River Jh (pot $148)

Hero ??? I called.

What do you guys see his range being here? Thinking about it further, bottom is set of 2's and 6's... I guess he never raises any ace. Never bluffs because there's not much fold equity to be had. 3-4 is top and what he has most of the time. Any input on how it was played?

Will update results.
