Train
Train chess tactics with unlimited free puzzles, drill a single motif like forks or pins, or turn your own blunders into puzzles from a game review.
Tactics puzzles
Unlimited puzzles from real games. Your rating adapts as you solve, and nothing needs an account.
Your own mistakes
Review a game and Chesslume turns the moves that cost you the most into puzzles — the tactics you personally keep missing.
Woodpecker method
Solve a fixed set of puzzles, then solve the same set again. The repetition is the point — you get faster and more certain on patterns you have already seen.
Sparring
Play a full game against Stockfish, handicapped to a rating band that actually makes mistakes at your level.
Opening trainer
Play real openings line by line — the board answers, and a clean line stays learned. 73 courses, from the Sicilian to the London.
Drill one motif
Same puzzle pool, filtered to a single pattern. Useful when you already know which tactic keeps getting past you.
- ForkOne piece, two targets, and your opponent can only save one.
- PinA pinned piece is on the board but not in the game.
- SkewerA pin backwards: the big piece is in front, and it has to move.
- Discovered attackThe piece that moves is not the piece that does the damage.
- Hanging pieceThe most common way games are decided is the simplest one.
- DeflectionThe defender is doing a job. Give it a better offer.
- Back-rank mateThe pawns that shelter the king are also the walls of its cell.
- Mate in 2Two moves, no escape, every defence covered.
Why train your own games
Solving random puzzles builds pattern recognition, but it does not tell you which patterns you are actually losing to. A rated player who drops games to back-rank tricks gains more from twenty back-rank positions than from two hundred mixed ones. The fastest route is to review your own games first, find the motif that keeps recurring, then drill that motif here.
