Chess Online: what to know before playing
Bring your attention to one round of Chess Online. Checkmate the opposing king. Choose a clear next step rather than rushing through the instructions. Begin with the local / basic computer mode shown on the page. Keep the game area visible while you use its controls.
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.
An idea for your next attempt
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Notice the feedback after each input.
The purpose of your moves
Checkmate the opposing king. An attractive position is not enough unless the goal is met. Take a moment to understand the current position.
Follow these playing steps
- 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.
Making selections and moves
Tap a piece and target; choose a promotion piece when needed. On a smaller screen, keep the active part of the board within view. Use one clear input at a time.
See the idea in action
Castling cannot pass through an attacked square. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
A mistake to avoid
The computer is a small search opponent, not a rated engine. Read the feedback to see why an action did not have the expected result. 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.
