mch: The Blitz Marathoner
If online blitz had a Hall of Fame for sheer volume, mch (mch2236) would have a wing named after them. A d4 specialist, a comeback artist, and a lifelong opponent of sleep, mch has played more than 22,000 analyzed games, almost all of them at blitz speed, and turned a modest 2014 cameo into a 2900 peak.
2901 (2026-08-30) is the headline, but the real story is the grind behind it. mch preferred time control is clearly blitz, and the rating chart below shows why.
From a Three Game Curtain Call to Serious Grinder
mch first appeared in January 2014 with three blitz games, three wins, and a rating that tipped just over 1500. Then came four years of radio silence. When mch returned in September 2018, the warmup was over. The account went from roughly 1600 to the mid 2300s in a single month, then pushed past 2500 before the year ended. Even for an online chess prodigy, that is a steep climb.
The climb continued through 2019 and 2020, with marathon months of 300, 400, and sometimes 500 games. By late 2023 mch had moved into the high 2600s, touched 2800 in December 2023, and saved the best for last with a career high 2901 in August 2026.
Playing Style: Endgames, Comebacks, and 1 a.m. Brilliance
mch is not a player who wants to make a dozen perfect moves and call it a day. Games go long. With an endgame frequency near 85 percent, mch drags opponents into deep, technical fights and regularly outlasts them. The numbers suggest a player with a stubborn streak: a comeback rate above 82 percent means many lost positions are only intermissions.
Time of day matters. mch's best winning percentage arrives at 1:00 in the morning, which explains plenty. When the board is quiet and everyone else is asleep, mch is calmly converting rook endgames. The only downside is a tilt factor of 10, which is a polite way of saying the 1 a.m. calm can occasionally become a 2 a.m. storm.
Openings: A d4 Player With a Taste for Sharp Lines
As White, mch is a devoted 1.d4 player and appears to feel most at home in lines like the Siberian Attack and the Poisoned Pawn Variation. The opening data loves the Amazon Attack family, with thousands of games played at blitz speed. As Black, mch leans on the Philidor Defense and the Czech Defense, mixing solidity with the occasional sharp attempt to take over the center.
The win rate by opening shows that mch is dangerous with either color, though white brings out the best in the account. White win rate is almost 53 percent, while black win rate sits near 46.6 percent. That difference is normal for a player who gets to choose the first move, but mch clearly enjoys it.
Rivalries
No biography is complete without rivals. mch has faced BSWPaulsen in 122 blitz battles, with mch holding a narrow edge of 53 wins against 44 losses and 25 draws. Paul Szuper has been another regular, with 79 meetings and a much more competitive series. Against lower rated competition, mch feasts, winning 58 percent of those games. Against higher rated opponents, the record turns, but mch still scrapes out a win nearly 29 percent of the time.
The result is a profile of a player who keeps coming back, no matter the opponent or the hour. mch may never reveal the mystery behind the 2014 disappearing act, but the 2018 return has been impossible to ignore.
