Facundo Vazquez (aka bettercallcafu)
International Master
Facundo Vazquez, known to many by their online alias bettercallcafu, is an International Master of chess who turns the 64 squares into a playground for tactical fireworks and strategic wizardry. Whether blitzing through a game or bulleting at breakneck speed, Facundo consistently proves that chess is as much about stamina as it is about smarts.
With peak ratings soaring close to GM territory—2798 in Bullet (achieved in early 2025) and a smashing 2842 in Blitz (October 2024)—Facundo’s rapid brainpower has left countless opponents scratching their heads. Their carefully guarded "Top Secret" opening has been deployed over 3,000 times in bullet games, winning a solid 50% of the time, but the player’s secret weapon might just be their uncanny ability to bounce back: an incredible 87% comeback rate after a rough patch.
Facundo’s style can best be described as a marathon runner on caffeine: long games lasting over 80 moves on average, packed with intricate positions and endgame finesse—the endgame frequency is near 85%! Oh, and prone to early resignation on only about 1% of occasions—because why throw away a game when you can find a sneaky tactic instead?
When it comes to timing, Facundo's sharpest moments appear at the crack of dawn—6 AM is their reported best time to play. Lucky for early birds worldwide! But the rating charts reveal some curious quirks; moves at 6 AM deliver a stellar 69% win rate, while 10 AM clocks in at a puzzling zero percent. Maybe that’s when they take coffee break number two.
Notable Stats & Fun Facts:
- Longest Winning Streak: 16 games in a row — probably confuse their opponents with a lucky rabbit’s foot...
- Known for smashing 'Top Secret' openings over 3,000 times — a guarded recipe for victory!
- Regularly battles well-known Twitchers and strong challengers like blitzstream, pablo_dmp, and imcoach with competitive win rates.
- A master of bullet timeouts with an impressive 851 wins via timeout victories. Time pressure is their ally!
In a recent 2025 bullet encounter, Facundo demonstrated their tactical prowess against GMChessrob in a classic Queen’s Gambit Declined Exchange match, winning with style before the game was even finished — talk about leaving them speechless! But even the best humans slip sometimes, like a recent loss on time in a close battle of the Colle System.
Facundo Vazquez is a dynamic, resilient competitor who thrives on the edge of chaos. Whether they're racing the clock or outmaneuvering grandmasters, bettercallcafu proves chess is truly a game for the bold and the brainy alike.
What you’re doing well in blitz
- You keep applying pressure early and often, which helps you seize the initiative and force your opponent to react rather than plan.
- Your opening choices in blitz show a willingness to complicate the position and create dynamic chances. This can overwhelm less prepared opponents and lead to quick wins when the tactics land.
- You show resilience when you’re in rough positions, staying active and fighting for chances until the clock runs out.

Key areas to improve
- Time management under blitz conditions. There are moments when decisions become rushed near the time control. Develop a simple timer plan: allocate a predictable amount of thinking time per phase (opening, middlegame, endgame) and try to maintain several minutes on the clock by move 25.
- Ensure you have a clear plan in the middlegame. In aggressive lines, it’s easy to overextend without a concrete target. Regularly ask: what is my plan for the next 3 moves, and what is the opponent threatening?
- Endgame conversion. In some games you paused or mis-evaluated final positions. Strengthen basic endgame patterns (rook endings, king activity, and pawn endgames) so you can convert advantages reliably even when under time pressure.
- Blunder prevention in sharp lines. Blitz magnifies occasional calculation slips. After identifying a tactical idea, quickly verify the most critical forcing moves and check for better defensive resources from your opponent.
Opening performance and practical advice
You’ve shown good results with aggressive systems such as the Amazon Attack family. This can be a strong weapon in blitz, but it also carries the risk of getting into sharp lines where one inaccurate move can swing the game. Consider pairing your aggressive repertoire with a solid, fast-developing alternative for tougher opponents, so you’re not forced into high-variance lines in every game.
- Keep leveraging openings that lead to active piece play and clear plans, but build a small, reliable backup for when you face precise defenses.
- In training, practice quick decision-making in the first 8-12 moves and identify 2-3 candidate plans you can compare rapidly.

Structured plan for the next 4 weeks
- Week 1 — Time management drills: play 20 blitz games with a plan to have at least 2-3 minutes remaining by move 25. Review any position where you spent more than 30 seconds per move.
- Week 2 — Tactics and pattern recognition: solve 20-30 puzzles daily focused on tactical motifs you’ve encountered (forks, discovered checks, and mating nets).
- Week 3 — Endgame fundamentals: study and practice common rook and king endgames, plus basic pawn endgames. Include 2 short endgame drills after games to reinforce technique.
- Week 4 — Repertoire stabilization: consolidate one primary aggressive line (your Amazon Attack) and one solid, quieter alternative. Play a mix of 60- or 90-second games to test consistency with both.
Longer-term perspective
Your short-term momentum looks positive, but it’s good to balance it with steady long-term improvement. Focus on consistency: keep practicing the same core plans, and steadily build pattern recognition and calculation safety.
