Quick summary

Nice stretch of blitz results. You are converting small advantages into wins and finishing games cleanly when you get a passed pawn or active rooks. At the same time a few tactical oversights and occasional king safety lapses are costing you sharp games. Below are focused, practical suggestions to keep improving in blitz.

What you do well

  • Creating and advancing passed pawns. Your wins show strong instinct for turning pawn majorities into decisive assets.
  • Rook activity and endgame technique. You coordinate rooks and kings well in the late middlegame and endgame to convert advantages.
  • Tactical finishing. When a promotion or mating net becomes available you calculate and execute it efficiently.
  • Opening consistency in chosen systems. Your performance with the English Opening and several English/Alapin/Accelerated Dragon lines is solid — you get playable middlegames out of the opening.

Most important areas to improve

  • Simple tactical oversights in the middlegame. A few losses come from missing a decisive knight jump or a quiet mate threat. Slow down on checks for opponent threats before you move.
  • King safety when you go for active play. Some attacking choices leave your own king exposed to forks or surprise mates. Prioritize one extra defensive move when the position sharpens.
  • Time management in critical moments. In blitz it is tempting to push too fast; a few seconds of thought on candidate moves stops obvious tactical refutations.
  • Selective endgame study. You win many rook-and-pawn races but a few endgames slip away after a trade or two. Drill common rook endgames and king+pawn promotion techniques.

Concrete training plan (weekly)

  • Daily (15–20 min): Tactics themes that cost you games — knight forks, back-rank patterns, quiet discovered checks. Use mixed drills but add targeted sets (knight forks x50).
  • 3× week (30 min): Endgame routine — Lucena and simple rook endgames, king activity, and pawn promotion technique. Practice converting a passed rook pawn under opposition pressure.
  • 2× week (30 min): Rapid opening review — pick 2–3 favorite lines from your top openings (for example the variations you already play well). Keep short note of typical plans and one middlegame plan per line.
  • Post-session review (10–15 min): After each blitz session, quickly review losses and one close win. Focus on the critical error and write a one-line takeaway.
  • Blitz habit: before every move in sharp positions ask yourself two questions — "what is my opponent threatening?" and "what tactic changes the evaluation immediately?"

Game-specific notes (review these positions)

  • Decisive endgame win — review this game to see how you turned a small material edge into a passed pawn and promotion: Review the endgame conversion. Key takeaway: excellent king activity and rook infiltration. Also note how exchanging minor pieces simplified the path to a passed pawn.
  • Promotion finish — you converted an advanced h-pawn into mate after patient pressure: See the promotion tactic here. Key takeaway: coordinate heavy pieces with pawn storms; also check your safeguards so a counterattack cannot stop the passer.
  • Loss by surprise mate — this game shows the tactical oversight to fix: Study the mating sequence you missed. Key takeaway: when material is unbalanced and the opponent has active pieces, explicitly scan for quiet knight checks and mating squares around your king.

Short checklist for your next blitz session

  • Before you move in sharp positions, spend 3–6 seconds scanning for opponent threats and forks.
  • If you have a passed pawn, simplify into a clear plan: activate king, remove blocking pieces, and create a promotion square.
  • If you are attacking, ask whether your own king becomes exposed after one more tempo of aggression. If yes, defend first then attack.
  • After any loss, mark the decisive blunder and practice a short tactical set that addresses that motif.

Next steps I recommend

  • Run a focused 2-week routine: daily tactics + three endgame sessions. Re-evaluate progress with one analysed session per week.
  • Keep building on openings where you already score well. Make one short file with typical pawn structures and target plans for each main line.
  • Send me one loss you want deeper feedback on and I will give a short annotated plan for improvement.

Extras

If you want, I can produce a brief annotated line by line analysis for any of the games above or create a tactical drill set focused on the motifs that caused your losses. You can also open the opponent profiles quickly: Aradhya Garg and Phuong Hanh Luong.
