I bet this. I'm not really expecting to take this down, but if someone raises this then I know I can get a checkraise in on the big streets if I hit my flush. If the flop action goes check-check-bet-call-call and the turn is a spade then I'm almost forced to lead it because I can't count on the TAG to bet the turn after he got 2 callers on the flop.

I suppose the side benefit to betting the flop is that you will take it down sometimes, although I think it's pretty rare because the TAG is usually raising this PF with broadway cards and will always call this flop with a gutshot. Even the loose player probably has a decent holding (like broadways) when he limps from UTG.
