What you will learn

Translate a betting action into the incremental chips committed at a decision.

What the actions mean

Fold gives up your claim to the pot. Check passes the action without adding chips when you face no outstanding bet. Bet opens the wagering on a round. Call matches the outstanding amount. Raise increases the amount others must match.

A player facing a bet cannot simply check. They may fold, call or make a legal raise, subject to stack size and betting rules. Posting blinds creates forced bets before the first voluntary action. A full treatment of all-in, minimum-raise and side-pot rules is beyond these introductory exercises; simplified examples state what amounts are legal.

A total is not an extra amount

“Raise to 60” means your total contribution on this betting round becomes 60. “Raise by 40” refers to an increase over the previous total, and can mean something different. Always identify what is already committed on this round.

Earlier contributions are not paid a second time. If you already have 20 in on the current round and face a total of 60, calling requires another 40. At the start of a later street the round totals reset, although the previously contributed chips stay in the pot.

Worked example

You posted a 10-chip big blind. Another player legally raises to 30. How much more must you put in to call, assuming nobody else changes the price?

Your current-round contribution is 10.
Matching 30 requires a round total of 30.
Subtract 30 − 10 = 20 additional chips.

Calling costs 20 more. The total 30 is not a new 30-chip payment.

Common mistakes

Checking when an unmatched bet is outstanding.
Reading “raise to” as “add this amount again.”
Subtracting a previous street’s contribution from the current call price.

Keep these ideas

Name the legal action in the stated situation.
Compute incremental costs from current-round totals.
Distinguish round contributions from the pot accumulated across streets.
