About Beniamin Kasztanowiec (HikaruNiekaru00)

Beniamin Kasztanowiec, also known online as HikaruNiekaru00, is a fast-talking, faster-moving chess player who prefers the adrenaline-rush of Bullet chess. A grinder by night and an opening experimenter by day, Beniamin has climbed from casual club skirmishes to triple-digit peak ratings that would make a coffee-fueled speedster smile. He’s best known for quick tactical swerves, stubborn endgames and an almost suspiciously consistent comeback ability.

  • Preferred time control: Bullet — the blitz of breathless knights and hurried queens.
  • Peak highlights: 2344 (2026-01-20), 2272 (2026-02-02), 2347 (2026-02-26).
  • Active and growing: rating activity shows big gains in 2024–2026 with intensive play across formats.

Career Highlights & Totals

Beniamin’s career reads like a long, entertaining series of quick finishes and marathon comeback wins. Here are some tallies that tell the story at a glance:

  • Blitz record: 1,576 wins / 1,328 losses / 244 draws — a tireless presence on the 3–5 minute battlefield.
  • Rapid record: 658 wins / 483 losses / 74 draws — measured play with surprising tactical bursts.
  • Bullet record: 623 wins / 468 losses / 80 draws — preferred arena and often where the magic happens.
  • Daily/Correspondence: 607 wins / 481 losses / 11 draws — solid, patient play when the clock is kind.

Playing Style & Strengths

Beniamin mixes stubborn endgame endurance with sharp tactical instincts — think marathon stamina wrapped in a speedster’s reflexes. He often drags opponents into long endgames and is surprisingly hard to finish off once into a technical phase.

  • Endgame frequency: high — many battles go the distance (EndgameFrequency ≈ 63%).
  • Average moves per win: ~63; per loss: ~68 — games tend to be substantive, not one-move flukes.
  • Tactical grit: Comeback rate ≈ 75% — turns losing positions into wins more often than most.
  • Psychology: Best time of day to challenge him is around 09:00; TiltFactor suggests emotional swings after long streaks.

Favorite Openings (and where he shines)

Beniamin is a devoted student of the French Defense family and several quirky sidelines, depending on whether he’s in a measured Rapid game or a knife-fight Bullet.

  • French Defense (various lines) — a staple in Blitz/Bullet: French Defense.
  • Australian Defense — surprisingly positive results as White and Black: Australian Defense.
  • English Opening — effective in Bullet, often used to steer games into familiar middlegame structures: English Opening.
  • Amar Gambit & Amazon Attack — flavourful choices; used as surprise weapons in faster time controls.
