A mate-in-one puzzle has a single move that ends the game immediately. These are the entry point to tactical training: they build the habit of scanning every check before considering anything else, which is the same habit that finds long forcing sequences later.
List every check available in the position, then test each one for escape squares, blocks, and captures of the checking piece. Mate in one is always among the checks, so the search is finite.
This trainer draws on 1,139 puzzles tagged with the mate in 1 theme, rated from 399 to 2000 with a median of 936. Every position comes from a real game in the Lichess open puzzle database, so the tactics are ones that actually occurred over the board rather than composed studies.
