The major platforms have child modes or privacy settings that limit contact. The names differ, the substance is the same - check these when creating the account.
Explain one simple rule separately: never move from the chess site to another messenger with someone they do not know in person. That closes off nearly the whole class of risks.
It is also worth telling a child that suspecting the opponent after every loss is a bad habit: it gets in the way of learning from your own mistakes.
The question is less about the number of minutes than about what the child is actually doing. Half an hour of puzzles and half an hour of bullet are very different half-hours.
A warning sign: the child plays faster and faster, game after game, with no pauses and no interest in the result. That is no longer chess but a tapping habit - the cure is switching to puzzles and to live events.
An online rating updates after every game, which is convenient for motivation and hard on a child who reads a falling number as a verdict.
The same rule serves adults well: a run of losses usually signals tiredness rather than a drop in level.
Children who play only online often surprise coaches: a decent rating and complete disorientation at their first live event.
The working arrangement: online for puzzles and volume, live events every month or two for real progress - when to enter a first tournament.
Five sentences that head off most problems. Say them once when the account is created - and repeat them a month later.
And the main thing from the parent's side: take an interest in the games rather than the rating. «Show me how you won?» does more for a child's relationship with chess than any screen time control.
Yes, with the basic settings in place: private messages and chat off, a username with no personal data, an avatar that is not a photograph, and the account registered on a parent's email. The key rule for the child is never to move from the chess site to another messenger with a stranger.
Agree on a number of games rather than minutes: «three games» is a clear boundary, whereas half an hour always cuts across a game in progress. Puzzles and rapid are more useful than blitz, and bullet is worth limiting - it is addictive and teaches little at beginner level.
Agree in advance that the child does not reply but shows you and presses the report button. Better still, switch chat off in the settings: there is no useful conversation there for a child.
Explain that ratings fluctuate for everyone, including the strongest players, and do not compare theirs with other people's - numbers are not comparable across platforms. Praise a mistake found rather than points gained, and introduce a rule: after two losses in a row, play stops for the day.
Live events are needed. Children who only play online get lost at their first over-the-board tournament: a different board, a clock in their hands, a living opponent and no way to start again. Combine online puzzles and volume with an event every month or two.
There are no club or arbiter roles in the app: the create button is available to everyone. You can announce a tournament today and run it this weekend.
when there are more than ten players and nobody should be knocked out
when the field is small and fairness matters most
when you simply want to get together and play
The bot is constantly improved based on real tournaments. If you need a feature that isn't there yet, message the developers right inside the bot with the /support command. Many features appeared exactly because organizers asked for them, and useful ideas get added quickly.
For parents - what chess really gives children, what age to start. Online - choosing a platform, fair play.
