  • Title: FIDE Master
  • Preferred time control: Bullet
  • Career games analyzed: 1,213
  • Peak Bullet rating: 2864 (2026-03-12)
  • Bullet rating trend: [[Chart|Rating|Bullet|2024-11-2026-03]]

Playing Style

Agustin mixes speed chess instincts with surprisingly deep endgame persistence. Games are long by Bullet standards and full of checks, tactical swings, and daring comebacks.

  • Endgame frequency: 78.65 percent of games reach endgame themes
  • Average moves per win: about 79
  • Comeback rate: 91 percent — do not count him out
  • Win rate after losing material: 54 percent
  • Early resignation rate: 0.62 — he knows when to stop suffering

Best time to catch him alert: oddly the 04:00 hour has been very productive. For peak Bullet performance try evenings around 20:00 or late nights around 23:00.

Openings and Repertoire

Agustin favors sharp and offbeat systems that lead to messy tactical play. He switches between aggressive gambits and solid Caro-Kann setups depending on the mood and the blunder potential of the opponent.

  • Top Bullet weapons: Amar Gambit (21 games, 61.9 percent win rate), Amazon Attack and the Caro-Kann
  • White highlights: Amar Gambit with an 83 percent win rate in some samples and Four Knights positions that squeeze advantage by surprise
  • Black highlights: Amazon Attack used as a counterpunch with strong results, and a reliable Caro-Kann structure
  • Fun curiosity: in Blitz he has an 80 percent win rate with the Barnes Defense across several games — brave or unusual choices pay off

Study these openings for a sense of his style: Caro-Kann Defense, Scandinavian Defense, Amar Gambit.

Career Highlights and Streaks

  • Longest winning streak: 15 games
  • Current winning streak: 8 games
  • Longest losing streak: 8 games
  • Peak Bullet performance came in March 2026, a period of sustained dominance on the Bullet ladder
  • Notable metric: over 3,600 checks delivered across tracked games. The rook is often the source of lethal checks.

Notable Games

Agustin has a nose for tactical finishes. Here is a short example that shows the speed and brutality of his Bullet tactics.

  • Classic lightning finish (fun illustrative PGN):
  • Memorable opponent match: Brave Scholar

Head-to-Head and Opponents

Agustin has a few familiar rivals. He often meets the same handles on the ladder and typically comes out on top.

  • Most played opponent: GarbageDog10 — record 10 wins, 4 losses
  • Other frequent rivals: volvo333 (8-2-3), brecheisen_gympl (8-2-1)
  • Notable wins against quick tacticians such as golden_kn1ght and likewater

Personality and Fun Facts

Agustin blends seriousness and mischief. He will play an Amar Gambit with a straight face, then follow up with a technical endgame that proves he is not only flash. He is equally comfortable bamboozling opponents in 1 minute games and grinding wins in longer rapid battles.

  • Preferred handle: Mr_Carabali
  • Favorite trick: deliver repeated rook checks until something collapses
  • Quirky stat: two hours with 100 percent win rate at 03:00 and 04:00, but sample sizes are small

Study Tips from Mr_Carabali

If you want to learn from Agustin, practice fast pattern recognition, study endgames, and get comfortable in messy positions. Embrace gambits but learn how to convert advantages when the dust settles.

  • Study tactical motifs that arise from the Caro-Kann and Scandinavian
  • Drill endgame basics — many wins come after long, patient play
  • Play short time controls to sharpen instincts, then analyze deeply afterward
