Here is an example of a line that I have trouble with.
When my opponent made a pot-sized 3-bet I thought I had good enough pot odds to call but I decided to just ship it since I really don't like x/f-ing blank turns from an equity realization standpoint, especially at this stack depth.
Obviously in this hand I did manage to get there and make a flush but I'm not sure whether my all-in was a good decision. I'm only ever getting called by top pair and also some 2 pair and sets so it seems like I almost never have more than a 40% chance to win the hand. Also it seems to me given my (limited) experience the players in my pool aren't taking this line with bluffs and I'm really not likely to ever get folds with my 4-bet all in.
Could I have found a fold or a call? What are some heuristics I can use to help me make decisions in these spots? How does size of the effective stack change these decisions, if at all?
