Playing style & openings

Horacio blends tactical alertness with deep endgame play. They tend to play long, decisive games (avg moves per win ~70) and often reach rich endgames: nearly 80% endgame frequency suggests a player who doesn’t shy from simplifying into technique.

  • Signature habits: early captures around move ~7 and a strong comeback instinct — a high ComebackRate suggests resilience when behind.
  • Favorite openings (especially in Bullet): Sicilian Defense (very successful), Amazon Attack: Siberian Attack, and aggressive tries like the Bird Opening: Batavo Gambit.
  • White repertoire includes the Catalan Opening and solid QGD lines; as Black they often steer games into Sicilian structures and offbeat defenses with fighting chances.

Top opening performances (Bullet highlights): Sicilian Defense (excellent win rate), Amazon Attack: Siberian Attack (strong), and QGD: Chigorin (very effective when employed).

Records, opponents & streaks

  • Most-played opponents include hatatu, yonatan511, and ammomoh.
  • Longest winning streak: 12 games. Longest losing streak: 8 games. Current form fluctuates (recent short losing streaks), but Horacio’s comeback metrics are impressive.
  • Time-of-day edge: unusually strong at late evenings (notably a high win rate around 20:00–23:00 hours) and a statistical peak around 10:00 AM for best performance.
