Free card or winning UI on a turn semibluff? Can't have it both ways. If you are raising for a free card, then do it. But don't expect to win UI with this hand. In other words, you can't bet again on the turn if the spade doesn't come. If the other players caught any piece of the flop, middle or low pair, you are getting called. You will not win this unimproved 95% of the time at .5/1 or 1/2. Thus, your raise for a free card would have been a waste of a bet. Especially if they are even half aware of the free play for flush draw concept. Call flop, call turn = 1.5 BB
raise flop, semibluff turn = 2 BB (and as I see it, no better chance for winning). Again, if you had any overcard, then I say easy raise.
