Roberto Navarro Segura: The Blitz Life of Chesster2500
International Master Roberto Navarro Segura answers to Chesster2500 online, where he has built one of the more relentless blitz chess careers around. Since October 2018 he has played more than 18,000 rated games, the overwhelming majority in bullet and blitz, and he still logs on for more. FIDE awarded him the International Master title. The internet awarded him a mountain of blitz games and, presumably, a keyboard with worn-out squares.
The Climb: From 1535 to the Blitz Summit
His blitz rating debuted at 1535 in October 2018 and shot past 2100 within the month, which is chess shorthand for "someone skipped the warm-up." The march never really stopped: a peak blitz rating of 2296 (2026-09-27), a rapid ceiling of 2334 reached back in 2020 when everything was slower, and a bullet peak of 2124. Along the way he strung together a 19-game winning streak, thoughtfully punctuated by an 11-game losing streak to keep things humble.
More than 8,300 bullet wins tell their own story. Roberto does not wait for perfect conditions. He plays, and he lets the rating graph do the weather report.
Opening Repertoire: Theory Optional
Opponents hoping for a quiet afternoon get something else. As Black, his calling card is the Blackburne Shilling Gambit, an ancient trap he has unleashed over 500 times in bullet alone, and which wins a stunning 83 percent of his rapid games. When White takes the bait, the payoff looks like this:
He also spends plenty of time in Queen's Gambit Accepted structures, meets the Najdorf Variation hundreds of times from the White side, and keeps a drawer full of offbeat weapons such as the Amazon Attack, the Amar Gambit and the Barnes Defense. His game database reads less like an opening encyclopedia and more like a prank war.
Playing Style: The Comeback Endgame Grinder
The numbers sketch a fighter. Roughly 76 percent of his games reach an endgame, his average win runs about 67 moves, and when he falls behind in material he still wins more than half of those games, with comebacks above 82 percent. Fewer than one in a hundred of his losses is a one-sided blowout. He is equally capable of resigning early and of sweating through a 70-move rearguard action, which is the chess version of being a complicated person.
His tilt factor sits at a placid 11, his White score is about 57 percent, his Black score about 53 percent, and his most common checking piece is the queen, because subtlety is for slower time controls.
Rivalries: Friends, Foils and One Nemesis
- Cyprien: 86 meetings, 55 wins for Roberto. Favorite sparring partner and favorite source of points.
- Mohamed Awad: 78 games and a losing record for Roberto. Some files remain stubbornly open.
- Akhilesh Pande: the arch-nemesis, 17 wins against 29 losses. Every hero needs one, and Roberto's comes with a losing record attached.
Fun Facts
- Best hour of the day: noon, when his win rate spikes. The lunch-break blitz career is real.
- Best day of the week: Thursday, by a small but smug margin.
- He has played exactly three daily chess games and lost all three. Correspondence chess remains undefeated against him.
The Road Ahead
Thursdays are his best day, his blitz rating has been climbing again, and the Blackburne Shilling Gambit is still out there collecting scalps. The International Master title is on the business card, but the business model is simple: play one more game. Probably blitz. Probably before lunch.
