Meet Matthieu Saint-Guily, AKA NicyFlash777
Matthieu Saint-Guily is a chess player whose rating journey could be described as a rollercoaster ride… with a rocket booster installed.
Starting from blitz ratings around 1000 back in 2019, Matthieu didn't just improve; he skyrocketed to an impressive 2504 by 2025, proving that persistent clicking and brain scratching pay off. His bullet rating is no less fierce, hitting a peak at 2636 in 2024 before settling just below that in 2025.

Style on the Board

Opening Repertoire That Packs a Punch
Matthieu loves his Sicilian Defense — particularly the Four Knights Variation — boasting a solid 53%+ win rate in blitz. He's also a fan of the Scotch Game, which yields his best blitz win percentage of 56.6%, making him a double-edged sword in the opening phase.
His Opponents’ Worst Nightmare
