Alejandro Chinchilla (ACH19)
FIDE Master Alejandro Chinchilla, known by the online handle ACH19, is a chess virtuoso whose passion for the game is as relentless as his opening repertoire is mysterious. With a FIDE Master title under his belt, Alejandro is the kind of player who doesn't just move pieces—he orchestrates symphonies on 64 squares.
Alejandro's blitz rating peaked impressively at 2519 in April 2025, showcasing lightning-fast tactical prowess that leaves opponents scrambling. His bullet best clocks in at a hefty 2296, proving his nerves of steel and uncanny ability to think accurately at breakneck speeds. When it comes to rapid play, he's no slouch either, hitting a peak of 2152. Even in daily chess, where patience is tested, he managed to reach a solid 1720.
With over 8,500 wins in blitz alone and an almost equal number of losses and draws, Alejandro’s dedication to not just playing but battling countless matches is admirable. Often favoring aggressive Sicilian Defense lines like the Open Najdorf English Attack and the Pelikan and Sveshnikov Variations, his games are a cocktail of sharp tactics and deep strategic ideas—sometimes delighting, occasionally baffling, but always entertaining.
His recent games reflect his mastery and fighting spirit. For example, in a thrilling 2025 encounter against "StopBeingTilted", Alejandro dazzled with a beautiful mating net after wielding the Sicilian Defense like a grandmaster should. His ability to come back from setbacks and fight through adversity is remarkable, boasting a comeback rate above 85%—a true chess phoenix.
Off the board, Alejandro is suspected of savoring the challenge of early resignations at a modest 2.38%, because who wants to drag out the agony when victory or defeat is crystal clear? He prefers lengthy battles too, averaging nearly 73 moves per win. Perhaps he enjoys the lengthy psychological chess dance just as much as the checkmates.
As a player, ACH19’s white pieces wield a bit more magic, with a win rate around 52%, while his black pieces hold their own at a respectable 47%. He’s known to tilt occasionally (who isn’t?), but only about 16% of the time—definitely less than some weekend warriors we know.
Alejandro shines brightest around 11 AM, a tactical genius fully awake and ready to unleash complex combinations. Whether grinding out wins on weekend evenings or leading the charge in online blitz mass battles, Alejandro Chinchilla embodies the spirit of chess: resilience, creativity, and just a hint of cheeky flair.
Keep an eye on him, because ACH19’s journey through the chess cosmos is just getting started—and rumor has it, the next legendary checkmate is only a click away.

Positives in Your Recent Games
- Opening Play: You effectively handle popular defenses such as the Pirc Defense and the Sicilian Defense, steering the games into promising middlegame positions early on.
- Active Piece Play: You utilize piece activity well, exemplified by maneuvers like advancing knights aggressively and timely exchanges that clear the way for attacks.
- Capitalizing on Opponent Mistakes: You take advantage of opponent inaccuracies decisively, converting favorable positions without unnecessary risks.
- Execution of Tactical Shots: Your games feature sharp strikes such as sacrifices and precise queen or rook moves to create winning threats, demonstrating strong tactical awareness.
Areas for Improvement
- Early Game Awareness: In some losses, like the game versus RAVI KUMAR, early pawn structure concessions or tactical oversights allowed quick advantages for your opponents. Reviewing these opening phase decisions can help prevent early material or positional deficits.
- King Safety: A few endings showed vulnerability around your king, leading to decisive checkmate threats. Ensuring king safety especially during complex middlegame positions is critical in blitz games where time constraints encourage direct attacks.

- Time Management: Efficiently using your clock throughout the game, especially in critical moments, will reduce rushed mistakes and improve decision-making under blitz conditions.
Opening Performance Insight
Given your frequent use of openings like the Pirc Defense and Sicilian Defense variations, continuing to deepen your knowledge and understanding in these lines will strengthen the foundational phases of your games. Exploring alternative move orders or sidelines could add unpredictability against well-prepared opponents.
Recommendations for Continued Improvement
- Analyze your losses carefully by revisiting critical moments to identify recurring weaknesses or inaccuracies, especially focusing on pawn structure and king safety.
- Practice tactical puzzles regularly to build confidence in spotting and executing sharp tactical ideas quickly.
- Maintain a disciplined approach to opening repertoire development, aiming to reach comfortable middlegame positions where you can capitalize on your strategic and tactical skills.
