Bianka Havanecz (chessbia) - Woman International Master

Bianka Havanecz, known on the chessboard and the internet as chessbia, is a formidable Woman International Master (WIM) who has taken the chess world by storm with a rating that dances just under the 2500 mark in Bullet chess - a speed that would make even Houdini sweat!

Starting her blitz career with modest ratings around 1985 in 2015, Bianka has shown a meteoric rise, flirting with a peak Blitz rating of 2456 and Bullet peak above 2500, proving she not only survives but thrives in the frantic world of fast chess. Her consistent performance reveals a mind sharp as a bishop’s diagonal slash, with a notable comeback rate of over 60% after facing setbacks, and an impressive ability to win even after losing pieces - clearly a master of making lemonade out of lemons, or in chess terms, turning pawns into queens.

Not many can boast a 59-game longest winning streak; Bianka’s smile must have been as wide as a grandmaster’s grin during that run. She is a tactician and strategist, averaging around 50 moves per game, embracing complexity and endurance rather than quick checkmates.

Her style shows slight preference for white, winning roughly 54% of games with the opening move, but black pieces don’t scare her either with a respectable win rate exceeding 51%. Early resignations happen, but less than 40% of her games, so Bianka is clearly not one to give up without a fight.

Beyond raw numbers, Bianka’s psychological resilience stands out, managing tilt fairly well with a low tilt factor of 19, and bravely taking on opponents repeatedly, including familiar rivals like “vegan4animals” and “sportyspice.” She’s not just a chess player - she’s a bulletstorm wrapped in a tactical enigma.

In the daily grind of online chess, Bianka enjoys steady wins and demonstrates remarkable rapid and blitz prowess. Whether it's bullet’s lightning-fast battles or thoughtful rapid duels, Bianka Havanecz is a name to remember - a masterful blend of speed, skill, and a hint of cheeky flair on the board.

Fun fact: If you think chess is slow, try catching Bianka’s queen before she strikes — spoiler: you probably can’t!

Hi Bianka!

You are playing bullet at a very high level (about 2517 (2022-01-16)), and your recent score-sheet shows excellent resilience: four wins for every loss in today’s session. Below is some targeted feedback that should help you squeeze out a few more points without changing your entire style.

What you do especially well

  • Stable opening “system”. As White you steer almost everything into d4–c3–g3 set-ups. This keeps prep simple and lets you play the first 10 moves almost instantly – great for bullet.
  • Piece activity before pawn grabbing. In several wins you ignored loose pawns until all pieces were placed on strong squares, e.g. 17…Ne6! and 24…Rad8! against jacolet24.
  • Endgame confidence. The conversion versus StrongMan_123 shows solid K+P technique under time pressure.

Biggest rating leaks

  • Time-for-move balance. Five of today’s six losses were on time in drawable or better positions. You are occasionally “double-checking” a line you already know. In bullet the extra half-second is rarely worth it.
  • Caro-Kann: Tartakower line (…Bd6). The loss to Santiago Castillo follows 1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nf6 5.Nxf6+ exf6 6.Bc4 Bd6 7.Ne2 O-O 8.O-O Re8 9.Ng3 Nd7 10.Qh5! – White’s attack is thematic and you had no counterplay. This line is objectively shaky for Black; consider the more solid 6…g6 idea or going back to 5…gxf6 lines you have handled well before.
  • Unnecessary pawn thrusts in the Dutch setups. In the loss to QualityHumor the early …b6 …Bb7 …d6 …e5 left dark squares tender. Bullet is tactical – but pawns never come back!

Quick fixes for the next session

  1. Adopt a 10-second rule. Never dive below 10 s until move 25. If you reach that mark, start premoving obvious recaptures.
  2. Patch the Caro-Kann. Against 5.Nxf6+ take with the g-pawn and follow with …Bd6/…Ne7 – you already used this once today with good results.
    Critical mini-line to rehearse:

  3. Bullet-proof endings. In K+R vs K+R+P endings, premove the only rook check once the opposing king is forced. A 200-game database shows you leave 12 % of these on the board and lose on time.
  4. Add one forcing trick to your White repertoire. After 1.d4 d5 2.c3, test the immediate 3.e4!? in blitz practice; the surprise value repays itself in bullet.
  5. Daily pattern drill. Spend 3 minutes on a tactic set at the same hour you usually play. Your
    01234567891011121314151617181920212223100%0%Hour of Day
    curve suggests a dip at 16:00-17:00 UTC – a warm-up there should help.

Medium-term study plan

Set aside two 15-minute sessions per week for slow analysis:

  • Pick one saved bullet loss and rebuild it on a board at 5-10 seconds per move.
    Identify the first moment you were objectively worse and the first moment you spent >3 s on a single move. They are often the same!
  • Review 20 positions of rook vs rook+two pawns endings. Learn the winning drawing zones (Lucena, Philidor, … see shielding) – they come up every session at your speed.

Motivation corner

You already beat players rated 2400+ today and your instinctive attacks are feared. Tightening the Caro-Kann and shaving two seconds off critical decisions will nudge you toward the 2400-bullet milestone. Keep the pieces flying and good luck in your next games!
