Cobro Professor (aka Yohankrokov)
Meet Cobro Professor, the chess force who proves that blitz is a battleground and bullet is a battlefield. Starting from humble beginnings with a blitz rating of under 1000 in 2022, this player has soared spectacularly, peaking at an astonishing 2705 in March 2025. Not bad for someone who probably still forgets where the coffee cup is half the time!
Known for a tactical awareness that makes opponents wonder if they're playing against a grandmaster or a chess wizard with a crystal ball, Cobro Professor has a comeback rate of nearly 80%. When the going gets tough, the tough get going — and probably launch an elegant counter-attack.
Playing styles? Cobro Professor is the master of patience with an average of over 68 moves per win and a whopping 72% frequency of endgames. But watch out mid-game, because if they lose a piece, they still win almost half the time. Resignation rate is low-ish at 9%, hinting that quitting isn’t really in their vocabulary — except maybe when the snacks run out.
Bullet games are another story: with a peak bullet rating of 2579, Cobro Professor can think and execute moves faster than you can say “checkmate.” Their favorite bullet opening? The Van't Kruijs Opening, boasting a jaw-dropping 73% win rate — because why not mess with people’s heads from the very first move?
The player’s rapid rating maxed out at 2364, blending solid technique with fierce competition. Opening repertoire is impressive and varied, with a particular fondness for the Alapin Sicilian and tricky Sicilian Defense variations. Balanced performance as White (50.58% win rate) and Black (46.19%) shows they can dance with both sides without missing a beat.
Cobro Professor’s psychological makeup? A tilt factor of 11 suggests some fiery passion, but nothing a deep breath and a well-timed rook move can’t soothe. Their best time of day to play is… midnight. When most people are asleep, Cobro is busy plotting checkmates and raising ratings — a true night owl warrior.
Recent games tell the tale of a cunning strategist who knows when to press and when to resign gracefully. For instance, a recent gem saw Cobro applying the Queens Pawn Opening with finesse, forcing a resignation from a tough opponent in less than an hour. Meanwhile, their last checkmate was delivered in a lightning-quick Vienna Game — because why not finish with style?
Opponents beware: with a mixed bag of results against familiar rivals but a general trend toward outplaying competition, Cobro Professor keeps their friends close and their checkmated adversaries closer. Win streaks have reached up to 15 games, but even losses are lessons learned the hard way.
All in all, Cobro Professor is a chess player who combines studious preparation, quick hands, and a hint of mischief. Whether it’s blitz, bullet, or rapid, they’re ready to take on the challenge — just don’t ask them why their knight suddenly vanished in the middle of the night.
