I've been the more aggro player. I lost a bit looking him up a couple times light on the river in spots where I induce bluffs from the usual aggro bunch. Won it back with aggression, then lost a smallish pot a couple hands ago to put us here.

He's been folding the flop a lot and I think he has a piece here almost always. Is this a spot to save chips or are we committed?
