Villain has been playing pretty snug, not too out of line, and betting pretty small for value.

Hero?


I checked planning to check call the river, as I'd caught him bluffing the river a few times already when checked to.

The shove threw me off, as Villain has only shoved twice so far heads up, but at no point in the hand did i sense any real strength.

Advice on all streets greatly appreciated.
