A Chess Omnivore Named Roberto
Roberto Petrulli, known online as robypetrux, is one of the most tireless players on the platform. Since 2020 he has piled up nearly 64,000 rated games, building a profile that is part opening laboratory, part endurance test, and part speed chess therapy. His listed preference may be Rapid, but his results make it clear that bullet is where he truly lets the pieces fly.
A Bullet Heart in a Rapid World
Roberto says Rapid, but his playlists say otherwise. He has played more bullet games in a single month than most players manage in a lifetime. His bullet rating once climbed to 2642 (2025-11-12), a peak that puts him firmly in serious speed demon territory. His rapid peak of 2113 (2023-11-21) and blitz peak of 2443 (2025-08-12) are also impressive, but the real fireworks happen when the clock is nearly irrelevant.
Signature Openings and Beautiful Chaos
Roberto does not play it safe. His most played opening is the wonderfully weird Amazon Attack, a line he has deployed thousands of times in bullet and hundreds of times in blitz. He is also a loyal fan of the Nimzo-Larsen Attack, the Caro-Kann Defense, and the Scandinavian Defense. The result is a repertoire that keeps opponents guessing and gives his games a distinctly unhinged charm.
Familiar Foes
You cannot play this many games without making a few friends, or at least regular sparring partners. His most frequent rival is Nederlaget1, against whom he has played 200 times and won 99. It is a razor thin edge in one of the platform's great grudge series. Against Dr. Norbert Barth the story is different, with Roberto taking 69 wins against 93 losses in their 173 meetings. Add in regular appearances from dragon84, fualls2, and tigrantoomanian, and you have a busy online chess neighborhood.
The Marathon Man
Roberto's style is best described as persistent. His average winning game stretches over 90 moves, and his longest winning streak reached 16 games. When things go wrong, they go wrong properly, with a longest losing streak of 19, but he still finds ways to rescue points.
- He has won 15,103 games on time, a dangerous flagging weapon.
- He has lost on time only 4,106 times.
- His comeback rate sits at 90.88%, meaning he rarely dies quietly.
- Even after losing a piece, he still wins 41.81% of the time.
In short, Roberto Petrulli is the kind of player who makes every opponent earn the full point, takes the weirdest roads to the board, and never runs out of games. That is not just a profile. That is a legacy.
