In this type of poker game, there is a minimum bet equal to the big blind but there is no limit to the maximum. You may bet all your money at any time.
The minimum amount for a raise must be at least equal to the previous bet or raise in the same round.
For example:
If the first poker player to act bets €10 then the next poker player may raise with a minimum of €10 (total bet of €20). There is no maximum limit. However, if you don’t have enough chips to call a bet, you may bet with all that you have ('all-in'). In this case, you can only win the portion of the pot covered by your chips.
