Hmm...I'm not really a fan of telling players to fold certain hands from certain positions. I mean telling them without explaining why because that will confuse them.
Not playing AJ from BB has to do with you being OOP and AJ being a hand that can be dominated by a strong range. But this hand is playable from BB if you have good reads on the BTN.
Anyway, I just feel you need to explain your reasoning instead of just telling them what to do.
