Vojtěch Zwardon - International Master of Chess
Known in the chess world as Herracek, Vojtěch Zwardon is an International Master with a knack for blitz battles that could make even the most seasoned grandmasters raise an eyebrow. With a blitz rating soaring above 2700 at his peak in 2024, Vojtěch has proven he's not just a slow thinker — he's a speed demon who thrives under time pressure.
Starting his blitz journey with a rating around 1943 in 2017, Vojtěch quickly scaled the ladder, averaging over 2576 in 2024 and maintaining a fierce presence on the 64 squares. His bullet play, though more modest, boasts a respectable 78.9% win rate in the limited games he’s tackled, showing that when the clock ticks down to seconds, Herracek is no stranger to wild attacks or lightning-fast tactics.
Vojtěch doesn't just play; he dominates endings, with an endgame frequency of nearly 77%, proving patience combined with tactical awareness: an 87.9% comeback rate and an almost mythical 98.5% win rate after losing a piece. If you catch him tilting (only an 11% tilt factor, thank you), you're probably just lucky — or enjoy seeing a master get frustrated.
Fun fact: Vojtěch once held a 14-game winning streak in blitz — that's a whole symphony of pawns pirouetting to victory. While his current winning streak rests at a humble zero (even titans have off days), don’t be fooled: his average games per year tower in the thousands, proving a true gladiator who lives for the rush of every tick and tock.
Opponents beware! Whether it's a casual Sunday or a 1 AM brainwave session, Herracek’s win rate tends to hover around half his games, with a spike in the early morning hours where he hits over 60% wins. If your brain isn't fully awake yet, you might just find yourself on the short side of a swift and stylish checkmate.
With strategic moves, a penchant for long, thoughtful endgames, and an arsenal of openings he guards like chess fanatics guard their secrets ("Top Secret" with 48.8% wins in blistering blitz), Vojtěch Zwardon is a player to watch.
In short: he plays fast, thinks deep, and never resigns early — except maybe when the coffee runs out.
What you’re doing well in blitz
Vojtěch, you show a willingness to enter dynamic, tactical positions and keep the pressure on your opponent. Your willingness to explore sharp lines can lead to practical chances in blitz when you stay active and avoid passive games. You also adapt well to situations where the position stays lively and you look for chances to complicate the game rather than immediately simplifying.
Key improvement areas
- Time management: in fast games, you can get caught in complex moments. Practice quick, solid decision-making in the opening and aim to reach a clear middlegame plan within the first 15 moves.
- Calculation discipline in sharp lines: while tactical aggression is a strength, be careful with speculative sacrifices or long forcing lines that rely on exact moves. When unsure, seek simpler, safer continuations that retain pressure.
- Opening consistency: you’re exploring a wide repertoire, which is great for variety but can lead to awkward middlegame structures. Consider stabilizing 2–3 reliable lines and study their typical plans and common tactics.
- Endgame readiness: blitz often reaches tricky endgames quickly. Strengthen basic rook endings and simple minor-piece endgames so you can convert small advantages or hold draws more reliably when needed.
Targeted plan to level up
- Repertoire consolidation: choose 2 White lines and 2 Black responses that fit your style and study the main middlegame plans and typical pawn structures for those lines. Build a quick-reference cheat sheet with key ideas and typical moves.
- Daily tactical focus: solve 15 short puzzles (5–10 minutes) concentrating on common motifs like forks, pins, skewers, discovered attacks, and simple checkmates. This trains fast pattern recognition for blitz.
- Post-game reviews: after each blitz session, write a brief 3-point recap focusing on the biggest mistake, the correct plan you missed, and one thing you’ll do differently next time.
- Endgame drills: dedicate 1–2 sessions per week to basic endgames (rook endings, king activity in rook endings, simple knight vs bishop endings) so you can finish games cleanly even when under time pressure.
- Time-factored practice: simulate short time controls (3+2 or 5+0) while doing focused reviews to improve decision speed without sacrificing accuracy.
Openings focus
Your openings show a diverse curiosity and a readiness to press in dynamic lines. To convert that into consistent results, consider narrowing to a couple of robust setups that provide clear middlegame plans. For example, you seem comfortable with structured English Opening suites and related aggressive systems; pairing those with a few reliable Black replies can create steadier middlegame themes and fewer risky deviations under time pressure.
If you’d like, we can create a short, opening-focused study plan tailored to the lines you enjoy, with quick-reference ideas and typical middlegame plans. You can also explore quick references like: English Opening: Drill Variation or Sicilian: Nyezhmetdinov-Rossolimo Attack to keep your notes handy.
Next steps
- Tell me which 2 White lines and 2 Black replies you want to own for the next two weeks, and I’ll build a precise, day-by-day study schedule with short tasks and a sample practice PGN you can follow.
- If you want, I can generate a compact 2-week blitz improvement plan and a practice set of 5–10 quick puzzles each day tailored to your chosen openings.
- Send a quick note after your next blitz session with a short reflection on what felt hardest and what plan helped you stay calm during the clock.
