Call
In poker, there are three ways to respond to a bet: raise, fold, or simply match it – this is called a call. Imagine someone places a certain amount into the pot. With a call, you signal: “Okay, I’ll pay exactly that amount, but I won’t raise.”
Why do players do this? Perhaps because you have a fairly good hand and want to see what happens next. Or maybe because you don’t quite have the courage to raise the bet. In any case, it keeps you in the game – without much risk, but also without putting any pressure on others.
