Profile: Leszek Filipiak
Highlight: big experience in Bullet, fearless opening choices, and a remarkable comeback instinct.
Playing style
Fast, opportunistic, and stubbornly tactical. Leszek often converts small advantages into full points under severe time pressure and has a habit of complicating positions to leverage his speed and pattern recognition.
- Preferred time control: Bullet
- High comeback rate and strong performance after material loss
- Average decisive game length: ~51 moves — decisive but not reckless
- Rare early resignations; fights in messy endgames
Career highlights
- Huge game totals in Bullet and Blitz; tens of thousands of Bullet games overall.
- Long winning streaks (longest: 74 wins) and several peak months in 2024–2025. 2410 (2025-07-05) 2523 (2025-10-05) 2304 (2025-07-04)
- Best hours: late night and early morning — opponents beware at 02:00.
Openings & repertoire
Leszek favors flexible and tension-rich systems. His repertoire emphasizes the English Opening (King's English Variations), Alapin lines against the Sicilian, and dynamic Benoni setups.
- English Opening — King's English Variation (frequent, very successful). English Opening

Fun facts & habits
- Username: doktorlech83 — a handle opponents learn quickly to respect.

- Tilt factor is moderate; overall resilience is high.
- Enjoys long streaks of focused play — and occasionally tweets at his mouse pad when a tactic fizzles.
Quick summary
Leszek — nice string of wins. You're consistently getting strong positions out of the opening (especially the English), creating tactical chances, and you win a lot of games on the clock. Your 1‑month rating jump (+201) and high opening win rates show you're playing well. Below are focused, practical points to keep improving in bullet.
- Keep leaning on the English Opening — it's your best weapon (English Opening).
- You win a lot by pressure + time edge. That’s a skill — preserve it, but don't rely on it alone.
- Targeted practice will convert more of your wins into sustainable rating gains instead of streaks.
What you're doing well
Concrete strengths visible in the recent games and your stats:
- Strong opening preparation and comfort in the English family — high win rates and quick good development make your middlegames easier to play.
- Good sense for tactical opportunities: you spotted and executed decisive exchanges and sacrifices (examples in your recent wins where you snatched material or simplified into winning endings).
- Practical clock play: you often convert on time pressure, which is a very useful bullet skill.
- Good piece activity and attacking instincts — you push for initiative instead of passivity, which forces opponents into mistakes.
Reference: your recent win vs DRAVOKS shows a decisive tactical sequence and active pieces. Open the final position to review it:
Recurring problems to fix
These are patterns that show up in the recent loss and some tougher games.
- Poor time distribution late in games — several losses are "won on time" for the opponent. In bullet you must trade some accuracy for speed; still, avoid getting into long, unclear sequences with little clock.
- Occasional positional sloppiness when facing active counterplay (opponent rook lifts, back‑rank threats). In the loss to lukamagic73 you left black pieces active and ended up with a tactical squeeze and time trouble.
- Tendency to go for complicated continuations when a simpler, safe line preserves the advantage. Simplify when you have a time edge or clear material advantage.
- A few missed defensive resources — when your opponent creates threats, check quick defensive intermezzi instead of reacting passively.
Concrete drills & practice plan (weekly)
Short, focused training works best for bullet improvement.
-
- Daily 10–20 minutes: Tactics blitz (1 minute per puzzle) — pattern recognition beats calculation in bullet.
- 3× per week: 5 games vs slightly stronger opponents but with 15+5 or 10+5 to practice decision making with a little cushion. Focus on time management, not only winning.
- 2× per week: 15 minutes of opening review — pick 3 key English setups (one short plan for each of: symmetrical, reversed Sicilian structures, kingside attacking setups). Use model games and note typical pawn breaks and piece posts. (English Opening)
- Once a week: 30 minutes of speed endgame training — basic rook and pawn endgames and king activity. Many bullet wins are decided there if you keep time parity.
- One habit drill: play two sessions where you force yourself to spend no more than 2–3 seconds on "obvious" moves. This reduces overthinking in bullet.
Bullet‑specific tips (practical)
- Pre‑moves: use them in safe recaptures and forced recaptures only. Avoid speculative pre‑moves when the opponent can change the capture.
- When ahead on the clock, simplify: trade pieces and avoid long tactical complications that eat your time.
- When behind on the clock, seek forcing lines or perpetuals; a one‑move tactic that keeps the position complicated is rarely worth it if you're flagged.
- Keep king safety first — many quick losses in bullet stem from allowing back‑rank or mating nets while chasing material.
- Memorize 4–6 fast checkmating and defensive motifs (back‑rank, smothered mate ideas, common queen forks). They save seconds under pressure.
Opening advice — stick & deepen
Your stats show the English family is a clear edge for you. Instead of broadening to many systems, deepen the lines you already play:
- Consolidate the King’s English lines you win most often (English Opening: King\u0027s English Variation).
- Prepare 2–3 move orders against the Sicilian and French that you face frequently — common replies and how you want to simplify or keep tension.
- Build a short one‑page cheat sheet for each variation: typical pawn breaks, piece plans, and one tactical trick to look for. Review this before a session.
Short term goals (next 30 days)
- Reduce time‑loss defeats by 25%: add a timer discipline — stop the clock and take a breath before long sequences.
- Daily tactics: 20 puzzles per day for pattern speed.
- Convert one bad habit (e.g., unnecessary pre‑moves or playing on when losing on time) into a new habit (simple trades when up on clock).
Longer term plan (3 months)
Leverage your recent +70 to +201 momentum while fixing the 6‑month dip pattern.
- Solidify the English repertoire and add one reliable anti‑Sicilian reply.
- Make endgame basics automatic (king activity, Lucena, basic rook endings) so time pressure decisions are easier.
- Track your time‑loss games and aim to cut them by half — the fastest rating gains in bullet come from reducing flag losses.
