Why use Free Chess Trainer?

Opening-focused training

The trainer is built specifically for openings: you start from known positions and are asked to find the next move in your line. No full-game clutter – just pure opening practice.

Real lines from real games

Lines are derived from open databases such as the Lichess opening explorer. You get practical, modern lines instead of purely theoretical engine lines.

Spaced repetition ready

Under the hood, the trainer tracks how often you get a position right. This allows us to prioritize moves you struggle with and repeat them more often over time.

Fast, lightweight, and private

Everything runs in your browser. There is no login, no cloud account, and no backend database. Your progress is stored locally using localStorage, and you can clear it at any time.

How it works

  1. Pick an opening. Go to the Openings section or open the Trainer and choose an opening like the French Defense or Sicilian Defense.
  2. The trainer shows a position. You’ll see a real position from your chosen line, just before your move.
  3. You play your move on the board. Drag and drop or tap the squares – no hints unless you ask for them.
  4. Get instant feedback. The trainer tells you if your move matches the line and can auto-advance to the next card when you’re correct.

Open the Trainer

Lightweight by design

Free Chess Trainer is intentionally simple. It’s designed to be something you can open on a laptop or tablet, run a few lines before a game, and close. No distractions, no social features, just focused training.
