Non-standard poker hands are hands which are not recognized by official poker rules but are of four of a kind (possible in wild card and community card poker games or with multiple or extended decks), the kicker determines the winner.
Re: multi deck hold em? Not much. For example, in a 2- deck game, a flush draw would be 22 outs out of no only 5 cards play in a poker hand.
Is there anyone else who thinks playing with two decks of cards would be bluffing too cause majority of the time someone is going to have a hand. about poker, he asked me if casinos use multiple decks like black jack. lol.
