Constructive Feedback for Maria Florencia Fernández

What you are already doing well

  • Dynamic openings. As Black you rely on Pirc/Kings-Indian structures (…g6, …Bg7). These give you rich, double-edged middlegames that fit your tactical style.
  • Practical tactics. Your recent wins show confident combinations such as 24…Nd4! and pawn storms with …g5/…f4 that catch many opponents off guard.
  • Good fighting spirit. Even in worse positions you keep material on the board and look for counter-play instead of forcing exchanges.

Three priorities for the next training cycle

  1. Time management. You lost four of the last ten games on time from playable positions. Try these habits:
    ‑ Use the opening phase to “pre-move” known book moves.
    ‑ Adopt a simple counting rule: if your clock shows < 10 s you must either force a perpetual, liquidate to a trivially drawn ending, or simplify material immediately.
    ‑ Bullet-specific drills such as 1 | 0 arena streaks will improve your intuitive move speed without hurting accuracy.
  2. King safety in the King’s Indian.
    • In the Exchange line (E92) your …h6/…g5 plan gave White a permanent hook on h4 and the f-file opened against you.
    • Compare your choice with the standard plan …c6, …a5, …Be6 followed by …d5, keeping the g-pawn back.
    Tip: Load a reference game by Radjabov or Gelfand and replay till move 20 daily for a week; pattern recognition will replace guesswork.
  3. Conversion technique in winning endgames. In your victory over PartyPandaBear you needed 40 extra moves to convert a rook & pawn ending a piece up. Adopt the “four-step” checklist:
    1. Activate king
    2. Fix opponent’s pawns on one colour
    3. Create & advance passed pawn
    4. Use zugzwang & zwischenzug ideas to force capitulation
    10-minute daily end-game studies (e.g. rook vs pawns) will pay big dividends.

Opening micro-targets (next 30 games)

As WhiteAs Black
Play 10 games with 1.d4 c6 2.c4 d5 and practice the Panov plans. Replace 1…d6 with 1…e6 vs ­1.d4 three times to test the Queen’s-Indian / …Bb4+ set-up. This broadens your position types and reduces predictability.

Next steps

  • Schedule two sparring sessions this week where you start from the diagram after 10.O-O-O in the Exchange KID and play each side twice.
  • Finish one Chess.com Puzzle Rush daily until you consistently score ≥ 34; this sharpens the quick tactics you rely on in bullet.
  • Send me two games where you felt in control throughout; we will mine them for “best practices” to replicate.

¡Sigue así, Flor! Small, focused tweaks will convert many of those near-misses into clean wins.
