Hi Magdalena Kozak — quick summary

Nice run in blitz lately — your six‑month jump shows real improvement and you're converting many advantages. Below I’ll highlight what you do well, where to tighten up, and a compact training plan so each session pays off in your next games.

What you're doing well

  • Strong practical play in the opening: your results with sharp choices (Amar Gambit, Australian, several Sicilian lines) show you know how to create unbalanced positions and put pressure early.
  • Good endgame technique — multiple wins by resignation indicate you convert small advantages and simplify when ahead (keeps opponents uncomfortable in the clock fight).
  • Tactical vision under time pressure — many wins come from forcing sequences and timely piece sacrifices. Your strength‑adjusted win rate (~51.5%) is solid for blitz.
  • Resilient rating trend: +497 over 6 months and +54 in the last month — that’s progress, keep it up.

Key weaknesses to fix (high impact)

  • Time management: in several games you finish moves with only seconds left. With 1+2 or 3+0, that’s dangerous — you’re winning on opponent time sometimes rather than the position. Practice using the increment and avoid risky long think on non-critical moves.
  • Tactical oversights around knight forks and back‑rank checks. In your recent loss to zaher1235789 a knight jump (Ne7+) ended the game quickly — watch for squares you leave available to enemy knights when you push pawns or exchange defenders.
  • King safety after pawn moves: pushing g or f pawns can create holes. In some games you invited tactical strikes by loosening your kingside structure; be cautious when launching pawn storms without calculation.
  • Occasional passivity in middlegame piece placement — some openings where you aim for piece trades early leave you with fewer active plans when the opponent keeps pieces on.

Concrete, game‑level takeaways (from your recent PGNs)

  • Win vs kengorax — you played Rossolimo/fiancetto ideas and went for kingside pressure (g4, gxf5). That worked because you kept rooks active and punished back‑rank weaknesses. Review this game in a board viewer to see the swap decisions around move 30 that simplified into a win.
  • Loss vs zaher1235789 — tactical sequence around Nxf5/Ne7+ exploited loose squares. When you see opposite‑colored bishops or a knight headed to the 7th, double‑check candidate captures that open those paths.
  • You win many technical endgames — keep simplifying into those where you’re better but avoid premature exchanges when you still have a clear attack to press.

Targeted checklist to use during blitz games

  • Before each move: 1) any immediate checks or captures? 2) does my king have escape squares? 3) am I leaving a square for a knight fork? (quick 3‑question routine)
  • If you’re ahead on material: trade down to reduce tactics and use the clock advantage — don’t allow counterplay.
  • When you push pawns near your king (f/g/h), ask: which piece will guard the critical squares after trades?
  • Use the 2‑second increment: make harmless “book” moves fast so you retain time for complicated decisions.

Practical 4‑week blitz training plan

  • Daily (20–30 min): tactics trainer — focus on forks, pins, skewers, discovered checks. Short, frequent sessions build pattern recognition.
  • 3× week (30–45 min): review two recent losses and one close win — annotate with: candidate moves, why you picked a move, what you missed. Aim to replay each critical tactic until it’s obvious.
  • 2× week (60 min): one rapid game (15|10) where you force yourself to spend more time in the opening/middlegame — this improves decision quality that transfers back to blitz.
  • Weekly (30 min): endgame drills — basic king+pawn vs king, rook endgames, and simple minor piece endings. You already convert well; tighten the theoretical wins to be automatic.
  • Opening refinement: prioritize 1–2 sidelines. Keep your Amar Gambit/Australian toolbox and pick one Sicilian line (e.g., the Rossolimo/Closed line) to study typical plans rather than endless move memorization. Use Sicilian Defense as your anchor when reviewing plans.

Micro habits that give big results

  • Before pressing the mouse: glance for any enemy knight hops or back‑rank mates (takes 1–2 seconds).
  • Use pre‑moves only when no tactics exist — in messy positions pre‑moves often lose you the game.
  • After every blunder, write a single sentence: “I missed X because I didn’t check Y.” This speeds correction.

Next steps — quick checklist for your next 10 blitz games

  • Play 10 blitz games with the explicit goal: “no hanging pieces” — if you hang a piece, stop and review the mistake immediately.
  • Keep a simple log: one line per game documenting the deciding factor (time trouble / tactical miss / opening surprise / endgame conversion).
  • At the end of 10 games, pick the most common issue and run a focused 2‑week drill on it.

Resources & follow‑ups

  • If you want, send 2–3 games you felt unsure about and I’ll annotate the critical 3–5 moves for you (I can highlight tactical motifs and alternative candidates).
  • Study suggestion: 15 minutes of themed tactics (forks/pins/discovered checks) + one annotated game review per day for two weeks — this compounds quickly.

Final encouragement

Your rating trend and win totals show a player who learns from play and improves fast. Focus small (time use + tactical checklist) and you’ll see more stable wins instead of relying on opponent time trouble. If you want, I can prepare a 2‑week daily drill plan tailored to the Sicilian Rossolimo and the Amar Gambit — say the word and I’ll draft it.
