On both hands I think I am good 90% of the time vs the sizing and I should be raising. First hand was hoping for a brick river because BB is a bit of a calling station with top pair type hand. I am pretty sure SB has 2 pair+ here, some flushes, but would expect larger sizing. I get in my own head of keeping other weaker players in the pot and end up missing out on a lot of value instead of just trying to get stacks in because I don't have many bluffs against this player or on this texture as field caller. What sizing would you use on both hands?
