texas shootout: A beatable game??

[Piz0wn0reD!!!!!!]

there is a game dealt in a nearby casino called texas shootout. can someone do the math to see if this game is beatable? this is how it works:

The game uses a 6 deck shoe. Players make a bet, the dealer deals 4 cards to each player 4 to the dealer. Players pick the best holdem hand and throw away the other 2, then the dealer picks the best hand (based on a chart) and a board is dealt. Each hand that beats the dealers hand wins. The only edge that the house pushes (assuming you dont vary from the house rules of hand picking) is in a push, or if you make "bonus bets" (which are clearly huge sucker bets and i wont bother to describe the payouts). Any player can "chop" their hand: they can play 2 hands out of the 4 dealt to them and they must match their original bet for the new hand. Because of this option i would think this game is beatable. Am i right? one of you super math guys should work thisw out. I will try to locate the dealers hand chart and post it if that helps.
