Rules and guidance
Check passes action without adding chips when no bet is owed. Call matches the amount required to stay in the hand; fold gives up your claim to the current pot.
A raise increases the current bet. The minimum legal raise and any pot-limit or fixed-limit cap are shown in the table controls.
All-in commits your remaining eligible stack. You cannot win more from any opponent than the amount you matched; extra wagers form separate side pots.
