Start here if you're new

Chess has a small set of rules and one very long tail of exceptions. The core takes about twenty minutes to learn: how each piece moves, that the goal is to trap the enemy king, and that you cannot make a move leaving your own king in check.

Then there are four rules that catch out nearly every beginner, all worth learning properly rather than discovering mid-game:

  • Castling — the one move where two pieces move at once, and the conditions under which it's forbidden.
  • En passant — the pawn capture that looks illegal until you know it, and must be played immediately or the right is lost.
  • Promotion — a pawn reaching the far rank becomes any piece you choose, and it doesn't have to be a queen.
  • Stalemate — no legal move and not in check is a draw, not a win. More winning positions are thrown away to this than to any other rule.

Beyond those, the draws worth knowing are threefold repetition, the fifty-move rule and insufficient material.

A training routine that actually works

Improvement is mostly about the review, not the volume. A loop that works at any level:

  1. Play slow games. Rapid or longer. Blitz entrenches habits; it doesn't build them.
  2. Review every game you lose — before playing another. Find the one move where the position turned.
  3. Classify the mistake. Hung piece, missed tactic, no plan, time trouble. The category that keeps recurring is your study topic.
  4. Drill that one thing until it stops appearing.

Nearly everyone inverts this — heavy on new material, light on review — and then wonders why a thousand games changed nothing. The player who reviews ten games learns more than the player who plays a hundred.

Reading and writing moves

Algebraic notation is worth an afternoon early on. Without it you can't read a book, follow an annotated game, or review your own play — so it quietly caps how much everything else can teach you.
