Andres Carrasco Miranda, a.k.a. "Roedor": The Rodent Who Never Stops Chewing

An Opening Gambit

Some players collect trophies. Andres Carrasco Miranda, known to the online chess world as Roedor, collects opponents' will to live. A FIDE Candidate Master and one of the busiest blitz chess grinders on the internet, he has logged nearly 9,700 rated games and shows no signs of slowing down. The username translates to rodent, and it fits perfectly: fast, relentless, and always nibbling at your position until something structural collapses.

The Rise of the Rodent

Every predator has an awkward adolescence. In October 2013, Roedor's bullet rating sat at 1110 and his record was 0-2. By May 2014 he had opened his blitz account with eight straight wins, and the pool was officially on notice. The breakout came in December 2016: 217 games, 141 wins, and a leap from 1887 to 2249 in a single month. From there the climb was slow, stubborn, and very rodent-like, culminating in a blitz peak of 2580 (2026-04-11) and a Candidate Master title from FIDE.

An Opening Book Written After Midnight

With White, Roedor is a d4 loyalist with a taste for chaos. His arsenal features the Catalan Opening, the Slav Defense Bonet Gambit, and the gloriously unhinged Diemer-Duhm gambit, which he has played 131 times for a 58% win rate:

As Black, his calling card is the Sicilian Defense Cobra Variation, 181 games of venomous coin flips. Curiously, the Najdorf is his kryptonite at roughly 36%, proving even monsters have fears. In bullet he keeps a cage full of snakes, including a Center Game played at an 83% clip and a Colle line whose variation is named after a pterosaur, which is honestly on brand.

Style: The Iron Rodent

Roedor does not beat you quickly; he dissolves you. About 77% of his games reach the endgame, where his average win stretches past 67 moves. His comeback rate is a ludicrous 86.84%, and he still wins over half his games even after dropping a piece. His early resignation rate of 1.13% means one thing: he never leaves. Tilt factor? A serene 11. His sharpest form arrives at 8:00 AM with a 72% win rate, while a post-lunch slump at 2:00 PM offers the rest of humanity a fighting chance.

The Deephorvath Files

No biography of Roedor is complete without deephorvath, his most frequent dance partner at 2,369 games, of which Roedor won a staggering 1,876. Whatever deephorvath is doing with their free time, it involves Roedor. Somewhere out there is either the internet's longest running chess feud or its most committed chess friendship. For balance, note that against martinbrxd the record is a chilling 20-0-1, so the joy does get spread around.

Roedor in Numbers

  • Longest winning streak: 31 games, long enough to forget losing exists.
  • Bullet ledger: 1,949 wins against 646 losses, a 75% clip with clicks to spare.
  • Career blitz record: 3,439 wins, 2,892 losses, and 448 diplomatic stalemates.
  • Best day of the week: Thursday, at 64.21%.
  • In nearly 10,000 analyzed games he has technically never delivered the final checkmate. Opponents resign first, out of self respect.

Legacy of a Gnawer

Candidate Master, bullet monster, endgame grinder, and part-time lunch hour liability, Roedor is living proof that titles are earned the hard way: one gnawed pawn at a time, one very tired opponent at a time. Bring cheese at your own risk.
