The problem with this question like many others of its kind is that the situation is too general. Okay I agree with four players behind as a standard play it is a resounding NO. But I would prefer to see a little more information - is in a cash game or a tourney, what is the profile on the initial person in the pot, what are the four players behind you like, what are their relative stacks, etc. If you call, you are providing every player behind you with delicious pot
odds to call and hit lucky, if you raise - depending on the type of players behind you the callers/re-raisers will usually have better
hands than your and off course the original player into the pot may have a hand. So it doesn't look good. But say you are in a tourney close to the bubble, - the first person limps in , you are getting short stacked but have enough to damage any callers - a shove might be in order. But say you are the big stack - no danger of going out, and have four tight players behind you, you may decide to call, take a flop and if you hit, play it to showdown so you show everyone you are playing "loose" when actually you are just playing the players.
