Ernesto Javier Fernández Guillén

Ernesto Javier Fernández Guillén, known online as Nesty_Javi_Chess, is a FIDE International Master whose chess profile is built for speed, pressure, and the occasional blunder made at approximately the speed of light.

Playing Style

Bullet is clearly his natural habitat. Across thousands of games, Fernández Guillén has shown a combative style, a strong appetite for long endgames, and an impressive comeback rate. His most common checking piece is the queen, suggesting that even his attacks prefer to arrive with executive authority.

His opening repertoire includes the Caro-Kann Defense, Alekhine Defense, and the sharp Ruy Lopez: Schliemann Defense. In bullet, the Alekhine Defense has been one of his more productive choices, while the Barnes Defense and several gambit lines reveal a willingness to make the position interesting before the clock makes it urgent.

Competitive Record

Fernández Guillén’s recorded online results show remarkable durability. He has accumulated more than 4,000 bullet games, with wins and losses nearly balanced and a substantial number of draws. His longest winning streak reached 22 games, a run long enough to make the “rematch” button feel dangerous.

His statistics also show a preference for fighting chess rather than quick exits. Games average roughly 80 moves, and his early-resignation rate is low. Whether playing White or Black, he tends to keep searching for practical chances until the position, the opponent, or the clock finally objects.
