Mariana Sawae Kikuchi Cadilhac

Woman FIDE Master

Mariana Sawae Kikuchi Cadilhac, known in the chess world as marianacadilhac, is a formidable Woman FIDE Master who has mastered the art of balancing brainpower with a dash of charm. With a peak bullet rating of 2093 achieved in September 2024, Mariana has shown a relentless pursuit of excellence across all time formats—with a blitz peak nearing 1960 and a rapid peak north of 1649. The daily format may be slower, but it’s clear she prefers the adrenaline rush of faster games where her tactical kite soars to new heights!

Playing Style & Strengths

With an endgame frequency of 77.44%, Mariana clearly enjoys the long strategic marches of chess battles – no lightning-fast resignations here (her early resignation rate is a modest 2.7%). Her average winning game stretches to about 72 moves, proving patience and perseverance are her allies.
A true comeback queen, Mariana boasts a staggering 80% comeback rate when down on the scoreboard and keeps fighting even after losing a piece, winning almost half of those games. Tilt? A mere 12%, which means she keeps her cool like a grandmaster sipping tea while the opponent loses their queen.

Opening Moves: The Secret Weapons

When it comes to openings, Mariana’s “Top Secret” strategy reigns supreme with a hefty arsenal of over 1700 bullet games under her belt and a win rate around 46%. She is also no stranger to the Old Benoni Defense – a risky but rewarding choice – where she maintains a winning rate of over 62% in bullet play. Her repertoire spans Caro Kann variations and Queen’s Pawn systems too, showcasing versatility and a love for positional trickery.

Recent Battles and Highlights

As of June 2025, Mariana continues to sharpen her skills on Chess.com, engaging in thrilling battles that test her mettle to the limit. One notable recent victory saw her outlast her opponent in a Queen’s Pawn Opening Accelerated London Steinitz Countergambit, securing a win on time after a tense 51-move endgame duel. Whether winning on time, by resignation, or checkmate, her tenacity shines through.
Of course, no warrior wins every duel; she’s had her shares of defeats, demonstrating that even great players respect the learning journey where each loss is a stepping stone for future glory.

Fun Facts & Trivia

  • Mariana’s best recorded hour of play is around 5:00 AM — early mornings may just be her secret weapon!
  • Her win rate tends to slightly favor playing with the white pieces at about 47%, proving she knows how to make the first move count.
  • Mariana has a habit of hammering out long games averaging over 70 moves, so opponents beware: this isn’t a sprint, it’s a marathon.

In summary, Mariana is the perfect blend of fighter and strategist, a dedicated chess player with a penchant for endurance battles and tactical comebacks. Whether she’s blazing through bullet games or crafting quiet victories in blitz, one thing is clear: underestimating marianacadilhac is not on anyone’s to-do list.

Keep an eye on this rising star—she just might checkmate you before you realize what happened!

Hi Mariana!

Great streak yesterday – four wins against 2000+ in one sitting! Below is a concise review of what is already working well and what you can sharpen next.

What you are doing well

  • Active openings with d-pawns and the Caro-Kann  – you regularly reach middlegames you understand. Your miniature against magncarls18 (15 moves!) shows confident handling of the Semi-Slav structures.
  • Tactical alertness once the initiative is yours. The QGA win versus dollarbrain77 is full of accurate forcing moves after 12…O-O-O?!.
  • Good practical sense in worse positions. Several victories on the black side of the London came from stubborn defense followed by counter-punching (…c5 & …c4).

Main growth areas

  1. Clock management
    Five of the last seven losses were on time – often in equal or better positions. ⚑
  2. Early tactical hygiene
    a) 5…Bxd1? in the QGA (loss vs Etete2) dropped your queen.
    b) 15…Rxf2!! (you as Black) mated your king in the Semi-Slav (vs Zulia-vzla).
    Common thread: under-estimating forcing moves before castling or with queens on the board.
  3. Conversion technique in endgames
    The drawn-but-lost rook ending vs magncarls18 shows hesitancy activating the king and pushing passed pawns.

Action plan for the next two weeks

Time usagePlay 10 | 5 instead of 1 | 0 & 3 | 0 for at least 20 games~3 h

Illustrative tactical slip

White to move after 15…Rxf2!! – a reminder to keep the back-rank covered:


Ask yourself before every capture: “What is my opponent’s most forcing reply?”

Opening menu – next small tweaks

  • Queen’s Gambit Accepted (White): after 4…Bg4 prefer 5.Qb3 instead of 5.Bxc4 to keep the queen safe and hit b7.
  • London-vs-…c5: your setup with …c4 & …b5 (Black) is solid; add the manoeuvre …Ra6-b6 sooner to pressure b2.
  • Caro-Kann (Black): vs 4.Bd3 lines, play 4…Bf5 early to avoid space squeeze seen against magncarls18.

Encouragement

You already show 2100-level understanding when initiative and time are on your side. Trim the early blunders and late-game time pressure, and a stable 2100+ blitz/rapid rating is absolutely within reach.

Keep enjoying every game and feel free to send me any positions you find puzzling.
