I am going to say 4-bet. If the pot has been raised, or if you raised it, and it's been 3-bet, then you have a solid bite. There is no need to continue dangling the hook. Focus on setting the hook on one player at a time. When you go fishing, you try to catch them one at a time, not all at once. I know you want to try to win a massive pot. But when you start letting too many players into the pot, that's when someone ends up getting lucky and you end up getting your aces cracked.
