Thomy Castiglia

Profile: Thomy Castiglia (aka Kalimetrus)

Meet Thomy Castiglia, a rapid chess aficionado who prefers to keep opponents guessing—some say his style is “Top Secret,” though his record suggests it’s more like “Top Mystery.”

Thomy, known online as Kalimetrus, first burst onto the scene with a rapid peak rating of 1107 back in 2017. Despite some rocky rides through the ranks (hello 681 low-point in 2025!), he’s kept his spirits high and his kings safer than most late-night pizza deliveries.

Playing Style & Stats

• Rating Peaks: Rapid 1107, Blitz 948, Bullet 934.
• Overall Rapid Record: 83 wins, 105 losses, 11 draws (because sometimes a tie feels like victory!).
• Favorite Openings: The mysterious “Top Secret” (no spoilers!), the solid Scandinavian Defense with a respectable 53% win rate, and the perfect 100% win rate with Owens Defense and Queens Pawn Opening. Talk about opening with confidence!
• Winning Streak: Once charmed opponents with 5 straight wins — a brief but glorious reign.
• Resilience: Boasts a remarkable 73.8% comeback rate when down. Will fight to the last pawn… or knight.

Quirks & Highlights

Thomy’s best time to strike? Around 8 PM, when his win rate hits a cozy 61.5%. Evidently, caffeine and chess mix well.

Most games are rapid, with an average of about 50 moves to victory, which is a casual stroll by chess standards, but an epic saga for the rest of us. He’s also mastered the fine art of resigning early only about 5% of the time—sometimes bravely going down swinging, sometimes mysteriously vanishing mid-battle.

Recent Battles

Among his freshest victories, Thomy dazzled with a lethal kingside assault and a decisive checkmate last May against ig_ghost01, finishing with a flourish in just 20 moves. That’s the kind of game you’d want to watch on slow-mo.

Of course, losses happen too—like the chilly May day when Ayush4615 ended the war by resignation after 47 intense moves. But Thomy takes it all in stride, adding to a steep learning curve (and a tilt factor kept intentionally low at 8, no rage quitting here!).

In a Nutshell

Thomy Castiglia has proven himself a tenacious and unpredictable player, thriving in the fast-paced chaos of rapid chess and occasionally charming the board with underdog upsets. Whether you’re his opponent or his teammate on the analysis board, one thing’s clear: Thomy plays with heart, humor, and a hint of mystery.
