hand 1:
I check behind because I hate getting c/red and don't expect villain to bluff lots of rivers. I don't expect villain to think he has a lot of FE, so I don't call that much rivers.
I do wonder how good a river raise is when the flush completes and villain bets.
Hand 2:
I check behind and call non A/K rivers. Though I don't really now how good that is.
