AKs is pretty cards, but with a solid read on Villain this is a tricky spot. The real question is, can you find a better one? How often had the players to your left been defending their blinds? Had you generally gotten away with stealing? Have pushes from short stacks been called liberally at the table so far? If it's a tough table to steal from, I might go ahead and stick it in there now, hoping for the best. But I think it's a marginal spot, so if you're confident you'll have other opportunities AND you are very confident in your read, I think you can let it go.
