Quick overview
Nice session — you converted complex positions and finished cleanly in several games. Your recent streak shows strong practical finishing and growing confidence in blitz. Keep the momentum and focus on a few high‑impact habits (time management and Najdorf plans).
What you're doing well
- Endgame technique: you convert passed pawns and rook/endgame advantages reliably — king activity + connected pawns is a recurring strength.
- Practical play under pressure: you create straightforward plans and execute them in time trouble rather than getting lost in calculation.
- Opening repertoire balance: you steer games into structures you understand (Sicilian Defense: Closed, D\u00F6ry Defense, Sicilian Defense: Alapin Variation).
- Tactical finishing: you spot tactical wins and promotion tactics quickly, turning small advantages into decisive wins.
Main areas to improve
- Time management — at least one game ended on the clock. In equal or slightly better positions preserve a 15–20 second reserve and avoid long think on routine moves.
- Najdorf consistency — your Najdorf results are mixed. Focus on typical pawn breaks, piece placement and simple plans rather than memorizing long move sequences (Sicilian Defense: Najdorf Variation).
- Minimize small inaccuracies before simplifications — a couple of wins turned into longer technical fights because of one inaccurate exchange. Tighten calculation in the few moves before major trades.
- Reduce risky premoves in messy positions — premoves are fine in quiet positions but dangerous when checks/captures/promotions are possible for the opponent.
Game-specific tips (from your recent games)
- vs Damian Lewtak — excellent rook activity and marching connected passed pawns. When simplifying to rook endgames, centralize the king quickly and keep the rook active on the opponent’s back ranks.
- vs Antoni_Radzimski — great tactical sequence: you advanced a pawn to promotion and used the new queen to deliver mate. Practice spotting promotion routes and mating nets so you execute them faster in blitz.
- vs Piotr Brzezina — you maintained winning pressure while the opponent ran out of time. To avoid relying on flags, practice quiet technical conversions so the win comes earlier on the clock.
- vs Kaivalya Sandip Nagare — you lost on time in a complex middlegame. Decide early whether to simplify or complicate; if simplifying, play the straightforward plan and save time for later critical moves.
Concrete 4‑week blitz plan
- Daily (20–30 min)
- 15 min tactics (short mates, forks, pins, promotion tactics).
- 5–10 min endgame drills — rook vs rook+pawn, king/pawn basics, Lucena ideas.
- 3×/week (30–45 min)
- Work one opening line in depth: Najdorf practical plans and two model games — focus on typical pawn breaks and piece plans.
- Play 2–3 rapid (10+0 or 5+3) concentrating on time preservation and converting advantages quickly.
- Weekly
- One annotated session: pick 4 recent blitz games, mark the 5–10 critical moves and extract recurring mistakes to target next week.
Practical blitz checklist (use at the board)
- First 10 moves: stick to safe, familiar lines — avoid sharp new ideas unless you know the resulting structures.
- When ahead: trade pieces and keep the clock running. Don’t spend >20s on obvious moves.
- When behind: complicate only with concrete tactics; otherwise seek active piece play and avoid unilateral premoves.
- Always ask: "Is this move forcing?" If not, make a simple improving move and save time for forcing sequences.
Quick next steps
- Today: 15 min tactics + 10 min rook endgames, then play a 5+3 focusing on not flagging.
- This week: study two Najdorf model games with emphasis on the middlegame plans and pawn breaks.
- Send me two 6–12 move sequences from your games where you felt unsure and I’ll give move‑by‑move improvements.
Notes & offers
- Your strength‑adjusted win rate is solid — small, targeted improvements (time control + Najdorf plans) should raise your practical score.
- I can build a 2‑week tactical set tailored to the tactical themes you face most often and a short Najdorf checklist if you want — say the word and I’ll prepare it.
- Review opponents from the session: Damian Lewtak, Antoni_Radzimski, Piotr Brzezina, Kaivalya Sandip Nagare.
