Meet Antonjo Andorfi
Antonijo Andorfi, better known as Tonisub, is a lifelong blitz grinder. While some players chase trophies in slow classical events, Antonijo found his calling on the neon-lit online blitz boards and never looked back. Since his first recorded games in 2017, he has piled up tens of thousands of blitz battles, a mountain of unorthodox opening preparation, and a reputation as the kind of opponent who never makes quitting look easy.
The Long Blitz Journey
One glance at his activity curve tells the story of a player who is simply wired for speed. After building a serious on-year foundation in 2018 and 2019, he took some time in quiet, then roared back in 2025 with a huge burst of games and a peak touch near 2531 (2026-01-27). Along the way he has moved from a promising young grinder into a seasoned competitor who can push through messy streaks and still find a way back to the top of the scoreboard.
His biggest jump arrived in 2025 when he started sweeping through blitz pools at a massive volume. He loves the clock, he loves the fight, and his numbers show a player who is still climbing.
Risky and Lovable Openings
It takes a special player to open games with 1.b3 thousands of times, and Anton is exactly that kind of player. As White, his kingdom centers around the Nimzo-Larsen Attack, a patient and not-so-standard move order. Starting in 2025 he recorded the king sundish fianchetto in more than 3,600 games. Not many players have that kind of devotion to one quiet opening idea, but he does.
With Black, he has built a love affair with the high-level version of the "you cannot attack me if I do not know theory" defense: the Barnes Defense. It is the opening that makes certain chess instructors wince, but Tonisub plays it by the hundreds and somehow turns it into a real, fighting weapon. He also has a long history inside the English Defense: Blumenfeld-Hiva Gambit, another wild child of opening theory.
Watching Anton play can feel like a lesson in good humor: "Just because it's odd does not mean it's bad." There is a method in the madness, and he has the steady rating line to prove it.
Familiar Faces and Rivalries
Every serious online player collects a circle of rivals, and Tonisub has plenty. No one has shown up in his games more than KF3WIN, with 76 meetings and a mostly uncomfortable scoreboard for Tonisub. They have played so often that at this point they probably know each other's breathing pattern.
He also had a fun, near-even duel with Gabriel Massut, a long time with winning vibes on Tonisub's side. When these two met, it was always a good spin: a short, fast fight, then maybe a second one. Want a taste of that rivalry? The final snackbox battle.
Fighter's Heart
The numbers show a player who simply does not go away. He has a 12-game winning streak and a 14-game losing streak, and somehow he seems more amused by the chaos than he should be. Even after losing a piece in his games, his win rate stays near 44%, which is dangerous for anyone trying to sneak a cheap win.
He is actually a fraction stronger with the Black pieces, winning around 46.6% of those games compared to 44.9% with White. His favorite chess hour is 19:00, which suggests that after dinner, he puts the fork down and picks up his clock. He also maintains a fun, unspoiled record in Raptly, though he rarely bothers with time controls that allow thinking. When the need is quick, he is happy.
