Choose a tactical theme to practise, from mate in one to forks and pins.
Every chess puzzle contains a tactical opportunity. Start by looking for checks, captures and threats, then calculate your opponent’s best reply. Solve the daily puzzle as a quick routine, or practise one theme until you recognise the pattern in your own games.
Theme practice does not affect your rating. Play in the Puzzle League when you want to compete, or review a completed game and practise the positions where you made mistakes.
