Once your 5 cards are dealt, there is only one decision to make: Whether to
Fold,
Play, or
Triple Down. Here's the basic strategy (as analyzed by
Stanley Ko and documented on
Wizard of Odds):
TRIPLE DOWN:
anytime you have a pair of aces or better.
FOLD:
anytime your hand is worse than King, Queen, Eight, Four (K-Q-8-4).
PLAY: with all other hands. In other words, whenever your hand is better than K-Q-8-4 and worse than a pair of aces.
Example:
FOLD THIS:
