Mariano Mayans Calvo: The White Isle's Bullet Resident
Most people hear Ibiza and think of beaches, sunsets and DJs. Mariano Mayans Calvo hears it and thinks of premoves. A FIDE Candidate Master, he plays under the username Eivissa, which is simply what the locals call his island, and he has turned that setting into one of the busiest bullet chess careers you will find: more than 8,000 games, over 4,100 wins and a bullet peak of 2756 (2026-07-16). He does not dabble in speed chess. He pays rent there.
Eight Thousand Bullets and Counting
Since late 2024 the graph has been a slow, stubborn climb with the occasional rollercoaster drop, and Mariano treats every dip as a queue-for-another-game situation. His longest winning streak reached 12 games. His longest losing streak reached 10, and he shrugged it off with a tilt factor of just 10, roughly the emotional range of a Mediterranean lizard on a warm rock. The blitz board is no afterthought either, peaking at 2677 (2026-08-29).
The Repertoire: Familiar Beats, Unexpected Drops
As White he opens 1.e4 the overwhelming majority of the time, and his signature is the Sicilian Defense: Closed, with over 850 bullet games and counting. Black duties are shared by the Caro-Kann Defense and the French Defense, but the real party trick is the Amar Gambit, a full 332 games of 1.Nh3, an opening most players only ever meet in memes. For those keeping score at home, his most profitable bullet defense is the Scandinavian Defense at over 57 percent, and yes, he has also been spotted frolicking in the Australian and Barnes Defenses. Island setlists are allowed to get weird. A taste of the Amar in action:
Nemesis Watch
Every hero needs a villain, and Mariano's is CafeconelCapa: 27 games, 6 wins, 20 losses, a deficit he keeps chipping away at with the optimism of a man certain the tide must eventually turn. Elsewhere the waters are friendlier. ugetting has supplied 18 wins against 5 losses, ancientmyth2020 trails 10-18, and Vesna Bogdanovic, his most frequent dance partner, has shared the floor 41 times. The pattern is clear: win or lose, he queues the rematch. It is either admirable or the chess equivalent of ordering one more espresso at 4 AM.
Style: The Marathon Man of One Minute
- Roughly 84 percent of his games reach an endgame, and his average win runs 73 moves, a suspicious amount of actual chess for bullet.
- His comeback rate is nearly 86 percent, and even after dropping a piece he still wins about half the time, like a tourist who loses his sunglasses and keeps dancing anyway.
- He has delivered more than 11,000 checks, the vast majority with the queen, because subtlety is for classical players.
- His golden hour is 3 AM at a 59 percent win rate. By 4 AM it collapses to 43 percent. The espresso crash is real, and it is documented.
- He resigns early in only 29 percent of defeats, preferring to fight until the very last flag falls.
The Undefeated Rapid Champion
And then there is rapid, where the official record reads one game, one win, a perfect 100 percent score that legends are made of. Whether Mariano retired at the top to protect the record or simply finds rapid uncomfortably slow is between him and the clock, but the myth stands: undefeated, untied and entirely unwilling to risk it. A Candidate Master with a grinder's engine, an islander's stamina and a nemesis list he refuses to abandon. Somewhere out there, cafeconelcapa is reading this and refreshing the queue.
