I agree with others, that you should raise, and fold to a push/committing raise. If you make it $80, and he pushes you'll have an EV of -$4:60/hand if you call (given that everyone else folds) (pot will be $569 and you'll have to call $397 w/ 40% equity). Also, given that you are correct in your read that he would only do this with a set.
