Florescu Codrut Constantin - International Master
Meet Florescu Codrut Constantin, also known by his online moniker korbul, a formidable International Master whose chess battles have spanned over a decade and a half. With a FIDE title proudly earned, korbul has shown resilience, dedication, and a fair share of cunning on the 64 squares.
Rating and Style
Starting from humble beginnings with a blitz rating just shy of 1400 in 2012, korbul's trajectory is that of a true grandmaster-in-the-making. Peaking recently with a blitz rating soaring above 2700 in early 2024, he’s no stranger to tight battles and brilliant comebacks—as echoed by his astonishing 91.15% comeback rate after setbacks.
A lover of the rapid pace, korbul’s playing style reflects deep strategic understanding combined with a sneaky flair: he boasts an average of nearly 80 moves per win, proving he’s not one for quick tricks, but rather a master of the long game. His tendency to engage in endgames is strong, with an impressive 86.85% endgame frequency, making him a patient grinder who waits for just the right moment to pounce.
The Openings Whisperer
Though known for his “Unknown Opening” repertoire (because why spoil the mystery?), korbul’s secret weapon is a dazzling variety of lines, including the Top Secret opening—probably something even Kasparov would raise an eyebrow at. His love-hate relationship with the Sicilian Defense and Pirc finds him experimenting and occasionally bewildering opponents.
Recent Battles & Noteworthy Games
On May 30th, 2025, korbul showcased his tactical prowess in a thrilling Chess960 blitz duel against PavelChernomordik where, despite looming time pressure, he clinched victory on time with some heroic defensive wizardry. His moves of Bg7, a timely Rf6, and relentless pressure hinted that when the clock ticks down, korbul’s nerves only sharpen.
Of course, not every knight’s tale is without the occasional stumble. On the same day, a hard-fought loss to Fariza2018 reminded us all that even stalwart grandmasters have off days—though knowing korbul, he probably analyzed those mistakes the moment his mouse clicked “Rematch.”
Stats with a Smile
- Total blitz games played: Over 34,000, with a winning smile on 14,000+ of them.
- Known to occasionally say “Resign? Never!” but ends up resigning about 0.6% of the time early—because who’s perfect?
- Loves a good night game, with a psychological peak around 11 PM—ideal for late-night tactical fireworks.
- Has battled opponents from all corners of the internet, from casual chat friends to fierce titled rivals, holding his own with a win rate hovering in the low 40s percent range—a fine balance of humility and hunger.
Outside the Board
When not plotting checkmates or dissecting opponents’ defenses, you might find korbul enjoying a quiet moment, perhaps planning his next secret opening or mulling over why pawns always seem to disappear just as victory is near. With stats to back it and a playful spirit at heart, korbul is a chess warrior who knows that sometimes the real game happens between the ears.
Keep an eye on this International Master—his journey is just getting started, and if his history teaches us anything, it’s that every loss will be a lesson and every win a story told with a grin.
