The Blitz Machine
Dmitrij Kollars, who plays under the username GM_dmitrij, is a FIDE Grandmaster that has turned online blitz into a personal sport. His record stretches far beyond the usual weekend rapid circuit: more than 49,000 games on this platform, with blitz as the clear favorite. The chart below is the story of a player who kept finding another gear (or ten):
.He started his online journey in 2016 with a rating that touched 1,865, then spent the 2020s making serious claims above 3,000. His 3225 (2026-07-06) is now deep into everyone-double-takes territory, and the best part is he is still queueing.
Favorite Dreams and Openings
If you, the opponent, only remember one opening from a Dmitrij Kollars game, make it the Caro-Kann Defense. He has played it from both sides in thousands of blitz battles, and it fits his patient style: keep the pawn structure healthy, wait for the mistake, then start out-piece movement the opponent.
He also has a strong relationship with the open Italian games; Italian Game fans will often see him dealing with the Two Knights Defense and turning the middle game into a tactical minefield. His opening win rate chart may not always look polished, but it is efficient:
.Online Rivalries
A player with this many games has to run into the same elite names. Dmitrij has ground out one of the longest online series against Daniel Naroditsky, with their little rivalry crossing into Blitz and Bullet. Nihal Sarin, Vincent Keymer, and Fidel Corrales Jimenez] are also regular guests at his rating card. These repeated meetings have helped shape his fearless, high-volume repertoire.
The Numbers Behind the Grind
Dmitrij has 23,736 blitz wins against 13,755 losses, with about one in eleven games ending in a draw. He also carries a 31-game winning streak and an equally human 17-game losing streak. The stats suggest he never stops trying: a tied fight 91.47% of the time, and even after losing a piece he wins more often than loose.
- Rapid has always been the quieter side, but his peak is over 2,900.
- Bullet barely needs a introduction: over 4,200 wins, with a peak rating of 3,110.
- He enters the endgame in 88% of his games, often outlasting opponents in long rook-and-pawn grindings.
When to Face Him
Data says Dmitrij is at his best around 08:00, likely after the first coffee is still waking up. His tilt factor is 17, which sounds dramatic, but he also has a 91%-plus comeback rate. The opposites: if you face him after his lunch, he might be slightly less interested, but the blitz machine is never really asleep.
