Quick summary

Nice run in blitz — steady rating climb and a healthy win rate against comparable opposition. Your recent games show good tactical vision and the ability to convert advantages, but also some recurring practical weaknesses under time pressure and in certain opening lines.

• Strength-adjusted win rate: ~0.611 — solid for blitz.
• Fast rating gain: +97 over the recent period — you’re improving quickly.
• Most reliable openings: Petrov's Defense and some French lines (Burn/Burn Variation).

What you’re doing well

Highlights from your wins and overall play:

• Finishing ability: you frequently convert tactical or material edges into wins (examples include decisive rook/queen infiltration and forcing mating nets).
• Active piece play: you use rook lifts and queen penetrations effectively to create final threats.
• Opening preparation pays off in some systems — your Petrov results are particularly good (high win rate).
• Endgame technique: you convert passed pawns and rook endgames reliably in several games.

Recurring weaknesses to fix

Patterns observed in losses and in close games:

• Time management: a few wins were on time rather than decisive play — try to avoid relying on opponents flagging. Practice keeping 10–20 seconds for critical decisions in the late middle game.
• Tunnel vision in complex positions: missed defensive resources and checks (leading to mates or big material losses). Before each move, run a quick "checks, captures, threats" checklist.
• Vulnerable king moments: in some games your king got exposed on the queenside or back rank (watch for back-rank issues and weak pawn pushes around your king).
• Inconsistent results in certain openings: English/Agincourt and Four Knights show low win rates — either refine those lines or avoid them in blitz until you feel comfortable.

Concrete, actionable improvements

Short drills and habits you can use immediately.

• Tactics every day: 15–30 minutes of mixed tactics — focus on forks, pins, discovered attacks, and back-rank tactics. Blitz outcomes are decided by tactics.
• 5-minute practice with deliberate pauses: play rapid training games (5+3) where you force yourself to take 2–3 extra seconds on each critical move to build better calculation under pressure.
• Pre-move safety check: develop a habit — before you premove or play fast, run three fast checks: (1) are you leaving the king in check? (2) did you hang a piece? (3) is there an opponent check/capture you missed?
• Opening triage: keep the lines where you score well (Petrov's Defense, French Defense: Burn Variation) and prune the low-performing ones (English, Four Knights) until you have clearer plans in them.
• Postgame routine: after every loss, note the exact moment things turned (tactical miss, time trouble, opening mishap). Two lessons per game is a good cap — be specific (e.g., “missed knight fork on move 23”).

Study & training plan (4-week blitz focus)

Simple weekly plan to keep momentum while fixing leaks.

• Week 1 — Tactics + Time control: 20–30 min tactics per day + 10 blitz games at 3+2 focusing on the checks/captures/threats checklist.
• Week 2 — Openings consolidation: 3 sessions of targeted study (30–40 min) on your best openings (Petrov's Defense, French Defense): common plans, one tidy line each to use in blitz.
• Week 3 — Endgames & technique: 3 short endgame sessions (rook pawns, passed pawns, basic king + pawn vs king) + 10 rapid games (10+5) to practice converting advantages with more time.
• Week 4 — Mixed: mix tactics, 5 rapid games, analyze two recent losses (identify exact move where evaluation flips) and add one small opening novelty or anti-line to your repertoire.

Practical blitz tips

In-game habits that help immediately:

• When ahead on the clock and position, simplify: trade pieces (not pawns) — simplicity wins in blitz.
• Use checks/captures/threats filter before each move — it takes 2–3 seconds but avoids many blunders.
• Prefer safe active moves over speculative sacrifices in time trouble. If you must calculate a long combination, spend a chunk of time early rather than in zero seconds later.
• If your opponent has mating threats, first ask "Can I interpose? Can I trade queens? Can I escape?" — repeating this saved several of your past games.

Openings: what to keep and what to fix

Your opening performance shows clear winners and weaker lines:

• Keep: Petrov's Defense (strong score), French Defense: Burn Variation (100% in small sample).
• Refine or temporarily avoid in blitz: English Opening: Agincourt Defense and Four Knights Game — work on concrete plans, not just moves.
• Tip: prepare one "trouble-free" anti-line per weak opening (a simple sideline that avoids deep theory and leads to playable middlegames).

Example: a clean finish to review

Here’s a recent win with a strong final tactic — study the buildup and the Rh3→h8 idea. Replay it to see how activity and pressure forced resignation.

• Game snippet (you as White):
• Key moment: you created a direct mating threat by lifting the rook and concentrating pieces against the king — good demonstration of converting initiative into decisive tactics.

Suggested immediate checklist before each game

• Warm-up: 5–10 tactics to wake up pattern recognition.
• Decide opening pair for the session (one main, one safe backup).
• Set a simple rule: in time trouble, prioritize king safety and trade pieces if ahead.

Follow-up

If you want, I can:

• Analyze one loss move-by-move (post the game you want reviewed).
• Create a 4-week personalized training schedule with daily drills.
• Generate 100 tactics targeted to the motifs you miss most (forks, back-rank, discovered attacks).
