I noticed Triple Action Hold 'Em at Binion's Horseshoe on May 1, 2009. It is also offered at Internet casinos using Cryptologic software. It is a fairly simple poker based game, where you go against the dealer. What makes this game different from the recent batch of poker variants is this one is based on five cards, and uses only a 28-card deck.
Rules
A modified 28-card deck is used, consisting only of the eights to aces.
Play starts with three bets available to the player, the Ante, Flop Bet, and Bonus Bet.
The dealer will deal each player, and himself, two hole cards. In addition, there is one three-card flop, which is dealt face down. The players' hole cards are dealt face down, while the dealer's cards are dealt one up and one down.
The player must either make a Raise bet or fold. The Raise bet must be equal to the Ante bet. If the player folds, then he loses his Ante wager.
The dealer turns exposed his other hole card and the flop.
If the dealer's five-card poker hand is a pair of nines or greater, then he shall qualify.
If the dealer does not qualify, then the ante bet shall pay even money, and the raise shall push.
If the dealer does qualify, then the player's five-card poker hand will be compared to the dealer's; the higher hand wins. If the player has the higher hand, then the Ante and Raise shall pay even money. If the dealer has the higher hand, then the Ante and Raise shall lose. An exact tie results in a push.
If the player did not fold, and his hand is a full house or better, then he shall be paid an Ante Bonus, according to the pay table below, which is based on the amount of the Ante wager. It is not required to beat the dealer for purposes of the Ante Bonus.
Regardless of who wins between the player and dealer, the Flop and Bonus bets shall pay according to the pay tables below. I presume that if the player folds, he still can win the Bonus bet.

Strategy
The optimal strategy on the Ante bet is to always raise. Of the three bets, the element of risk is lowest on the Ante bet, at 1.82%. I often get asked about the optimal mixture of bets for games like this. In this case, it is 100% on the Ante, and 0% on the Flop and Bonus bets.

The overall return on the Ante bet is -0.071758 + 0.035409 = -0.036349. So the house edge is 3.63%. The player should always raise, so the average final bet is two units, making the element of risk = 3.63%/2 = 1.82%.
