I think this is a call but I'm curious what you guys think.

The only draw that got there on the turn is some kind of silly gutshot or a 78...

He could definately have a spade draw or picked up a diamond draw with a suited king, but most of the time I think he has top pair or two pair. Oh and also 55 I guess.

Wat do?
