Top Pair in a STEP 5

[Jman28]

I'm trying my hardest to find some hands for you guys to look at. It's tough to know which of your plays are questionable.

This is from a STEP 5.

The Villain has only raised a couple times preflop thus far, and I haven't seen his hands then.

He only called when a short stack went all in ~400 with AA, I suppose hoping to get callers behind him. That entered into my mind during this hand...
