Albert Castillo Dalmau, known on the boards as Albert-Castillo, is a FIDE Master who plays chess like a fire alarm: loud, urgent, and almost impossible to ignore. Under the username that shares his name, Albert has carved out a niche as a bullet specialist, zipping through thousands of games with a grin you can almost hear.
Born in the Blitz
Although his title is contemporary, Albert's heart belongs to bullet. His rating graph reads like a lightning strike: in September 2024 he logged a 579 bullet rating, a peak of 2522, and a last rating of 2502 in the same month, thanks to a wild 491 game sprint. Since then he has settled in as a 2500-to-2700 menace.
The stats behind the sprint say everything: a 47-game winning streak, a comeback rate of nearly 80 percent, and an absolutely absurd tendency to checkmate after getting outplayed all game. He can lose a piece, drop a pawn, and then announce a mate anyway.
Openings with Personality
Albert's repertoire is a treasure chest of chaos. With the white pieces he frequently reaches for the wild Nimzo-Larsen Attack, an opening that can confuse you into thinking you are playing a different game. His most tapped opening is the gloriously named Colle Rhamphorhynchus Variation, a line he has played over 200 times on boards with only minutes on the clock.
With black, he turns to the stalwart Caro-Kann Defense and also a love of the Barnes Defense against nearly everything. He does not mind sharp urbans. His bullet opening performance shows a 56.25 percent win rate with the offbeat Amar Gambit as Black, a statistically absurd preference for the unusual. You can check his full
and either shrug or laugh.An eclectic soul, Albert is just as comfortable in the English Opening: Agincourt Defense as in the Australian Defense. There is no such thing as a boring game to this FIDE Master.
Rivals and Repercussions
Albert's default is the heat of a duel. He has his share of ferocious rivalries on the server, especially against Dragon84, who has faced him 31 times and holds a narrow lead: 18 wins to Albert's 12. The two have encountered every late-night, low-time, all-in battle you can imagine, with many rounds deciding on flags and whisker-thin luck.
Another frequent challenger, cafeconelcapa, has also gone 30 games against him. Albert is human though: against lower rates he feasts at 78.57%, but against higher rated prey he still sometimes snatches wins at 31%. The highest mountain he has reached: 2734 (2026-08-09) rating 2734, achieved in August 2026, which looks like a bullet from a cannon.
Bullet Habit
He prefers to biting on a 1-minute or 1+0 time control, and his internal clock loves 07:00, when the rest of the world is having coffee. Maybe it is the sleepy opponents. His longest losing streak is only 8 games, but his longest winning streak is 47. The fence between them is a park ride.
With over 2,200 bullet games in the books, close to a 49.78% win rate (around 52% adjusted), and a fondness for never resigning when he has material but sake of principle, his recounting in the chess is a user is clear: slap the clock, play Nimzo-Larsen Attack or Caro-Kann Defense, and ride the tide.
