A Blitz Knight Rises
Maximiliano Donoso Aguirre, known to the chessverse as MaxiDag30, is a FIDE Candidate Master with a soft spot for fast time controls. He started his online journey in late 2020 with a Rapid rating of 959 and games that belong in a "what not to do" museum. But Maxi did not stay in the museum. He grinded, clicked, and by August 2026 his Blitz rating reached a stunning 2704.
His preferred battlefield is unambiguously Blitz. While others use Blitz to warm up, Maxi uses it as a lifestyle. The numbers tell the story: thousands of Blitz games, a 41-game winning streak, and a FIDE Candidate Master title earned through sheer persistence.
Signature Openings and a Love for the Alapin
Open a MaxiDag30 game and you will likely see him reaching for the Sicilian Defense: Alapin Variation. He has played it 287 times in Blitz and still wins 56.79 percent of those games, making it his comfort food. He also frequently visits the Caro-Kann Defense, the Italian Game: Two Knights Defense, and the wonderfully speculative Blackburne Shilling Gambit.
A typical Maxi Alapin moment looks something like this:
. Calm on the surface, tricky underneath.Rivalries and Revenge Tours
Every knight needs a dragon, and for Maxi that dragon is ice25, his most played opponent with 26 meetings. The series is close, but Maxi holds the edge. Against Giovanni Amaro he has been practically unfair, winning 20 of their 25 encounters while losing only 2. Not every rivalry is so kind. chesslegendarygames has had Maxi's number, leading their head-to-head series 15 wins to 4. Even Candidates Masters have their banes.
Maxi's longest winning streak sits at 41 games. His longest losing streak? 15. We choose not to talk about that one.
The Numbers Behind the Madness
Strip away the gambits and the late-night Blitz sessions, and the stats paint a fascinating picture. Maxi's peak 2704 (2026-08-18) is 2704, but he is far more than a rating. He plays endgames in 77.44 percent of his games, averages nearly 79 moves per win, and even after losing a piece he still wins 53.34 percent of the time. His come back rate of 82.05 percent suggests he never reads the obituary of a lost position until the server says "0-1".
- White win rate: 58.45 percent
- Black win rate: 53.81 percent
- Early resignation rate: just 2.07 percent, proving he does not rage quit easily
- Favorite day to play: Sunday, when he wins 65.64 percent of games
What Makes Maxi Tick
Maxi is apparently a morning person. His best time of day to play is 11:00, where the sample shows a perfect 100 percent win rate. At 3:00 AM he is also dangerous, winning 80.9 percent of games, which likely means he either cannot sleep or simply refuses to. His tilt factor is only 15, meaning it takes a lot to shake his composure. With a style built on staying calm, grinding endgames, and trusting the Sicilian Defense: Alapin Variation even after 287 tries, MaxiDag30 is exactly the kind of player who makes Blitz both beautiful and terrifying.
