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. Not one to shy away from the rapid format either, he boasts ratings well over 2200, holding his own in all time controls.
Style on the Board
With an average of nearly 72 moves per win and a penchant for long endgames (having an endgame frequency of 78%), Matthieu is not a player who rushes his victories. Persistence is key, and with a tactical awareness boasting a remarkable 82.76% comeback rate, he's the kind of opponent who might look lost one moment, only to strike back with a well-placed fork or pin.
Also notable: whenever Matthieu loses a piece, his win rate hits 100%. That’s right, he’s like that comeback kid who’s impossible to put down. Just don’t expect him to surrender early—a meager 1.54% early resignation rate means he fights to the bitter end (or comforting draw).
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
Over thousands of games, Matthieu has amassed an incredible record: over 13,000 wins in bullet chess alone and nearly 9,000 victories in blitz. That's a tiny army of pawns marching relentlessly on the digital battlefield.
Beware if you spot the username 33mangeux or meshter online; these are his most frequent foes, playing hundreds of spells against him. With a 50+% win rate against many opponents, Matthieu knows how to keep his throne.
When Does He Play?
Weekends and evenings are prime time for Matthieu, with peak win chances happening around 9AM to 1PM and 6PM to 9PM. So if you want to catch him napping, avoid those hours!
A Little Quirk to Finish
Matthieu scores higher when playing with White (51.13% wins) compared to Black (45.66%). So if you face him, grab the white pieces or prepare your best gambit — you’re in for a fight!
Whether online blitz or marathon daily games, Matthieu Saint-Guily is a fierce competitor and a beloved rival. Expect a gritty, tactical, and resilient style that keeps every game interesting and every opponent on their toes.
Feedback for Matthieu Saint-Guily — recent bullet games
Hi Matthieu, nice work in these recent bullets. You showed willingness to fight for tactical chances and you’ve proven you can convert complex positions when you stay sharp. There are a few consistent patterns to build on and a few areas to tighten up for stronger results in fast time controls.
What you’re doing well
- You actively seek dynamic solutions and aren’t afraid to complicate a position when the moment calls for it. This is a strong trait in bullet chess and can yield quick wins when your calculations stay precise.
- You create practical threats and keep pressure on the opponent’s king or key pieces, which helps generate good winning chances even from tricky middlegame structures.
- You show resilience in complicated lines and can steer into favorable endgames when the position simplifies, demonstrating good overall fight in your games.
Key improvement areas
- Time management in bullet games: aim to form a short, reliable candidate-move list for critical moments (2–3 forcing options) and commit to a quick plan instead of exploring many branches. This reduces blunders caused by running out of time.
- Guard against tactical oversights and back-rank nets: in several games the attack looked sharp but a lurking back-rank or a missed defensive resource swung the game. Always check for back-rank weaknesses and mating nets before committing to a line.
- Opening consistency: build a compact, practical repertoire. When you know the typical middlegame ideas for your chosen openings, you’ll develop faster and avoid getting stuck in unfamiliar structures in the heat of the clock.
- Endgame technique: practice common rook endings and simple knight/rook endings to improve conversion power when you have a material edge or when the position becomes simplified.
- Tactical pattern recognition: regular puzzles that emphasize forks, pins, skewers, discovered attacks, and queen traps will help you spot decisive tactics more reliably in seconds rather than minutes.
Practical training plan
- Daily: 15–20 minutes of tactical puzzles focused on patterns you encounter in bullet games.
- 3x per week: 25–40 minutes of endgame practice (rook endings, king activity, simplifying with a material edge).
- Weekly: review one recent bullet game and annotate the turning points, plus consider 1–2 alternative moves for key moments.
- Opening focus: choose a simple two-line repertoire for White and Black and study the typical middlegame plans and common responses for 2–3 weeks.
Opening notes and ideas
You’ve explored a variety of setups (for example Nimzo-Larsen-related ideas and other flexible defenses). To gain consistency, pick a small set of reliable lines and learn the core plans behind them so you can develop quickly and stay safe under time pressure. This will help you maintain pressure without getting caught in unfamiliar middlegame ideas.

Next steps
Focus on building a compact repertoire, sharpening quick decision-making under time pressure, and implementing a quick post-game review habit to identify turning points and better alternatives. With small, consistent improvements, you’ll reduce risky moments and improve conversion in your next 15–20 bullet games.
