Hi Mariana!

Great streak yesterday – four wins against 2000+ in one sitting! Below is a concise review of what is already working well and what you can sharpen next.

What you are doing well

  • Active openings with d-pawns and the Caro-Kann  – you regularly reach middlegames you understand. Your miniature against magncarls18 (15 moves!) shows confident handling of the Semi-Slav structures.
  • Tactical alertness once the initiative is yours. The QGA win versus dollarbrain77 is full of accurate forcing moves after 12…O-O-O?!.
  • Good practical sense in worse positions. Several victories on the black side of the London came from stubborn defense followed by counter-punching (…c5 & …c4).

Main growth areas

  1. Clock management
    Five of the last seven losses were on time – often in equal or better positions. ⚑
  2. Early tactical hygiene
    a) 5…Bxd1? in the QGA (loss vs Etete2) dropped your queen.
    b) 15…Rxf2!! (you as Black) mated your king in the Semi-Slav (vs Zulia-vzla).
    Common thread: under-estimating forcing moves before castling or with queens on the board.
  3. Conversion technique in endgames
    The drawn-but-lost rook ending vs magncarls18 shows hesitancy activating the king and pushing passed pawns.

Action plan for the next two weeks

ThemeConcrete taskTime
Time usagePlay 10 | 5 instead of 1 | 0 & 3 | 0 for at least 20 games~3 h
Tactics safety25 puzzles/day, set to “Training → Defensive Blunders” mode20 min/day
Opening repairAdd 6…h6 line in the QGA to avoid 5…Bxd1 traps; review three model games40 min
EndgamesStudy Chapter 3 of “100 Endgames You Must Know” (rook vs pawns). Test with lichess studies.1 h

Illustrative tactical slip

White to move after 15…Rxf2!! – a reminder to keep the back-rank covered:


Ask yourself before every capture: “What is my opponent’s most forcing reply?”

Opening menu – next small tweaks

  • Queen’s Gambit Accepted (White): after 4…Bg4 prefer 5.Qb3 instead of 5.Bxc4 to keep the queen safe and hit b7.
  • London-vs-…c5: your setup with …c4 & …b5 (Black) is solid; add the manoeuvre …Ra6-b6 sooner to pressure b2.
  • Caro-Kann (Black): vs 4.Bd3 lines, play 4…Bf5 early to avoid space squeeze seen against magncarls18.

Encouragement

You already show 2100-level understanding when initiative and time are on your side. Trim the early blunders and late-game time pressure, and a stable 2100+ blitz/rapid rating is absolutely within reach.

Keep enjoying every game and feel free to send me any positions you find puzzling.
