Depends on a lot of things, like how you are perceived as a player, How you perceive the players you are up against, What position you are in at the table, Chip stack size's, The list can go on and on.
I once found myself in a game on the BB with pocket Kings 3 other players limped in, Now a friend who was watching me said "Boom shove it all in" I just said "No thanks, Just watch and Learn" The flop came K/J/J and I checked, the other players took over the action and after a series of bets and raises I just came along for the ride, After the 2nd King landed on the Turn I checked again, My Friend watching this on my computer could not believe I was playing so slow but after more bets and calls I Told him "These two are both playing 10/Jack" and he said "how can you possibly know that" I just said "I don't, but willing to bet you on it" The 4th limper folded on the Turn and then I started to raise, just enough so that the shortest stack would be pot committed and would have to shove all-in the other player just called and I re-raised again this time enough to make him go all-in and he did.
The cards were turned over and sure enough they both had Jack/10.
Now you could argue that any 4 of a kind can be beaten with a Straight Flush of Royal Flush, but with 4 different suits on the table when the Turn card landed that was impossible so Yes! I had the "Nuts"!
Give them enough Rope and they Will Hang themselves!
