On the first hand - don't you have tons of fold equity if you push since you've been so tight? Or is BB not that aware? Or are you certain that the overbet means a made flush because you've seen him do something similar?

Second hand - I think after the limp/raise you have to play set or get.

99 hand - I think you can call with crazy pot odds. I guess it depends on your reads though, so you were probably right.
