Home game question: how many times can you reraise?

[Boobie Lover]

The only time you cannot reraise in NL is if you don't have any money left to bet, or if there is a shortstack that reraised but is less than the original bet (so if you are playing .5/1 and you raise to 3 and a shortstack moves all-in for 4, you as the initial bettor cannot reraise any more even if other players call the bet).

In limit, the house decides how many bets you can put in. Online, the cap is usually set at 4, but there is no rule against having no cap.
