Playing style

Funny, stubborn and endgame-happy — Shayan loves long fights. Opponents might win material early, then find themselves slowly outplayed over dozens of moves.

  • Endgame frequency: 82.12% — prefers the attritional route.
  • Avg moves per win: ~75.4; per loss: ~73.9 — games go long.
  • Comeback rate: 88.62% — excellent at salvaging games after setbacks.
  • Best time to play: around 22:00 (prime comeback hour).
  • Tactical edge: wins often follow gritty, persistent play rather than lightning tactics.

Quick summary

Nice run, Shayan — you're converting well and your recent daily games show confident play in the Dutch-style structures and good endgame sense. Below I highlight what you do well, where you can sharpen things, and a compact training plan to keep the upward trend going.

View the most recent win (study this game)

Replay the whole game and step through candidate moves before checking the engine — focus on where the balance shifted in the middlegame.

Opponent: iraj-hajebabaee

What you're doing well

  • Strong opening choices in the Dutch-family setups and similar pawn-structure systems — you get comfortable middlegame plans and generate consistent play (see Dutch Defense).
  • Good conversion: you turn advantages into decisive endgames and your opponents often resign when you simplify correctly.
  • Tactical awareness in messy positions — you spot checks, captures and forcing sequences that win material or create decisive threats.
  • You switch between attack and simplification effectively: when you can trade into a winning endgame you do so instead of overcomplicating.

Areas to improve (concrete examples)

  • King safety when pushing kingside pawns. In the Feb 29 game you played ...g5 and later the h-file opened — that gave your opponent a tempo to snatch the h-pawn with their queen. Try to calculate the consequences of pawn storms near your own king and only push when you have adequate cover.
  • Pawn structure clarity after exchanges. Several games show you accepting doubled or isolated pawns to gain activity — that’s fine, but make a clear plan for them (blockade, minority attack, or piece exchanges). Work on converting imbalanced pawn structures into concrete plans.
  • Candidate move habit. In a few critical moments you picked a forcing tactical line quickly (good), but sometimes one quieter candidate would have improved your position more. Before committing, pause and list 2–3 candidate moves — especially in complex middlegames.
  • Endgame technique depth. You convert well at the practical level, but practice key rook and minor-piece endgames (e.g., Lucena, basic king+pawn races) to boost confidence in tighter conversions.

Short training plan (next 4 weeks)

  • Daily: 15 tactical puzzles (focus forks, discovered attacks and mating nets). Aim for accuracy, not just speed.
  • 3× per week: 1 annotated game from your recent wins. Write down your candidate moves before checking — then compare with engine and note recurring mistakes.
  • Weekly: 2 endgame exercises. Start with rook endings and basic pawn races (Lucena/Ramirez patterns) until conversion technique feels automatic.
  • Openings: pick one main line in your Dutch/Caro setups and learn the typical pawn breaks and piece placements. Use the short term to memorize plans rather than long theory lines (see Dutch Defense and Caro-Kann Defense).

Medium & long term goals

  • In 2–3 months: reduce tactical errors by tracking “mistake types” from annotated games (e.g., missed forks, hanging pieces, overlooking checks).
  • In 6 months: expand your repertoire so you can play both Dutch-style structures and a reliable back-up opening; this prevents opponents from steering you into uncomfortable lines.
  • Work toward mastering 10 typical endgame positions and 20 recurring middlegame plans from your favorite openings.

Concrete drills — do these for 20–30 minutes/day

  • 10 tactics (mixed motifs) — mark the ones you miss and do them again the next day.
  • 5 minutes: quick review of your last daily game — write one thing you did well and one thing to avoid next time.
  • 10 minutes: one endgame position (practice playing both sides until you convert or defend correctly).

Small tips for your next games

  • Before each daily game, set one goal: “I will not lose material to simple forks” or “I will keep king safety before pawn storms.”
  • When you see an opponent grab a wing pawn (for example h-pawn), immediately check whether that opens lines to your king or gives them counterplay — if yes, refrain from further weakening moves.
  • Use the daily time control: spend your extra hours on critical branches rather than on obvious moves early in the game.

Follow-up

If you want, send one game you lost recently and I’ll annotate the key turning points with suggested candidate moves and short drills tailored to the mistakes found. You can also ask for a focused plan on any opening (for example Dutch Defense or Caro-Kann Defense).
