I'd just call actually.. first reason is that he minraises the river, tilts his hand range towards the ones that beat us. I'd expect to see a two pair boat up on the river more than a set boating up because he didn't bet the turn, but who knows, might be caution cuz of the 3 straight or a weirdish slowplay or whatever.

Second most important reason, if I read stack sizes properly that'd be quite an overshove of an extra $100.. if effective stack sizes were smaller I'd be more inclined to push, now it just seems due to the large amount of $ left to shove it'd tilt his calling range towards the range that beats us again..
