CO and blinds are tightish solid players, the bigstack on the button is seeing a lot of flops playing passively postflop and getting lucky.

Is this a good spot to stick in a raise seeing as almost any raise would almost leave you pot commited and the likelyhood the button will call ?

If-so just a standard 3-4BB raise or a push ?

Wasn't too sure what to do with this hand.
