Thank you for the kind words. It would be perfectly acceptable to give advice in that situation. In general, it is acceptable to give solicited advice, even to strangers. The dealers don’t like it when a player gives unsolicited advice. It gets into a grey area if it isn’t clear whom a player is soliciting advice from. If the player seems to be asking the dealer, then you shouldn’t advise. When in doubt, my policy is to keep my mouth shut.
