On the river (or 7th street in Stud), someone bets and another person calls, you have to have a very strong hand to make an overcall, or to be the second person to call the first person's bet. It's possible that the person who bet is bluffing, but he who called first cannot possibly be bluffing - he has to have something. " The first player bet straight into my nut flush on the river, and I had to choose between raising him, or to call him and hope for overcalls by the three players yet to act behind me."

An overcall is when someone is the second (or third or more) person to call a bet made by another player. We usually talk about overcalls on the river. It is said that a good player needs a stronger hand to call than to bet and should need an even stronger one to overcall. When you are second to act in a big field, you might just call with a very strong hand where raising might knock people out and calling might encourage overcalls.
