99, what's next?

UTG+1 is LPA, plays 50% of hands and only raises when he is very strong. MP2 is SLPP almost TPP just limps when coming in, very predicatable post flop. MP3 is solid TAA 18/9/4 over 100 hands.

Seems like a straightforward raise, actually just plain old is.

What do you do here? Is it a raise to knock out the rest of the field? How aboout a smooth call and wait for the turn? I would like to think folding is not right at this point, but I have been way off before.
