This looks about reasonable to me, more or less. With a different read, I'd go one more bet on 6th or 7th. If, for instance, by "pro" you mean someone who is playing WAY below their level, I wouldn't worry about one more bet here. And yes, the fact that 3rd was a possible steal situation should make you lean towards the more aggressive course here.

Not raising 3rd would be really terrible IMHO. You shouldn't limp in that situation ever, especially in a high-ante game like this one. Your opponents will become very suspicious if you do. IF the limit was a little lower I'd buy an argument that these players may be used to people who are too loose passive, but 8/16 is right about at the point where players will all be aggressive ENOUGH that calling looks too weird here. Add to that the insane equity edge that you are giving up extra action on, and the raise is super clear.
