Ultimate Three Card Poker

Introduction

Ultimate Three Card Poker is a variation on Three Card Poker I first noticed at the Silver Legacy in Reno on Feb. 26, 2010.

If you already know the rules for regular Three Card Poker, the rules for Ultimate Three Card Poker are the same, except:

  • The player may raise up to 3x his Ante bet if he has a pair or better.
  • The player must make an additional Blind bet, which most of the time will push or lose.
  • The player does not automatically win one unit if the dealer does not qualify; he still has to beat the dealer to win.
  • A winning raise bet pays even money only.


Rules

  1. A single 52-card deck is used.
  2. Hands are ranked in the following order, from highest to lowest:
    • Mini royal flush (suited AKQ)
    • Straight flush
    • Three of a kind
    • Straight
    • Flush
    • Pair
    • Ace high or less
  3. Play starts with the player making Ante and Blind bets, which must be equal. The player may also make a Pairplus bet, which is explained later.
  4. The player and dealer will each receive three cards. The dealer cards will be dealt face down.
  5. The player must decide to fold or raise. If the player has less than a pair, then the raise bet must be equal to the Ante bet. If the player has a pair or greater, then the raise bet must be equal to at least the Ante bet, and no more than three times the Ante bet.
  6. After the players have acted, the dealer will turn over his cards. If the dealer has a queen high or better, then the dealer will "qualify."
  7. The player's hand will be compared to the dealer's hand, and the one with the higher poker value shall win.
  8. The following is how each bet shall be adjudicated.

    Ante: If the dealer qualifies then the higher hand shall win. Ties push and wins pay even money. If the dealer does not qualify then the Ante shall push.
    Raise: The higher hand shall win. Ties push and wins pay even money.
    Blind: The higher hand shall win. Wins pay as follows:

    Blind Pay Table

    Quinella Pays
    Mini royal 100 to 1
    Straight flush 20 to 1
    Three of a kind 10 to 1
    Straight 2 to 1
    Flush 1 to 1
    Pair or less Push

  9. The Pairplus bet pays according to the poker value of the player's hand only. I have an unconfirmed report that the following pay table is used.

    Blind Pay Table

    Quinella Pays
    Mini royal 50 to 1
    Straight flush 40 to 1
    Three of a kind 30 to 1
    Straight 6 to 1
    Flush 4 to 1
    Pair 1 to 1
    Ace high or less Loss

Strategy

  • Fold with any hand less than J74
  • Raise 1x with better than J74 but less than pair
  • Raise 3x with a pair of better

Analysis

The following table shows the probability and contribution to the return for all possible outcomes. The "pays" column shows the combined win between the Ante, Blind, and Raise bets.
