I think you hit on exactly the issue in hand #1 which is confusing the fact that he could possibly raise with two pair with the likliehood he raised with two pair. I also hadn't really thought about things in terms of risking two to win one, but in those terms it makes me feel better about hand two. The reason I was self critical on hand #2 is probably a little revisionist history because after playing a while longer I realized that the Villan in hand #2 was far more likely to raise an over-valued hand than the Villan in hand #1, so if I was going to three-bet anyone on the river it should have been the villan in hand #2. In reality though, it's still risking two to gain one, so it seems bet/call is good.
