Open for "anyone"? Or open for "everyone"?
Is the tournament open for "anyone" or "everyone"?
Solution 1:
There's a subtle distinction, as noted that's likely unimportant -- unless you're at all concerned about subconscious reactions from speakers of American English.
"Anyone" does have some negative connotations and usages attached to it that people don't necessarily think about:
- "Anyone can do that."
- "They'll take anyone."
For your purposes either would probably be fine, but "everyone" will be perceived as more inclusive.
Solution 2:
The distinction is not important in this case. Everyone means every person, without exception and anyone means any person, without discrimination.
Solution 3:
Usually a tournament would be "open to everyone" or "open to anyone".
To me there is a marginal difference that "open to everyone" sounds slightly more friendly or more welcoming than "open to anyone".
