The Deal

Both players ante. The deal alternates each hand. Each player receives three cards over three rounds, with a betting street after each.

Non-dealer acts first on every street.

The Three Streets
The Shallows one card, face-down
Each player is dealt one card face-down. Look at it. Bet.
The Current one card, face-up
Each player is dealt one card face-up. Both players see both. Bet.
The Deep one card, face-down
Each player is dealt one final card face-down. Look at it. Bet.
The Reckoning

Reveal all cards. Sum your three.

Highest total wins the pot.
The Fool is wild. The holder declares its value — anywhere from 0 to 21 — after seeing the opponent's full hand.
Tied hands — each player draws one card from the deck. Higher card takes the pot. If those tie, the pot carries to the next hand.
Betting

Standard action on each street: check, bet, call, raise, or fold. No limit on raises.

Position The dealer acts last on every street. The deal alternates. In a long session, the edge belongs to whoever reads better — not whoever holds the button.

You know your two hidden cards and their one showing. They know the same about you. The entire game lives in that gap — what the face-up card promises, what the face-down cards conceal, and whether the bets between tell the truth.
