Pushing people off hands with big draws is nice, but you don't always have to do it. There is no reason to put your stack into the middle on a flop like this, especially with stacks this deep. You can easily just call his flop bet getting 3-1, because if he flat calls your raise and a blank hits, or your hand improves but is still second best then you are in for some trouble.

Getting your entire stack in after being 3-bet is probably not a great idea. At most you are 50-50.

Usually a raise of this half pot bet is going to get you the pot, but this "monster" draw is still a draw. Why risk it?
