VNMPOKER(5,1,m,n)

There are two players, you on the left, and the computer player on the right. Each player randomly gets a card from a 5-card deck containing 10, J, Q, K, and A. Each player looks at her card but doesn't know the opponent's card. Note that even the computer player cannot see your card! The initial bet is 2 Euros. The game is simultaneous, with the roles of Ann and Beth alternating between you and computer player. Ann starts by either checking or raising.

If Ann checks, both cards are revealed and the player with the higher ranked card wins the pot of 2m Euros. In case of a draw---both cards showing the same rank---the money is split equally.
If Ann raises, she increases her bet to n Euros. Then Beth has two options, she can either fold or call.
- If Beth folds, Ann gets Beth's initial bet of m Euros. Beth's card is not revealed in that case.
- If Beth calls, she also increases her bet to n Euros. Then both cards are revealed again, and the player with the higher ranked card wins the pot of 2n Euros. Again, in case of a draw the money is split equally.

To the left you can select the bet levels. To the right you can select your computer opponent. All of them play differently.
