They happen spectacularly, often on time and occasionally by unfortunate blunders — like that famous Scandinavian Defense struggle against Brain_a. But every loss is just a setup for the next great comeback.

Opponent Rivalries & Stats

Khalid has tangled the most with faruq-muhammad (16 games) with a tough 18.75% win rate — proving some rivalries are built to challenge. On the brighter side, he proudly maintains 100% win records against a host of opponents, including rumpelblitz, solcha89, jmshmitt, and many others.

Fun Facts & Quirks

• Longest winning streak: 8 games (because Khalid can sometimes go full beast mode).
• Longest losing streak: 10 games (a humbling reminder that even rookies have rough days).
• Favorite time to play: Evening hours around 6 PM; chess magic happens then!
• Most common termination: Winning or losing on time — Khalid’s relationship with the clock is... complicated.

Whether you find him dazzling you with tricky tactics or baffling you with unpredictable moves (and occasional blunders), Khalid Mujahid’s journey through chess is anything but boring. So beware — he might resign early, but he’ll always come back swinging.

Check him out and perhaps challenge him — but don’t blink, or you might miss the next brilliant or bewildering move!
