Very basic question here

Yeh that's right. Just think of the BB as the initial bet, so you either have to call, or raise it by at least as much, or fold.

If the BB is $xx and first agressor raises to $40 and you re-raise him another $40, then the next person to act has to put in $80.

Hey magictroll, very basic question lol. I thought this was easy but I have a headache now reading the answers. If you go with your assessment you wont go far wrong:

"Ok I think I get it. The minimum raise in any round is always either the BB or the last raise amount that round. In the next round, it resets back to the BB, right?"
