Chess Online: rules and examples
Open Chess Online, check the instructions and begin a round. Checkmate the opposing king. Check the relevant rule before repeating a move. Begin with the local / basic computer mode shown on the page. Choose a clear next step rather than rushing through the instructions.
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.
One thing to notice as you play
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
Understand the aim
Checkmate the opposing king. Use the instructions to see which actions move you towards it. The example below illustrates a decision.
A walkthrough of the rules
- 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.
Using the playing area
Tap a piece and target; choose a promotion piece when needed. A careful first action helps you become familiar with the layout. Look at the feedback after the action.
One way to understand the rules
Castling cannot pass through an attacked square. Apply the same reasoning to the position in your own round. Read the matching step again.
Keep this in mind
The computer is a small search opponent, not a rated engine. Take a moment to reassess the position before continuing. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
