Middle Set facing lots of aggression, huge 3 way pot

[maranello11]

Looks like a set of 88's may have got there or a set of 33's. When you re-raise though you need to make it like 120 or 150. This will give you a better idea of what you are dealing with. MP could have 2 pair as well, but I think 888 and the other may have 2 pair, tough spot weird hand. I like to lead sets in unraised pots, wtih boards like this.
