AI for card games

I'm looking for documentation regarding A.I. applied to card games such as
bridge,hearts and, in particular, whist.
Can anyone suggest me some good site on the web?

These are the rules of Whist:
52 cards deck
4 players

in the first round the mace-bearer gives 1 card to each player and turn
another one as a trump.
in the second round the number of cards are 2 each, the third round 3 and so
on till the 12th round with 12 cards each.
then 4 rounds with 13 cards each are played. In this rounds there is no
trump.
then you start going back: one round with 12 cards, one with 11... till the
last round with 1 card.
Before the round begins,each player, starting from the one next to the
mace-bearer, has to declare how many hands he thinks he'll win.
if the player takes exactly the hands he declared, he scores 10 points plus
the hands he declared, otherwise he gets only 1 point for each hand he took.
Ace is the highest card.
the player who begins can play every card he wants, and the other players
have to play a card of the same suit, if they have one. Otherwise they can
play another card (likely a trump).
The highest card on the table wins, unless there is one or more trumps: in
that case the highest trump wins.
Who wins the hand starts to play the next one.
That's all.
Obviously, who has the highest score at the end of the 28 rounds wins the
game.



I play this game with my friends but I'm trying to create a software for
playing against the computer.
Any help is welcome
