In limit play minimum and maximum bets are defined before you enter the game. For the first two rounds the minimum bet applies, and for the last two rounds you must bet the maximum (which is usually double the minimum). It doesn't matter what happened in the previous round.

So, let me see if I'm understanding this right.

A game would go like this...

- Small blind 5
- Big blind 10.
- First action bets 10.
- call fold call etc...
- Flop comes.
- Check check check...
- BET happens. Bet MUST be 10 or more.
- Call call call...
- Turn comes.
- Check check...
- BET happens. Bet MUST be 20 or more because the limit is raised because this is the third round.
- Everyone calls.
- River appears, hands are evaluated, someone wins the pot.

Wait a sec, that's only three rounds. Is there a betting round after the river? I so rarely see rivers on the TV show, I'm not sure. By the time it gets to the river, someone's usually gone all in and the cards are turned up in anticipation of the river.

Anyway, what I'm asking is if there's a difference if that red "call" above was a raise to 20, does that make the red 10 there have to be 20 or is it reset to 10?
