about this question:
Allow me to explain that if the 'coach' is not the tournament itself, they
have access to exactly the same information (or possibly less) as
yourself, thus if you wish to trust their judgement, that is your choice.
However, it is poor poker etiquette, and to be fair to all players at the
table, I do recommend that rather than having a coach assisting with you
during an event, that you perhaps review the hand histories after the
event with your coach.
If you have any more questions or concerns, please don't hesitate to

I think, like Dorkus says, it's pretty much unenforcable anyways so the most they do is discourage it.
