Sattwik Swain: The Blitz Marathoner
Sattwik Swain, known online as STT170116, is a FIDE Candidate Master who has made online blitz his natural habitat. While he has occasional appearances in rapid and bullet, the numbers say it plainly: blitz is where his chess heart beats fastest.
A Spark in 2023 That Became a 2670 Peak
Sattwik's blitz graph begins with one modest rated game in December 2023, a single win at 1980. Then the real story starts in late 2025: he returned with a burst of 66 games, climbed from 2201 to 2543, and by January 2026 was playing over 240 blitz games in a single month. His peak blitz rating soon touched 2670 (2026-06-13) in June 2026.
Marathon Chess on a Blitz Clock
Even in blitz, Sattwik refuses to rush. His games routinely stretch into long endgames: average decisive games last around 77 to 80 moves, and he reaches an endgame in about 79.5 percent of games. That tenacity translates into a 12-game winning streak and a remarkable 84.38 percent comeback rate. He even wins 49.56 percent of games after losing a piece. If you beat him, you may need to beat him twice.
- Longest winning streak: 12
- One-sided loss rate: only 5.32 percent
- White win rate: 51.75 percent; Black win rate: 50.9 percent
A Repertoire of Flexible Surprises
With White, Sattwik favors flexible and slightly offbeat setups. His most frequent first move in 2026 was 1.Nf3, and he has leaned heavily on the Nimzo-Larsen Attack, the English Opening, and the Colle System. His record with the Nimzo-Larsen Classical Variation and the English's Agincourt Defense sits near 52 percent, showing he can outlast opponents in quiet positions.
As Black, he is a devoted Sicilian Defense player. His favorite branches include the Accelerated Dragon, the Moscow Variation, and the Closed Sicilian, with the Accelerated Dragon producing a tasty 57.38 percent win rate in blitz.
The bodhiknight Problem
Every online player has that one rival. For Sattwik, that rival is Sarbartho Mani. They have met 15 times, and bodhiknight leads heavily: 11 wins, 3 draws, and just 1 win for Sattwik. It is a one-sided scoreline, but those repeated battles have clearly helped shape Sattwik's resilience. When the pairing screen matches him with bodhiknight, you can almost feel a different tournament begin.
When and How He Hits His Best Form
Sattwik is not just a volume grinder; he is also a creature of habit. His best day for winning is Sunday at 57.42 percent, and his strongest hour is 08:00, where he wins nearly 63 percent of games. His tilt factor is a manageable 12, and he rarely resigns early. Against lower-rated opposition he converts 65.19 percent of games, while against higher-rated players he still manages to steal 24.1 percent.
If you meet STT170116 across the board, bring patience, a good endgame, and maybe avoid playing him on Sunday morning.
