Pietro Silke Balerna
Better known by his handle PietroCheckmate, Pietro Silke Balerna is a high-volume chess streamer whose Rapid chess journey is one of the most relentless online climbs you will find. He began 2022 as a sub-700 rated player and turned himself into a 2000+ Rapid force by 2026, all while broadcasting the grind to his viewers.
The Long Road to Rapid Glory
Pietro's first recorded Rapid games in early 2022 were modest, but he never stopped playing. Month after month, the rating climbed, dipped, and climbed again. He developed the stamina of a marathon runner and the elastic memory of someone who has seen every possible blunder at least twice.
By August 2026, Balerna reached a Rapid peak of 2216 (2026-08-28). It was the payoff for more than 16,800 rated games across Blitz chess, bullet, Rapid, and daily time controls. His total record includes more than 8,200 wins, a number that would make even the most dedicated club player tired.
Opening Repertoire: The Amazon and the French
Balerna's repertoire is both practical and chaotic. As White, he made a dramatic shift in 2022: early on he was a devoted e4 player, but by 2023 he had rebuilt his opening identity around 1.d4. His database labels his most common pattern as the Amazon Attack, a line he has played thousands of times with almost exactly 50% results.
As Black, he leans on the French Defense, especially the Advance Variation. That choice has served him well in Rapid play, where his win rate in the French Defense Advance sits above 55%. When opponents avoid the French, he often winds up in sharp Sicilian structures, which explains why his results there are less predictable.
Rivalries and Revenge Tours
No online chess journey is complete without a recurring cast of rivals. Pietro's most played opponent is principinodegliscacc, who has faced him 167 times. It is a lopsided friendship: principinodegliscacc has 102 wins, but Pietro has still collected 54 hard-earned victories.
Another tough customer is sloppy-fischer, who has gotten the better of him in 42 of 50 meetings. Not every rivalry is painful. Against big_pisa, Balerna has 29 wins, 1 draw, and no losses, while couldyouletmewinplz might regret the username choice: 19 wins, 1 draw, and zero defeats for Pietro.
A Streamer Who Never Quits
As a streamer, Balerna brings the full emotional range of online chess to his audience. His stats tell the story of a player who refuses to resign early, with an early resignation rate just above 1%. He has delivered a 14-game winning streak, and his profile stats credit him with an 81.49% comeback rate.
The data also suggests he is a creature of the night. His best hour to play is 04:00, where his win rate jumps to 58%. If you see PietroCheckmate online at 4 AM, you are witnessing peak chess performance.
The Grind, The Tilt, and The Tenacity
Balerna's numbers include a longest losing streak of 13 games. That is the sort of stretch that ends most chess careers, but he followed it with a 14-game winning streak. His games average around 68 moves, showing a preference for complex middlegames and long endgames rather than quick knockouts.
Against players rated below him, he wins nearly 70% of the time, but against stronger opponents he still fights for every half point. That combination of volume, resilience, and showmanship makes Pietro Silke Balerna one of the most entertaining grinder streamers on the board.
