Roberto Calderin - International Master of Chess

Meet Roberto Calderin, or as the online chess world knows him, matanzas1967. Holding the esteemed title of International Master granted by FIDE, Roberto has carved a niche for himself in the electrifying arenas of Rapid, Blitz, and Bullet chess formats.

Known for his ferocious playing style and an almost supernatural comeback rate of 91.65%, Roberto is a player who rarely throws in the towel early - with a minuscule early resignation rate of just 0.78%. When the game goes down to the wire, he thrives, boasting an impressive endgame frequency of 85.09% and a flawless 100% win rate after losing a piece. Talk about turning the tables!

His chess journey has seen thrilling peaks, such as a stunning peak Blitz rating of 2717 in 2021 and an equally fearsome Bullet max rating of 2553 in 2020. Roberto’s Rapidity is nothing to scoff at either, with a Rapid high of 2531. This master’s game is built on deep strategy combined with lightning-fast reflexes.

A strategic mind with patience of a saint, Roberto’s average moves per win hover around 76, while his losses tend to drag longer, suggesting fights full of drama and suspense. He enjoys a slight edge playing White with a 58.45% win rate, but his Black pieces don’t feel neglected either at 53.94%.

Roberto’s fans and foes alike marvel at his longest winning streak of 24 games, which would make even the boldest grandmasters blink twice. Currently, his winning streak stands at a fresh 1 game: it’s safe to say this International Master is always hungry for more victories.

Off the board, Roberto is a tactical wizard with a heart of gold and a quirky sense of humor that can probably checkmate you with a smile. Whether blitzing through thousands of games or taking his time in intense rapid battles, Roberto Calderin is a shining example of dedication, resilience, and passion in the chess universe.
