The Chess Online playbook
Use a short break to learn the rhythm of Chess Online. Checkmate the opposing king. Use the example below to understand a decision. Read the objective before making your first input. Look at what changes after your first action.
Play on one device with a friend or against the basic computer opponent. Repetition and the fifty-move rule trigger an automatic draw here; there is no internet matchmaking or tournament clock.
Try a more deliberate round
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Make the next step deliberately.
What you need to achieve
Checkmate the opposing king. Keep that objective in view throughout the round. Try to explain the aim in your own words.
Work through the instructions
- Select local play or basic computer.
- Choose a piece and a legal target.
- Castling, en passant and promotion obey king-safety rules.
- Use the promotion selector before moving to the last rank.
- Undo or New game restarts play.
Your inputs
Tap a piece and target; choose a promotion piece when needed. A careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.
A closer look at one example
Castling cannot pass through an attacked square. Compare this with the rule that governs the move. Notice the change in the playing area.
Where a round can go wrong
The computer is a small search opponent, not a rated engine. A different version of the game may use a different rule. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
