Who Is Peter Chaplin?
Peter Chaplin, competing online under the username PeterChaplin, is a blitz-first grinder who has stacked up more than 13,000 games since first logging on in June 2019. His preferred time control is Blitz, where he has played roughly 9,000 games, but he keeps a Bullet habit on the side and a Rapid record that is frankly a little rude. From a low-1900s Blitz debut he has climbed to master-strength online territory, and he did it while refusing, on principle, to play the openings that other people play.
His entire chess philosophy can be summarised in two characters: the letter b and the number 3.
The b3 Doctrine: Opening Repertoire
Peter started life as a respectable d4 player, but in 2020 he defected to the Nimzo-Larsen Attack and never looked back. More than 2,000 of his games begin with 1.b3, including over 1,100 in Blitz, where the Classical Variation alone has produced a healthy 62% score across 593 games. When the b-pawn needs a rest day he rotates to the Amazon Attack (59% in Blitz over 720 games) and even the Rhamphorhynchus Variation of the Colle, an opening apparently named by a palaeontologist with a rating problem.
With Black the philosophy is sturdy defence: the Czech Defense has carried him through more than 800 Blitz games, flanked by the Modern Defense and the Philidor Defense. In Rapid, however, he becomes a genuine problem: an 82% score with the Scandinavian Defense across 140 games, 83% with the oddball Amar Gambit, and a 92% score with the Budapest Defense. He briefly flirted with 1.h3 and 1.Nc3 experiments in 2024 and 2025 before the b3 agenda reclaimed the throne for good.
Style of Play: The Marathon Grinder
Peter does not do quick jobs. Nearly 69% of his games reach an endgame, his average win lasts about 68 moves, and he typically waits until move 7 to take anything, giving the position time to air out. Most telling of all: he resigns early in fewer than 2% of his games, preferring to let opponents personally demonstrate that they know how to mate a king.
- Comeback rate near 80%: even after losing material he still wins over 52% of the time.
- Over 12,000 checks delivered, most of them with the queen, his favourite way of saying hello.
- White scores 58.7% for him, Black 53.6%: the b-pawn travels well.
- Tilt factor: a remarkably calm 15. Bad positions do not rattle him, they just annoy him quietly.
Rivals, Victims, and One Draw Machine
With nearly 100 games against N Towers (60 wins, 16 losses, 21 draws), that matchup is less a rivalry and more a long-term residency. Golf Sookphanich (30-5-1), Melvin (38-7-2) and patzers (30-5-17) have spent years on the wrong side of the grinder. Every hero needs a nemesis, though, and Peter's is mikechesser, who leads their series 24-11 with 17 draws and appears to be the one player who has actually read the b3 scrolls.
Special mention goes to JohanKjeldahl: 33 meetings, 16 draws, a wall built politely out of other walls. And to Golf Sookphanich, whose username promised more than his 10 wins against 19 losses delivered.
Habits, Quirks, and the 5 AM Problem
- Best hour of the day: 6 AM, a 66% win rate. Worst hour: 5 AM, just 34%. The difference is either sleep or coffee, and the data refuses to say which.
- Best day: Sunday at 59%. Worst: Monday at 53%, confirming that chess cannot fix Mondays either.
- He performs roughly 20 percentage points better in casual games than rated ones, meaning his true superpower is playing when nothing is at stake.
- Longest winning streak: 27 games. Longest losing streak: 15, followed by what we can only assume was a long walk.
Career Highlights and Legacy
- A 27-game winning streak, the longest of his career.
- A spring 2026 surge that pushed him past 2300 in both his main formats, with a peak Blitz of 2306 (2026-03-26) and a peak Rapid of 2319 (2026-03-08).
- A Rapid record of 939-215-166, a 71% scoring rate that makes it his most dominant format.
- Over 13,600 analysed games and, remarkably, almost none of his opponents needed to be mated; they usually resigned first, saving him the paperwork.
From a low-1900s newcomer in 2019 to a 2300-plus endgame grinder in 2026, Peter Chaplin stands as living proof that you can build an entire chess career on one humble move. Play 1.b3, take nothing early, refuse to resign, and schedule your games for 6 AM. Simple.
