Playing style & psychology
Guilherme’s style is energetic and tactical. He thrives in positions with imbalances, where quick calculation and nerves can win the day. He often plays long decisive games (average decisive length is high), but when the clock is short he’s at his most dangerous — which explains the community nickname "crazychessbr".
- Comeback rate: impressively high — he finds resources even after tough moments (2158 (2020-11-04)).
- Tilt factor: moderate (13) — he tilts like the rest of us, but bounces back well.
- Best time of day: around 10:00 (local playtimes show higher win rates then).
- Long streaks: longest winning streak 13 games; current winning streak 5.
Openings & repertoire (what to expect)
Guilherme is comfortable in mainline defenses and occasionally loves a wild sideline. He plays both sides well: as White he faces many Sicilian-heavy defenses; as Black he frequently fields the French and Caro-Kann.
- Sicilian Defense — a staple in his Blitz and Rapid play (strong win rate in Rapid).
- French Defense — one of his most-played black systems (including Burn, Exchange and Advance lines).
- Caro-Kann & Scandinavian — reliable choices when he wants solidity.
- Surprise weapons in Bullet: Amazon Attack: Siberian Attack and a handful of forcing sidelines.
