Domestic abuse is a crime, and there is a civic duty to report it. I don't know the details but in the most serious cases, it can be illegal not to, and the law protects those who do. Having an opinion is not a crime neither is being straight, gay or whatever you can think of as long as it is safe, sane and consensual. And generally, when a kid shows strategic thinking, the school tells the parents about it and the chess club. There may be reasons why parents don't want their kid to play chess, and if it is not part of the curriculum, it is not something for the school to decide, they can make suggestions but parents have the final word. Also, noticing strategic thinking does not need to involve spying. If the chess coach looked as search histories for recruitment, that would be a problem.
