Marianna Chierici - Woman FIDE Master & Tactical Dynamo

Meet Marianna Chierici, a chess enthusiast who’s not just playing the game but setting stages ablaze with the proud title of Woman FIDE Master. With a peak blitz rating soaring to 1951 and a bullet max rating at 1910—Marianna isn't just moving pieces; she's making moves that leave opponents gasping for air and the audience screaming for more.

Starting with a modest daily rating of 1346 way back in 2012, Marianna's rapid rise is like a well-calculated gambit: bold and uncompromising. Her bullet games are a whirlwind—60 games with a phenomenal 71.67% win rate, and in blitz battles, she’s even more lethal, stacking an incredible 85.71% win rate. Opponents beware: when Marianna sits at the board, the “Top Secret” opening system is her trusty weapon, boasting victory after victory.

When it comes to streaks, Marianna once went on a streak of 14 straight wins. Fourteen games! That’s enough to convince anyone she’s got a secret potion for success, or maybe just a plucky pawn with a vendetta. Even her losses refuse to be drawn out affairs—her longest losing streak stands humbly at two, showing she bounces back quicker than a knight forks two kings.

She thrives in the endgame, with nearly 79% frequency, and averages close to 75 moves per win—talk about a patient strategist! Whether wielding the white or black pieces, Marianna flexes her tactical muscles with white, enjoying an outstanding 86.84% win rate, while still showing fierce resolve with black at 62.16% wins. In games where she loses material, Marianna’s comeback rate is a jaw-dropping 78.57%, proving she’d rather wrestle the board back to victory than concede defeat.

Marianna's psychological stamina is as impressive as her chess skills. She’s got a tilt factor of just 2, meaning only minor hiccups rattle her concentration, and her best playtime is midnight—or as she probably calls it, “prime checkmating hour.” Rated or casual, victory doesn’t discriminate, with just an 8.33% difference in her winning chances.

Notable is her rivalry with usernames like cesaracb9 and josephrizal, with a solid nearly 89% win rate against the former and a perfect score against the latter. Opponents who fancy themselves “chess toughies” better watch out—Marianna’s record speaks volumes.

A Memorable Victory Snapshot:

On October 11, 2015, in a tense bullet match against joca23, Marianna showcased her tactical brilliance and time management. With a calm defense and sharp counterattacks in the Nimzowitsch-Larsen Attack, she emerged victorious when the opponent lost on time—a checkerboard mic drop moment!

Marianna Chierici is a player who combines disciplined strategy and flashes of tactical brilliance with a personality that keeps the chessboard alive and kicking. Whether grinding long endgames or blitzing past foes, she is a force in the chess world with a playful spirit and a penchant for the dramatic.
So next time you see Deletham (her username) on the board, remember: you’re not just facing an opponent; you’re entering the arena of a true chess artisan.

Hi Marianna!

You have a creative style with a clear preference for flexible flank set-ups (b3, g3, fianchettoed bishops) and unbalanced middlegames. Below is some personalized feedback based on your latest streak of games.

What you are already doing well

  • Piece activity in the middlegame. In your win vs. joca23 you quickly posted both bishops on strong diagonals and seized open files with Rc1-Rf1. That willingness to mobilise heavy pieces is a major asset.
  • King safety awareness. Whenever the position opens you usually remember to tuck the king away (e.g. 11 O-O in the win, 31 Kh8 as Black). This instinct keeps you in many fighting positions.
  • Technical conversion when ahead. Notice how smoothly you simplified into a winning rook endgame in the game against alehcim27 – excellent use of Rxh6 followed by promotion.

Primary areas for improvement

  1. Opening fundamentals
    • Early queen sorties such as 5 Qd2–4 Ke2 in the loss to palavari left your king in the centre and invited ...c5/…b5 breaks.
    • Aim for faster development and fewer pawn moves in the first 10 moves. A simple rule: try not to move the same piece twice unless you gain a clear tempo.
    • Spend a week reviewing model games in the Nimzo-Larsen Attack and Queen’s-Pawn structures so your plans feel automatic.
  2. Handling counter-attacks
    In several defeats you accepted material (e.g. 14 Rxe7 in the Scandinavian) without fully calculating the opponent’s initiative. Before grabbing pawns, ask yourself: “What is my opponent’s next threat?” and enforce the ‘two-question safety check’ (king & piece safety).
  3. Time management
    Six of your recent losses were on time from roughly equal positions. Try to reach move 20 with at least 20 seconds on the clock in 1|0 games; if you dip below, switch to simpler plans: centralise pieces, trade when safe, push connected passed pawns.
  4. Endgame accuracy
    In the Alekhine’s Defence loss you entered a rook endgame a pawn up but allowed counterplay with …h6/…a6. Study the “Lucena” and “Philidor” rook endings (search them in the chess.com drills menu) and practise converting with a 15-minute session each day.
