a raise from the button isn't going to thin the field.

This is an interesting point.

This is certainly table dependent but I find if you just call, sb will complete ~80% of the time and bb will usually check without a strong multiway hand. If you raise, SB will call 10-20% of the time and BB will call ~60% of the time.

So I think a raise can often increase your pot equity and the times you don't hit you will have a free look at the turn fairly often (or a flop bet can give you a free look at the river). A preflop raise can also save you from the disaster of a reverse dominating hand like J4 or J5 in one of the blinds. Finally there are 2 limpers from MP which makes me think we are usually way ahead of them and they may even be the ones dominated or drawing slim. If there was an EP limper I would probably change to a call here.

However, given the read on the SB here I think a call is fine.
