Poker/Texas Holdem
Nothing like a game of cards to separate the pirates from the land lubbers! The flavor of Poker played here is called Texas Holdem.

Cheatin'
Unlike (we hope!) your local games you play with your friend, you can cheat at cards! If you get a card up your sleeve, you can swap it into your hand! Arrrrrr, now this be fun!!

Obtaining cards
There is a man Unknown in the Unknown tavern in Port Royale who will give you quest to win 150 gold. Luckily, you don't have to play until you're up 150 gold, just win 150 gold, and hopefully not lose much in the process! Return to him and he'll give you another quest to kill a skeleton. Run back over behind the town, kill any Sludge or Crud you see, and return to him once more. He'll give you a random card. You can repeat the quest and keep collecting as many cards as you like! Yes, you could potentially have all 52 cards up your sleeve at once!

Whats up your sleeve?
Now when you're playing your next hand, you'll see two options Swap first, and Swap second. Go ahead and pick one of these. You'll then see four buttons, Hearts Diamonds Clubs Spades If you have any cards of each type, the button will be enabled and you can select it. Choose a button. Now you'll see a button for each card. Again, anything you have up your sleeve will be enabled. Make a note of what card(s) you have up your sleeve. You can cancel the swap and go back to playing fair if you like.

Swapping cards
I would wait until you have a hand with a lot of gold riding on it before actually swapping in a card. You can either be sneaky enough and cheat or you can fail. Either way the card up your sleeve will be gone, and you won't be able to use it again. The mechanics for whether your succeed or not are not fully known. However, if say you try to cheat with the Seven of Hearts, and there is already a Seven of Hearts in play, you will definitely fail! You can swap a card out at any point during the hand.

Failing to swap
There doesn't seem to be any repurcussions for cheating and failing when playing with NPCs. I havent' tried cheating against another player yet.
