The One and Only Peroncio
Alejandro Alvarado Diaz, known online as Peroncio, is a FIDE International Master who spends most of his time pretending the Blitz clock is optional. In practice, he treats it like a speed bump. His rating journey began in September 2012 at 1296, and by the end of that same month he was 2074 after 63 chaotic games. That was his warm-up.
His Blitz peak is 2789 (2019-09-24), a number he hit on a September night in 2019 before deciding to play 357 games the following December. His longest winning streak is 21 games, and his longest losing streak is 8 games. He is a player of amnesia: the losses leave, but the Ws keep coming.
A Repertoire Built by a Rebel
Peroncio has a type. He loves a Sicilian Defense: Closed, he is loyal to the King's Indian Attack, and he is not afraid to enter a French Defense battle. His most unexpected weapon is the Hungarian Opening: Wiedenhagen-Beta Gambit, where his Blitz win rate sits above 66%, even though the name sounds like an ancient spell he found in a forgotten notebook.
As Black he shines in the Scandinavian Defense, where he wins almost 71% of his Blitz games. As White he leans on the King's Indian Attack and scores close to 70%. Peroncio is also dangerously patient: his average win lasts 82 moves, which means he will sell no rook for a quick finish. He wants you to watch the whole movie.
Friends, Rivals and the Revolving Door
There is one name that appears far too often in Peroncio's match history: Jose Antonio Herrera Reyes. They have faced each other 60 times, with Peroncio taking 39 wins to 19 losses. That is not a friendship, that is a membership. He has left the rest of the lobby tired, bloodied and twenty moves behind schedule.
Peroncio has had an away match at every hour of the day. His best time is 21:00, when his win rate jumps to about 68%, and his worst time is 0, when the dark and the quiet only seem to confuse him. If you are looking for an edge, queue at 7 in the morning.
The Comeback Doctor
Statistics say Peroncio wins 85.84% of his games after falling into a worse position and still manages a 54.51% win rate after losing a piece. That is less "tactical awareness" and more "grand theft attacker." His one-sided loss rate is only 1.31%, meaning very few people beat him without paying airfare.
He has pushed his way to a strong 2025 form, peaking around 2750 in Blitz again. The board does not always love him, but it never ignores him. Peroncio is an International Master in title, a firework in soul, and definitely worth a viewing, for as long as the clock allows.
