Justin Dalhouse (MangekyoVision)
From Casual Blitz to Master-Level Grind
Justin Dalhouse, better known online as MangekyoVision, is a tireless online blitz warrior. Since his first rated games in 2019, he has piled up tens of thousands of games, with Blitz as his true home. His username may promise an intense, pinpoint focus, and the results deliver on that promise: he has climbed from the high 1800s to a peak of 2612 in 2026.
The climb was not a straight line. His longest winning streak and longest losing streak are both 15 games, a perfect illustration of a player who never stops pushing and never stops coming back.
Opening Repertoire
Justin is a dedicated 1.e4 player. With white he continually reaches for the Sicilian Defense Alapin Variation, the Advance Variation of the French Defense, and the Caro-Kann Defense. With black he is just as comfortable facing the Closed Sicilian, the Dragon Variation, and the offbeat Australian Defense.
This is a practical but combative repertoire. He would rather fight in messy, tactical waters than stroll through a quiet opening. His results against opponents rated below him are strong, and even when he is clearly outrated, he finds ways to make the game uncomfortable.
Style and Stamina
MangekyoVision plays online chess like an endurance athlete. His average decisive blitz games run around 80 moves, unusually long for fast time controls, and his endgame frequency approaches 84 percent. He also wins an absurd percentage of lost positions, with a comeback rate near 89 percent. Even after hanging a piece, he keeps winning nearly half the time.
His data also reveals a few quirks. His best online hours are around 5 a.m., his tilt factor is honest, and he prefers material chaos to quiet draws. It all adds up to a player who is never boring to watch.
A Rivalry Worth Watching
No account of Justin's career would be complete without mentioning his most-played opponent, Chesstrueno. Their 68-game blitz saga has been a genuine rivalry, with chesstrueno holding the edge. The fact that Justin keeps coming back for more says a lot about his competitive heart.
Whether he is chasing down a lost endgame, grinding another Alapin at dawn, or renewing an old rivalry, Justin Dalhouse remains one of the most persistent and entertaining blitz competitors around.
