Revision as of 04:14, 31 January 2012
This is a two player version of Go Fish with a 9 card deal out where the human player always goes first. It is assumed that everyone will know what cards are booked out and what cards are fished. The computer acts as arbitrator so there is no way to lie, cheat, or steal.
Also, this program uses a simplified deck (no suits but four of each card) similar to some children's specialty decks.
The computer strategy relies on the following facts and public knowledge which are kept for each player in the player's public field. Public is a table by rank. A value of -1 indicates unknown state, any other value is the known number of cards.
- a. Public counts can be adjusted when a player makes a book.
- b. If the opponent asks for a card an unknown can be changed to a 1 as they have at least one card of this rank.
- c. When one or more cards are surrendered during fishing , the public counts of both players can be adjusted accordingly.
- d. A card drawn requires that counts of 0 be set to unknown unless the cards were booked out.
Strategy:
- (i) Request any known cases of 3 of a kind first.
- (ii) Request from other known cards second. The request should be in proportion to what you do not hold in your hand. That is if you have 1 J, you should have 3 chances of requesting it.
- (iii) Guess. This should also be in inverse proportion to what you hold in your hand.
