Free-play board · Engine analysis · Full move history
Sometimes you just want a board. Practice Mode is exactly that: drop into any starting position, play through it move by move, and use the engine to check critical moments along the way. Undo, redo, and full move history make it easy to explore variations without losing your place.
Use it to test out an opening idea you read about, replay a game from your own database, or try a position your coach asked you to study. It is the simplest mode on the site and one of the most useful.
