That looks like a decent fold. You're likely going to face a river bet as well, so it's really costing you a lot more than 4.75 to get to showdown. So when you call the turn, you're praying you're not drawing dead (if you're beat, you probably have an average of 0-2 outs), and that he won't bet the river. Also, you're going to have to fold up to 20% of rivers when a fourth spade drops and he bets again.
