Gianmarco Leiva Rodríguez: The Bullet King of Gianmarco_es
Introduction
Gianmarco Leiva Rodríguez, known online as Gianmarco_es, is a FIDE International Master who treats the one minute clock like a friendly suggestion. His preferred habitat is the bullet arena, where he has produced some of the most eye popping numbers in online chess. He has reached 3016 (2025-12-06) in bullet and 3013 (2026-07-23) in blitz, with a rapid peak of 2561 (2026-07-31) to prove he can slow down when the occasion demands it.
The Online Rise
Gianmarco earned his International Master title from FIDE and then took his game to the digital battlefield. In 2015 he was a promising 1920 rated blitz player. By 2026, his peak blitz rating had climbed to 3013, a meteoric rise built on thousands of games and an almost inhuman amount of stamina at the board.
His bullet rating tells a similar story. A peak of 3016 puts him in the conversation with the very best speed chess specialists on the platform. He has played more than twenty thousand analyzed games, and his volume alone is enough to make a chess server nervous.
Playing Style and Opening Repertoire
As White, Gianmarco is particularly dangerous in the Caro-Kann Defense, where his blitz win rate rises above 64 percent. As Black, he frequently reaches for the Sicilian Defense and its sharpest branch, the Najdorf Variation, relying on deep preparation and tactical alertness to create chaos.
In bullet, he loves to switch between the Scandinavian Defense and modern setups, keeping his opponents off balance from move one. The result is a style that is aggressive, resilient, and very hard to prepare against. His opening success is visible across all time controls, as shown below.
Rivalries and Marathon Battles
No player profile is complete without a great rival. Gianmarco has faced Jose Martinez more than any other opponent, with 337 games between them. The head to head is lopsided: Gianmarco has 70 wins, while jospem has 237. It is the kind of rivalry that keeps a player humble and hungry.
He has also tested himself against tough opposition such as Oleksandr Bortnyk and Sergei Zhigalko, gaining valuable experience in tense, high level battles. These marathon feuds have helped shape him into one of the most durable online competitors around.
