Chess Tactics Trainer

Yes. The chess.lc tactics trainer is 100% free, runs entirely in your browser, and requires no install, no signup, no account, and no credit card. There are no daily puzzle caps, no rating-gated content, no watermarks, and no premium tier — open the page and start solving immediately. Every one of the 30 puzzles is unlocked from the start.

A chess tactics trainer presents positions with a winning combination — your job is to find the key move. Studying tactics is the single highest-ROI improvement activity for players under ~2000: roughly 90% of decisive games below master level are decided by a tactical motif (a fork, pin, skewer, discovered attack, or back-rank mate) rather than by deep strategy. Solving 5–10 puzzles a day builds pattern-recognition that lets you find these motifs over the board in seconds.

The 30 puzzles cover the full tactical catalogue: knight fork, queen fork, royal fork, back-rank mate, smothered mate (Philidor's legacy), discovered attack, discovered double check, x-ray attack, skewer, bishop skewer, absolute pin, relative pin, removing the defender, deflection, promotion tactics with =Q / =N underpromotion, Arabian Mate (rook + knight), Anastasia's Mate (rook + knight on the edge), Fool's Mate, Scholar's Mate, Damiano's Mate, kiss-of-death queen mate, two bishops mate, lawnmower (ladder) mate with two rooks, hook mate (rook + pawn + knight), and queen-plus-bishop battery mates. Each puzzle is labelled with its motif so you can drill specific patterns.

Click any of your pieces — its legal moves light up as dots on empty squares and ring outlines on capturable pieces. Click a highlighted destination to play the move. If it matches the winning tactic, the solution explanation appears and a 'Next Puzzle' button advances you. If not, the attempt counter ticks up and you can keep trying — there's no time limit and no penalty for wrong guesses. You can also jump to any of the 30 puzzles directly from the 'Tactics covered' grid below the board.

These are the named checkmate patterns covered in the trainer. A 'lawnmower' (or 'ladder') mate uses two rooks to drive the enemy king to the edge — one rook cuts off a rank, the other delivers check on the next, and they alternate. A 'hook mate' is a rook delivering check supported by a pawn (so the king can't capture the rook), with a knight covering the king's only escape square — pawn, knight, and rook form a 'hook' shape. An 'Arabian mate' is a rook + knight pinning the king to the corner: the knight blocks escape squares while the rook delivers mate on the edge.

No. The trainer is purely click-based: you select a piece, see its legal moves highlighted, and click a destination. You never type a move. After you solve a puzzle, the solution is shown in standard algebraic notation (SAN — e.g. 'Nxe6+' or 'Qh7#') with a plain-English explanation, so you'll passively learn notation as you solve. The board also shows file letters (a–h) and rank numbers (1–8) on the edges.

Yes. The board, piece highlights, puzzle info panel, and the 30-puzzle theme grid are all fully responsive — the layout reflows from side-by-side on desktop to stacked vertical on mobile, and the chess squares scale up to be comfortably tap-friendly on phones. There are no browser plugins, no app install, and no minimum screen size. Works on iOS Safari, Android Chrome, and any modern desktop browser.

Once you've solved the puzzles here, the next step is to spot the same motifs in your own games. Upload any PGN to chess.rodeo for unlimited free Stockfish analysis — the engine flags every missed tactic with a forced-move evaluation drop, so you'll see exactly which forks, pins, and back-rank mates you walked past in real games. No account, no daily cap, no premium tier, no paywall on engine depth or multi-PV.
