In snooker, Jimmy White and Ronnie O'Sullivan.
In snooker its every player.
If a player is deemed to have not called a foul (e.g. accidentally feathering the cue ball) there are endless replays, debates and plenty of chat...because its so rare.
Tbh maybe the culture is different in the US, but in Europe it is expected that you call your own fouls in pool too, it would be rare for a player to knowingly foul and not point it out.
Not to say it never happens, but its pretty rare.
I assumed it would be the same in the US, i.e. players may genuinely not realise they've feathered the cue ball or something, but wouldn't deliberately not call a foul.
