I'm not sure about the coaching being allowed, but I think it should not be allowed. Poker is an individual game and should be played like so. One of the dynamics of the game, that makes it interesting and less about luck, is the skill level each player has.
I look at it similar to being in school. You go to school to learn and it is your responsibility to retain the information given to you. Your teacher doesn't sit next to you and coach you will you take your examinations and if you get outside help it is considered cheating. Whatever knowledge you accumulated in your mind prior to the test is what you have to use. So if you don't know the answer to question number 11 then you don't know it you can leave it blank or guess.
So whatever knowledge you have of poker when you play you just apply it and if you don't know what to do in a certain situation my advice is to fold. Or you can take the other option "guess" which usually translates to going all-in, but i don't suggest that if you don't know what your doing
I think they should make a rule against coaching in all honesty.
