Big Limpin'

When you're playing multiplayer poker and get late in a no limit multiplayer poker game that's a tournament, you should basically never just call before the flop (which is called limping). Either raise or fold. The reason is that the stacks will be small compared to the blinds, so limping and then folding to a raise costs you a significant portion of your stack.

Good players will realize that you're limping too much, and they'll start giving very difficult decisions that you don't want to make. Tournament play rewards survival, and limping means that there's no chance you're going to win the pot without seeing a flop.
