Guillermo José Llanos (ajedrezhoy)
Guillermo José Llanos, known to the online chess world as ajedrezhoy, is a FIDE International Master and a blitz specialist whose rating graph reads like a ski jump played in reverse. His username means "chess today" in Spanish, which is fitting, because Guillermo appears to have decided that yesterday's rating is no longer his problem.
From 1186 to International Master: The Blitz Climb
Every legend has a humble origin. Guillermo's is a single blitz game in January 2019, rated a cozy 1186. He won it, nodded gravely, and vanished for over a year. Then March 2020 arrived, the world stayed home, and ajedrezhoy returned with intent, playing 157 games in April alone and finishing the year above 2200.
From there the climb simply refused to stop. 2022 delivered a 2464 blitz rating, and a relentless 2026 surge carried him past 2500, peaking at 2518 (2026-08-29) along the way, all while stringing together a 13 game winning streak and, more importantly, earning the International Master title from FIDE.
The Opening Repertoire
Guillermo is a man of convictions. With the black pieces, his signature is the Alekhine Defense, played 91 times in blitz with a winning record, because apparently inviting the center forward just to stab it is his idea of hospitality. The Scandinavian Defense and the Czech Defense serve as backup plans that win comfortably more often than not.
With white, he gets experimental, and the experiments keep passing peer review:
- The Hungarian Opening: Wiedenhagen-Beta Gambit, an unbeaten 15 wins and 2 draws in 17 blitz games. Study it quickly before he stops showing it.
- The Amazon Attack: Siberian Attack, converting north of 80 percent of its outings into points.
- A 2026 obsession with opening 1.g3, deployed 18 times and usually followed by bad news for the other side.
His one documented weakness is the English Defense: Blumenfeld-Hiva Gambit, his least successful weapon by a wide margin. Even titled players have one habit that costs them money.
The Rivalry Ledger
Every great career needs a villain, and Guillermo's is Jonathan Goldwasser. They have clashed 25 times in blitz, and Guillermo has lost 14 of them. The irony is delicious: the opponent's username literally celebrates studying openings, and the games go about as well for Guillermo as studying usually goes for the rest of us.
Happily, the ledger flows the other way too. Tom Bombadil has crossed swords 22 times and escaped with exactly one win against twenty defeats, while claudio33 and x-7528128461 combine for a modest 16-0-2, presumably kept around for morale purposes.
Playing Style: The Endgame Landlord
The data paints a clear portrait: Guillermo does not do quick knockouts. An endgame appears in nearly 87 percent of his games, his average win lasts about 78 moves, and his average loss lasts even longer, around 87 moves, because he does not treat losing as a scheduled event. He resigns early in roughly 2 percent of games, meaning opponents must actually finish the job, ideally twice, given that his comeback rate sits at a humiliating 84 percent.
He has won only a handful of games by checkmate. His preferred weapon is the rook check, deployed more than 800 times, repeated patiently until hope exits the opponent's body and the resignation arrives on its own.
One quirk worth knowing: rated Guillermo underperforms casual Guillermo by about 30 points of win rate. The points on the line make him polite. Unrated games are where the fun stops.
When to Play Him
Want a fair fight against an International Master? Consult the schedule first:
- His win rate peaks at 21:00, near 79 percent. Do not queue against him after dinner.
- Wednesday is his kingdom at 82 percent. Tuesday is his bakery at 43 percent.
- At midnight his win rate collapses below 29 percent. The IM title apparently does not survive the clock striking twelve.
The Final Verdict
As of the latest data, Guillermo is in fine form, reeling off long unbeaten runs through 2026 and hovering just above 2500 blitz, with a brief September wobble proving he is human after all. If history is any guide, he will treat that stumble the way he treats his losing openings: absorb it, study it, and come back one patient rook check at a time.
