Giovanni Carvalho (kaspavani): The Blitz Marathoner
Giovanni Carvalho, known online as kaspavani, is a blitz chess player who turned online chess into an endurance sport. With nearly 19,000 analyzed games, he has spent more time at a virtual board than most people spend at their actual jobs. His preferred habitat is blitz, but he also roams happily in bullet, wherethe clock is less of a timer and more of a suggestion.
A Slow and Relentless Climb
Carvalho debuted in late 2017 with a blitz rating around 1955, and quickly touched 2000. The real journey, though, was a long grind upward.
shows a player who improved year after year, breaking through to the 2300s in 2023 and eventually reaching a career blitz peak of 2596 (2026-01-28). His bullet rating has soared even higher, peaking at 2666 (2026-09-14), which suggests he can ratchet his calculation speed up when the clock starts screaming.Grit, Openings, and Clock Pressure
What separates kaspavani from the thousands of rising players is durability. His endgame frequency sits near 84%, his early resignation rate is below 1%, and his comeback rate is almost 89%. He plays until the position, or the clock, says otherwise. In fact, he has won more than 3,500 games by timeoutwhile losing fewer than 2,000, making him a genuine flagging menace.
His opening repertoire is built on rock solid foundations. The Caro-Kann Defense is his most trusted weapon,with hundreds of games in both blitz and bullet, while the French Defense and Scandinavian Defense give him reliable ways to steer the game into familiar waters. He also enjoys the Sicilian Defense when opponents are looking for a fight,and his willingness to explore offbeat lines like the Amazon Attack keeps things entertaining.
Rivalries Built One Game at a Time
With that much volume, rivalries were inevitable. No username appears more often in his record than Von Argen,a foe he has faced 81 times with a nearly even score. Against Edgarma_PCAP, he has a slight edge, winning 40 of their 74 encounters. These repeated pairings turn anonymous handles into the closest thing online chess has to old fashioned rivalries.
