Overview of your blitz progress

You have shown very positive short‑term gains recently. In the last month your rating rose by 77 points, and over the last three months your rating improved by 121 points, with a six‑month gain of 107. However, the twelve‑month trend is slightly negative, which suggests there have been ups and downs over a longer period. Your overall strength adjusted win rate sits around 50%, indicating you’re almost breaking even and there’s clear room to push your results over the 55–60% range to sustain growth.

What you are doing well

  • Consistent improvement in the near term: the 1‑ and 3‑month changes show you’re adapting well and locking in gains during recent sessions.
  • Solid results in certain openings: your performance in the Italian Game: Two Knights Defense (about 54% wins) and the Slav Defense: Bonet Gambit (about 55% wins) suggests you can handle sharper, dynamic lines with good practical play.
  • Diverse opening handling: you’re willing to test a variety of systems, which helps you learn different types of positions and avoid becoming too predictable.

Areas to improve

  • Convert advantages consistently in blitz: your strength adjusted win rate being near 50% indicates you often find moments to press but sometimes fail to convert, especially in time pressure or late middlegame endgames.
  • Endgame technique under time pressure: many blitz games reach simplified or rook endings where precise technique matters. Sharpening rook and minor piece endgames can increase your conversion rate.
  • Time management and move ordering: in several long tactical sequences you can refine how you pace your responses to keep pressure on your opponent without getting into time trouble.
  • Repertoire curation for blitz: while your results are solid in some openings, others (like the London System variant shown in openings data) are less successful. Streamline to fewer, well-understood lines to reduce on-the-spot decision fatigue.

Opening recommendations based on your data

  • Lean into your strengths: Italian Game: Two Knights and Slav Defense: Bonet Gambit are performing well for you. Consider expanding these lines with focused study (typical plans, key moves, and common pitfalls) to build a reliable blitz repertoire.
  • Minimize heavy reliance on weaker lines: the London System: Poisoned Pawn Variation shows a lower win rate. If you use it, pair it with solid, well-understood middlegame ideas or limit its use to opponents you know well.
  • Balance your white and black choices: complement your strong openings with two solid secondary options for both sides so you can adapt to the opponent’s choices without sacrificing consistency.
  • Study typical tactical motifs in your common openings: focus on themes that frequently arise in your best lines (knight maneuvers, central breaks, and typical pawn structures) to speed up calculation in blitz.

Practical plan to raise your blitz level (4 weeks)

  • Week 1 — tighten time management and tactical pace:
    • Do 15–20 minutes of tactics daily to reinforce pattern recognition.
    • Play a small batch of blitz games (3–6 per day) with a strict 3+2 or 5+0 time control to practice quick decision making.
    • Review 2–3 losses focusing on the moment you lost the initiative or blundered under time pressure.
  • Week 2 — reinforce your best openings:
    • Deepen study of Italian Two Knights and Slav Bonet Gambit: learn typical plans, common traps, and how to convert small advantages.
    • Keep London System usage light unless you’re comfortable with its typical middlegame themes.
  • Week 3 — endgame and conversion:
    • Practice rook endings and minor piece endgames with 1–2 practice sessions per week (short endgame drills or puzzle‑style endgames).
    • Play 2–3 practice blitz games focusing on maintaining pressure and converting slight advantages.
  • Week 4 — simulation and review:
    • Run a mini‑tournament: 6 blitz games with a clock target and review every game for a quick win‑loss pattern (where you spent too long, or missed a stronger plan).
    • Prepare a compact one‑page repertoire summary for your two main openings for white and two for black.

Summary and next steps

You’ve shown reliable near‑term improvement and have identified openings that suit your style. Focus on converting advantages, sharpening endgames, and consolidating a compact opening repertoire. With consistent practice, aim to push your strength‑adjusted win rate above 55% in the next 4–6 weeks and keep tracking your month‑to‑month trend to stay on a positive trajectory.
