The Bullet File
Tomasz, better known to opponents as thinkerteacher, is the person you find at 3 a.m. queueing up for yet another 1|0 bullet game. His style is less about deep preparation and more about a lightning-fast left hand, a calm head, and the conviction that every blitz of a position can be unblitzed. His bullet rating timeline shows the full arc from 2011 to 2026:
.His first games date back to 2011, when he played nearly all of his 174 bullet games inside a month. That early momentum slowed, but the obsession never faded. He later spent productive seasons in blitz, rapid, and even daily chess, where his record is almost comically extreme. In bullet, however, he grew into a serious force, peaking at 2224 (2026-07-21) in 2026.
Opening Repertoire
If you want to play Tomasz, you need to survive the Scandinavian Defense. He has played the Scandinavian Defense more than 2,400 times as Black, with a win rate somewhere north of 68 percent. He also uses the Caro-Kann Defense as a steady counter, and switches for unpredictable purposes into the Sicilian Defense and various Queen's Gambit setups.
With White he loves to park his pieces in front of the queen's pawn, moving to queen's gambit structures and a heavy London system. His opening spread is strong enough that even when opponents have been prepared, he still finds ways to pull the game into his own tempo. A glance at his success by name confirms the pattern: the more forgotten the line, the happier Tomasz is to play it.
The Rivalry Cabinet
No player appears in Tomasz's logbook more than szachalbomat, who has faced him 450 times. That series is firmly in his control: Tomasz won 338 games to 95 losses, with just 17 draws. It is the kind of score that only becomes better with every rematch.
He also shares a history with issagoat2304. That pairing was competitive at first, but it has shaped his style in its own way: wins (140) and losses (173) in a long, tense series that pushed him to sharpen his endgame and timing. Without that rivalry, Tomasz might not have learned to survive as many speed chess traps. We can link his record against szachalbomat for a closer look.
The Never-Do Cold
What makes Tomasz truly dangerous is not just speed, it's the refusal to fall apart. His tactical awareness numbers show a comeback rate of 86.6 percent and a win rate after losing a piece of 66 percent. He frequently wins games after looking gone.
Ever have that opponent who never resigns early and then somehow takes your flag as the material disappears? That's Tomasz. His early resignation rate is barely 4.9 percent, and he averages about 12 more moves per loss than per win. He will grind a bad position until the clock or the king says no. For opponents it can be exhausting; for fans it is often spectacular.
A Life Known for Small Steps
Tomasz's early years included a strange daily chess phase where his record could jump from a 1800 peak to 580 losses in 31 days, depending on what the queue generated. But those lessons formed his temperament. He plays his best chess after midnight? No, he is strongest at about 9 p.m. if the clock is his friend.
One final note: if you queue into Tomasz in a bullet match, mind the Scandinavian. He is the person who gets up after every blackout and clicks "new game" again, knowing that one win, or one loss, is just one more running summary of a truly long chess life.
