Bernardo Vainzoff Sztokbant (Username: MFBerna)

Meet Bernardo Vainzoff Sztokbant, a chess virtuoso who proudly holds the title of FIDE Master. Known in the chess community as MFBerna, Bernardo combines strategic brilliance with a sprinkle of humor, proving that you can be dangerously good at chess and still laugh at a missed fork.

Rating Highlights

  • Peak Blitz Rating: An astounding 2700 achieved in March 2025, proving lightning-fast moves are Bernardo’s natural habitat.
  • Best Bullet Rating: A fierce 2618, evidence of fearless play where every second counts.
  • Top Rapid Rating: Strong and steady at 2604, a perfect balance of speed and thought.
  • Daily Chess Peak: Steadied at an impressive 2176 back in 2015, showing longevity and dedication.

Playing Style & Personality

Bernardo is no stranger to intense endgames, with a remarkable 75% endgame frequency, solidifying him as a player who thrives when the board is bare and the stakes are high. When losing a piece, Bernardo's comeback rate of nearly 78% shows a resilience that could inspire novels (or at least great commentary).

Beware if playing MFBerna around 10 AM – statistics show he peaks his game then, while his 'tilt factor' is modest at 20, meaning he keeps cool even if you try to unleash the dreaded “Blunder Storm.” Also, his average game length is about 73 moves, so settle in for a strategic marathon rather than a sprint!

Favorite Openings

Bernardo displays affection for some classical and secretive lines:

  • Unknown Opening in daily and blitz games—because mystery is the spice of chess life.
  • Top Secret openings with near 50% win rate—just don’t ask what those moves are.
  • Not to brag, but average win rates across others like French Defense and Caro-Kann suggest he enjoys keeping opponents guessing – or bewildered.

Recent Battles

Bernardo’s latest conquest was a thrilling win against 00000Daniel on June 3, 2025, featuring a precise Sicilian Defense - Mengarini Variation where resignation was the polite way out for the opponent after an 28-move tango. Of course, every victory is celebrated modestly — right after a quick rematch challenge!

Losses come and go, as with his recent match against michael124667, but rest assured MFBerna’s spirit remains unbroken – after all, it's just another opportunity to analyze and smile at that missed tactic.

In Summary

Bernardo Vainzoff Sztokbant is a resilient, technically skilled, and humorously self-aware chess player who favors deep strategic battles and storms the board with fast, aggressive play when it counts. Whether playing rapid, blitz, bullet, or daily, Bernardo’s goal is clear: dominate with skill, delight with style, and never forget to enjoy the game.

Positive Aspects

Bernardo, your recent games demonstrate several strengths worth highlighting:

  • Proactive Early Play: In your recent win using the Reti Opening, you capitalized aggressively on early tactical opportunities — such as capturing the pawn early and gaining active piece play.
  • Strong Endgame Awareness: Your last won game showed good conversion skills, pushing passed pawns and coordinating pieces to press the opponent until they lost on time.
  • Consistent Opening Repertoire: You have a diverse yet focused opening portfolio including Caro-Kann Defense, London System, Scandinavian Defense, and others, with respectable win rates across these openings.
  • Good Time Management Early On: The moves are generally made at a consistent pace, showing sound clock management in the initial phases of your blitz games.

Areas for Improvement

To continue advancing your performance, consider focusing on these aspects:

  • Handling Middle Game Transitions: In your recent losses, some turning points occurred in the middlegame where the opposition obtained better piece activity and structural advantages. Working on plan formulation in the middle game could improve your resilience.
  • Avoiding Critical Tactical Oversights: Some losses involved missing opponent tactics or falling for strong counterattacks. Enhancing tactical visualization and regular puzzle training can help reduce such errors.
  • Opening Move Precision: While your opening knowledge is solid, continuing to deepen understanding in your primary openings especially the Caro-Kann and London System variations would likely yield better positions and reduce early disadvantages.
  • Time Pressure Handling: Although you won a game on opponent time loss, blitz often leads to time scramble. Practice playing under clock pressure to maintain move quality until the end.

Long-Term Strategy

Your broader rating and performance trends indicate consistent improvement over the past months with a strong upward slope, despite a minor recent rating dip. To build on this:

  • Keep reinforcing your openings repertoire and supplement it with typical tactical and strategic plans to confidently handle emerging positions.
  • Regularly analyze your losses to identify recurring mistakes, especially relating to middle game tactics and transitions.
  • Enhance endgame technique through focused training; your recent success in endgames shows this can be a forte to exploit.
  • Consider playing slower time control games occasionally to improve deep calculation and strategic judgment, which will benefit blitz performance.
