Introduction
Samvel Ter-Sahakyan, known online as Sam_ChessMood, is an Armenian Grandmaster who treats the blitz clock like a sparring partner. With a peak blitz rating of 3135 (2026-07-02), he has played thousands of online games and built a reputation as one of the most relentless speed chess competitors on the platform.
The Online Ascent
Samvel earned the Grandmaster title from FIDE and quickly found his true battleground online. While his daily and rapid ratings show a solid all around player, his blitz graph tells a different story: a steady climb into the stratosphere.
Blitz Battler
Blitz is clearly his home. He has amassed nearly 2,800 wins in blitz, with a longest winning streak of 21 games. His style is aggressive but patient enough to reach endgames in over 86% of his games. He rarely resigns early, and his comeback rate of nearly 89% suggests that no lead is safe against him.
Opening Repertoire
Samvel is a creature of habit in the opening. As Black he leans on the Caro-Kann Defense and the Sicilian Defense: Najdorf Variation, both of which appear hundreds of times in his records. As White he is happy to steer play into queen pawn structures and the London System, though he also enjoys surprising opponents with offbeat tries like the Amazon Attack.
Rivalries
No biography would be complete without mentioning his most frequent online foe: Hikaru Nakamura. Samvel has faced Hikaru Nakamura 77 times in blitz, and while the scoreboard is heavily in Hikaru's favor, Samvel keeps showing up. That persistence is its own kind of grandmaster achievement. He has also traded many games with Daniel Naroditsky and Aleksei Sarana.
