THE SHORT VERSION

How to play

One card each. A $1 ante. The higher card wins.

01

Get your card.

You each ante $1 and draw a different card from a single suit deck. You and the computer alternate who acts first.

13 ranks. No ties.
02

Make your move.

The opener checks or bets $1. The other player checks, bets, calls, or folds as appropriate. When facing a $1 bet, call $1 or fold.

A good bluff has its place.
03

Let the card talk.

At showdown, the higher card wins. Win or lose $1 after checks, or $2 after a called bet. Folding costs your $1 ante.

All amounts are practice money.

BEFORE THE NEXT HAND

Questions

Is this real money?

No. Every dollar here is practice money. There are no deposits, purchases, payouts, or betting accounts.

Which cards are in the deck?

There are 13 spades: 2 through 10, jack, queen, king, and ace. Ace is highest. You and the computer always receive different ranks, so a hand can never tie.

What happens when I check?

Checking adds $0 to your ante. If you act first, the computer can check for a showdown or bet $1. If it bets, call or fold. If the computer checks first and you also check, the hand goes straight to showdown.

How much can I win or lose?

Your net result is $1 when both players check or one player folds, and $2 when a $1 bet is called. Winning a $4 pot therefore adds $2 to your net winnings, because $2 of the pot was yours.

Why can a lower card win?

The higher card wins only at showdown, when neither player folds. If you fold, you lose your $1 ante even if your card is higher. If the computer folds, you win its $1 ante even if your card is lower. Each history row labels the ending as You folded, Computer folded, or Showdown.

When is the computer’s card revealed?

The computer’s card is revealed after every completed hand, even when someone folds. During betting it stays hidden. Its betting decisions use only its own card, your action, and the strategy probabilities.

Is the game balanced?

The deal gives each player the same chance of a higher card, and the computer does not use your hidden card to choose its bets. Acting second has a small strategic advantage, so the opener alternates after every completed hand. Over each pair of hands, both players get each position once. With equally strong play, this balances the positional advantage; luck and your decisions still affect results. See the original game analysis.
