bet because you will get people folding if they missed, haven't got a spade, and also you may well have the best hand. I don't think you want to give a free card with 2 spades on the board. If you get raised I think you can fold it easily enough as your kicker is mediocre. Can't see 55 or 67 check-raising here. And if they were, you have to call down all the way which really isn't worth it.
