Eihartze Buiza Prieto (aka BuiiChess)

Meet Eihartze Buiza Prieto, a Woman FIDE Master whose chess journey is anything but boring. With a keen mind and a penchant for tactical theatrics, Eihartze has carved a place in the chess world that's as impressive as it is entertaining. Whether facing a fierce blitz battle or a rapid-fire bullet round, Eihartze shows an unwavering determination – often surrendering to neither time nor opponent.

Rating Highlights

  • Bullet peak rating: 2109 (2022)
  • Blitz peak rating: 2264 (2021)
  • Rapid perfect win rate: 100% (all 23 games won!)

Playing Style & Stats

Known for an endgame frequency near 62%, Eihartze prefers battles that stretch into the late hours of the game, turning complicated positions into sweet victories. Despite sometimes reluctantly throwing in the towel early (early resignation rate around 24%), the comebacks are astonishing, boasting a 67.6% comeback rate. When a piece goes missing, Eihartze’s win rate zooms to an impressive 76%, proving that losing a pawn is just the start of a dramatic comeback.

With an average win clocking in at over 54 moves, patience truly is a virtue for this player. Strategic mind meets psychological resilience — although a tilt factor of 8 hints that even chess warriors have their moments of “What just happened?!”.

Notable Records & Fun Facts

  • Favorite time to play: mornings around 9 AM, where the win rate shoots up to a dazzling 80%.
  • Enjoys a solid winning streak too — longest is 13 games, current streak happily continues at 4.
  • Likes playing with the white pieces a bit more, winning almost 60% of the time, but black isn’t far behind.
  • BuiiChess tends to give less mercy to certain opponents, racking up several 100% win rates against multiple online challengers – chess players beware!

When not on the digital battlefield, Eihartze might just be plotting the next brilliant move or polishing that unstoppable opening repertoire (shh… it’s “Top Secret”). But one thing’s clear: with Eihartze at the board, surprises are guaranteed, and checkmate is always just a few tactics away.

Feedback for Eihartze Buiza Prieto

Dear Eihartze,

You've shown solid understanding and strategic awareness in many of your recent games. Here are some key points to help you continue improving your chess skills:

Strengths

  • Opening Knowledge: Your repertoire, including Sicilian and Ruy Lopez variations, shows good preparation. You handle complex positions well and often reach active piece play early in the game.
  • Tactical Awareness: In winning games, you’ve demonstrated sharp tactical vision — for instance, exploiting pins and skewers effectively, and timing attacks such as sacrifices on h6 and tactical shots in the middlegame.
  • Endgame Technique: When converting advantages, you remain calm, showing good endgame technique and positional understanding to press for a win or maintain winning chances.

Areas to Work On

  • Time Management: There were a few games lost due to time pressure, so improving your clock management will be valuable. Try to balance spending time on critical decisions with keeping enough to avoid rushed moves in complex positions.
  • Defensive Play: Some losses show opportunities to improve your defensive resilience, especially in counterattacks or under pressure. Focus on maintaining piece coordination and avoiding passive moves that can lead to overwhelming activity for your opponent.
  • Calculation Accuracy: While your tactical vision is good, double-checking calculations in critical positions can help reduce blunders, especially in complicated middlegame situations.
  • Positional Planning: Exploring deeper plans in quieter positions could help you build more sustainable advantages. Sometimes more prophylactic moves or better piece placement can prevent opponent counterplay before initiating attacks.

Suggestions for Improvement

  • Study classical games in your favorite openings to strengthen your grasp of strategic themes.
  • Practice puzzles focused on tactics, especially endgame tactical motifs, to sharpen calculation under time pressure.
  • Analyze losses, focusing on where you lost the initiative or fell behind in development, and consider alternative moves.
  • Play slow time control games occasionally to develop patience and more thorough calculation.

Keep up the great work, and continue enjoying your chess journey!
