Daily puzzles
Five positions from real games, easiest first. Each one has exactly one move that is clearly better than everything else on the board — the engine checked every alternative before it was published.

Puzzles are mined from finished games. Play a few — against the bot is fine — and a set will appear.
Where these come from
Every puzzle is a real position from a finished game, shown from one seat's point of view — the opponent's hand is hidden here exactly as it was hidden then. A tactic whose answer turns on a card you cannot see is not a tactic.
The position carries no match id, no player names and no history: what is published is a board and a question, and nothing on it points back at the game it came from.
