Dolgan Nyudleev (Chameleon_94): The Bullet Chess Chameleon
Dolgan Nyudleev, known online as Chameleon_94, is a FIDE International Master whose chess identity is built on speed, volume, and adaptability. He holds an official IM title earned over the board, but his online reputation lives and breathes in bullet chess, where his lightning instincts and tireless clicking have made him one of the most recognizable grinders on the platform.
From Unknown to Elite in a Single Month
Nyudleev's online rise reads like a fever dream. In March 2020 his blitz rating hovered around 1180. By April 2020 it had exploded to a monthly high of 2851, a transformation that would take most players years, if they ever achieve it at all. His bullet rating performed a similar magic trick, jumping from 1173 to 2766 in April 2020. He has never looked back.
Since then, Nyudleev has consistently lived in the stratosphere of online speed chess. His bullet peak sits at 2957 (2025-08-28), while his blitz peak reached a breathtaking 3020 (2026-05-15) in May 2026.

Playing Style and Opening Repertoire
As White, Nyudleev is a loyal 1.e4 soldier. His most visited battleground is the Four Knights Game, especially the Spanish Variation, which appears in over 1,500 recorded games. He also loves the Sicilian Defense, particularly the Alapin Variation and its sharp Sherzer Variation, plus the Chekhover Variation when he wants something trickier. Against 1.e4 as Black, he often retreats into the solid Philidor Defense and the Caro-Kann Defense Panov Attack, and he happily plays the Modern Defense and the Amazon Attack when the mood strikes.
His games are not quick tactical sprints. Around 87% of his games reach the endgame, and his average decisive game lasts roughly 80 to 90 moves across both colors. He is a patient predator who strikes first with checks in nearly 60% of his games, and his win rate jumps to 51.63% when he lands the first check. This classic setup, the

The Psychology of a Speed Demon
