NL100: Did i lose alot of value here?

Sorry for posting this in shorthanded. but wth, its poker.

Villain has played 4 hands, posted out of the blinds. Not fullstack.

Thats what i know about him

In the heat of the moment i felt like villain was feeling pot committed here and would play atc to showdown, should i have used my position here?

He had about 33$left

i mean, he had 32 in and 34 back so your reasoning seems fine and its suprising he folded. that said, i would probably relax and let the money go in on his accord since i have position and a massive equity advantage vs almost all worse hands in his range.
