$16 stacking off vs a poor lag early

[vers]

Hey. Only a few stats on villain but he's extremely active early on and I think I'm ahead 100% of the time here. I figure he has a pair +fd or just a pair and is trying to get me off my hand. I rarely get all in in a spot like this early, but against this opponent it seemed alright.
