Your Current Profile

  • Peak bullet rating: 2904 (2023-08-03)
  • Typical opening choices: 1.Nf3 / d4 systems (Reti-London family) with White, Scandinavian & Queen’s Pawn defenses as Black.
  • Time control played most: 60″ (hyper-bullet).

What You’re Doing Well

  1. Quick tactical eye. Your recent wins show you spotting loose pieces (e.g. 17.Bxa8, 21.cxd5!) and mating nets (…Qh1#) in mere seconds.
  2. Flexible structure play. The London/Zukertort set-up lets you handle different Black plans without thinking long – ideal for hyper-bullet.
  3. Conversion when ahead. When you keep a safe clock margin, you finish cleanly; see your last win:

Main Pain-Points

  1. Clock management. 8 of your last 10 losses are on time with playable or even better positions. You often dip under 10 s around move 20 while opponents still have >20 s.
  2. Over-ambitious king hunts. Sequences like 17.Ng7⁺–20.Ng7⁺ burned 15 s and gave no material; meanwhile your own king became a target and you flagged.
  3. Narrow opening repertoire. The same London-style set-up appears in nearly every White game. Strong opponents (e.g. Jose Fabian Benito) prepared early …e5/…Bg4 plans and steered you into pawn-down endings.
  4. End-game technique under time pressure. Positions such as K+R vs K+R+P slipped because you kept premoving instead of activating the king or forcing a draw.

Targeted Recommendations

1. Time-Handling Drills

  • Adopt a move-per-second rule: never spend more than 2 s during the first 15 moves. Use a metronome or coach-bot to practise.
  • Premove only forced recaptures; for anything else use shift-click to schedule but cancel if the position changes.

2. Broaden Your First-Move Repertoire

  • Add a direct 1.e4 mini-repertoire (Scotch or Italian) so opponents cannot auto-prepare vs the London.
  • Against 1.d4 d5, test the Colle-Koltanowski for variety yet similar plans.

3. “Safety-First” Tactical Filters

  • Before launching a knight sacrifice, give yourself a 1-second blunder check: “What is my worst piece? What is his next check?” (You’ll avoid loops like Ng7⁺–Ng5.)
  • Review 3 puzzles daily that feature zwischenzug & windmill motifs; they recur often in bullet.

4. End-game Micro-Lessons

  • Memorize two key resources: Philidor (R+P vs R) and Lucena. These decide many of your flag losses.
  • Practise the “king walk” exercise: start with K+P vs K and win/draw vs computer in ≤10 s.

Next-Week Action Plan (15-minute daily)

  1. 5 min: Bullet opening warm-up (randomize between 1.e4, 1.Nf3, 1.d4).
  2. 5 min: Puzzle Rush survival – stop the run after one miss to train caution.
  3. 5 min: End-game bot – play K+R+P vs K+R with 10 s each side.

Stay consistent, track your clock usage, and enjoy the grind – small tweaks will convert many of those “lost on time” games into wins!
