Mariano Mayans Calvo (aka Eivissa)
Candidate Master Extraordinaire
Meet Mariano Mayans Calvo, a Candidate Master wielding the chessboard like a seasoned wizard with a knack for rapid-fire bullet games and commanding blitz battles. If chess was a theatrical performance, Mariano would be the lead actor who occasionally forgets the lines but dazzles with improv brilliance.
Rating & Playing Style
With a peak bullet rating soaring impressively to 2686 in March 2025 and a blitz peak of 2516 shortly before, Mariano thrives in lightning-fast encounters. His rapid rating, while humbler at 2010, shows his ability to adapt and bring crushing checkmates in fewer moves when the clock allows.
Mariano’s style is a cocktail of stubborn endurance and tactical flair: nearly 83% endgame frequency suggests a fondness for long duels where every pawn push counts. Average moves per win (73!) reveal a patience that could rival a Zen master, while his comeback rate above 85% proves he’s not easily rattled — no tilt here, just calm, calculated chess combat.
Opening Arsenal: Secrets and Surprises
He loves a good mystery—“Top Secret” openings dominate his play with nearly 550 games in bullet alone. Beyond this, he favors the Caro-Kann Defense, the Closed Sicilian Defense Grand Prix Attack, and even the trusty Scandinavian Defense. His win rates near 55-58% for these lines make opponents wonder if they’re playing a grandmaster or a grand magician.
Match Highlights
Mariano recently checkmated opponents across multiple time controls, often transforming seemingly quiet positions into victory fireworks. His recent bullet matches show a healthy win/loss ratio with sharp focus and zero draws in November 2024, evolving to over 2500 rating territory with 60+% win rates by mid-2025. When things look tough, Mariano’s comeback rate of 85% means you can count on unexpected twists.
Psychology and Quirks
His best playing hour? The mystical 3 AM slot—because why play chess when you can own the board while others dream? With a tilt factor of just 10, Mariano keeps emotions in check while cunningly attacking. And a confession: occasionally, a resignation might slip in (0.42 early resignation rate), but mostly, he fights tooth and nail until the very end.
Fierce Competitor & Community Player
He’s engaged with a broad spectrum of opponents, from internet legends to everyday knights. Some rivals succumb 100% of the time, while others keep him on his toes. Mariano knows every nuance of his strengths and weaknesses, making him a tough nut to crack and a respected combatant on any digital battlefield.
In Short
Whether it’s bullet, blitz, or rapid, Mariano Mayans Calvo a.k.a. Eivissa is a chess aficionado who blends fierce tactical awareness with endurance, delivering drama-packed games that leave viewers and opponents alike guessing his next brilliant move. Follow him if you dare—but be prepared for a swift checkmate or a sneaky comeback!
Hi Mariano, here is your personalised post-mortem from the last playing session
Quick glance at the numbers
- Current rating trend: climbing back towards your peak.
- Typical playtime: see – notice the dip in the late-night slot.
- Day-to-day swing: (week-ends are clearly your sweet spot).
What you are already doing very well
- Sharp tactical eye – the miniature against jwcheah shows how confidently you punish loose queens: .
- Resourceful under pressure – several wins on time from materially worse positions prove top-tier swindling skills.
- Flexible opening choice – you switch comfortably between 1.e4, 1.d4 and even 1.g3, keeping opponents guessing.
Recurring blind spots
- Over-committing the g-pawn in French/King’s-Indian setups (see loss vs Pham Nam Quan). Advancing …g5/…g4 on move 7–8 left dark-square holes and the king stuck in the centre.
- Time management – four of the six recent losses were flagged with plenty of material on the board. Bullet still demands some structure: open with a pre-rehearsed system, avoid 30-second thinks, and trust your intuition in level positions.
- Inclination to neglect development for pawn grabs – e.g. taking on
b2ora7before castling. In the same game against Playchess_VN, 18…Rb8allowed Qxa7 and the initiative snowballed.
Concrete action plan for the next 2 weeks
- Opening discipline drill • Pick two bullet “skeletons” and stick to them: – White: Vienna Game with 3.f4 or the Nc3-Scandi (your speciality). – Black: pure French (…d5, …Nf6, …c5) without early pawn storms. • Run 20 games each and annotate; abort experimental lines outside this repertoire for a fortnight.
- King-safety checklist (10-second rule) Before pushing a flank pawn ask: 1. Have I castled? 2. Is the centre closed? 3. Can the pawn be targeted by a minor piece? If two answers are “No”, don’t push.
- Clock control routine – Aim to reach move 15 with >30″. – Practise 40 one-minute “hand moves”: random positions where you must play in <2″, to train muscle memory. – Once ahead on time, trade down instead of calculating deep tactics.
- Endgame conversion The loss vs SwimmingTrolley was equal (R+P vs R+P) when you flagged. Do 10 puzzles of “rook and three pawns vs rook” endings; focus on the Philidor & Lucena techniques – they save precious seconds.
- Review key motifs
Add the following to your flash-card set:
• Philidor drawing setup
• Minor-piece fork on c7/e6 after Nc3-Scandi
• Exchange sac on c3 (as Black in Sicilian-like structures)
Motivation corner
Your bullet rating is already elite; ironing out just one of the weaknesses above could easily net +100 Elo. Stay disciplined, keep the mouse warm, and enjoy the grind!– Coach Bot
