I had never heard of this. I thought you must be mistaken. But according to wikipedia, casino hold'em "is played in over one hundred live casinos and over one thousand online Casinos worldwide"
from wiki: https://en.wikipedia.org/wiki/Casino_hold_%27em
Rules
The game is played with a standard 52 card deck.
Each player makes an Ante bet and may make an optional AA bonus side bet.
The player and dealer are both dealt two cards (face down).
Three cards are then dealt to the board and will eventually contain five cards.
After checking his/her cards, the player has to decide (a) to fold with no further play losing the Ante bet or (b) to make a Call bet of double the Ante bet.
If one or more players makes a Call bet the dealer will deal two more cards to the board, for a total of five.
Players and dealer make their best five card poker hand from their own two personal cards and five board cards.
Each player’s hand are compared with the dealer’s.
The dealer must have a pair of 4s or better to qualify.
If the dealer does not qualify, the Ante bet pays according to the AnteWin pay table and the Call bet is a push (stand off).
If the dealer qualifies, and the player's hand is better than the dealer's, the Ante bet pays according to the Ante-Win pay table and the Call bet pays 1 to 1.
If the dealer qualifies, and the dealer's hand is equal to the player's, all bets are push (it doesn't win or lose).
If the dealer qualifies, and the dealer's hand is better than the player's, the player loses all bets.
There is a version of Hold'em in the CardsChat Casino ("Casino" tab in white bar above). However, it's not played against a House hand, so the betting is different.
No. I copied the address bar from my browser (which pointed to the wiki page), then simply pasted it in my post. I have been having linking issues since Saturday (approx). Originally links would open in a new window. They are not doing that from a CC tab, for me, today.
