So what's your take on promo chip payment. And, do you think or know how many HOUSE favorites are gifted in?
I think it is 100% invitational. The awards are generally table tickets that you play until you lose, so they are 99% as good as cash.
It depends on the kind of promo chips. If they are the "play until you lose" kind they are just like real chips and you should play them the way you would play real money. If they are the "play once" kind, then it's a whole new ball game and the best choice may surprise you. See http://www.blackjackforumonline.com/content/beyondcouponsbjfo.pdf In the article, Grosjean calls the first kind "non cashable chips" and the second kind "funny chips".
