I disagree with a lot of your post.


3rd situation. You say that you think you will get someone to fold to your 3-bet when the pot is reraised? I don't think you are going to get BOTH of your opponents to fold here. I fold here.

4th situation:
What is your opponents 3-betting range? How deep are the stacks? This is really vague advice. If we are assuming deep stacks then I would give this guy a 3-betting range of TT+/AK. What exactly are you a favorite of? Also, presumably you are OOP most of the time in this spot.

6th situation:
Too vague again. What happened to the other limpers? Anytime you get 3-bet with AK you aren't liking life. You are probably going to have to hit to win and when you do you won't win much. Sometimes when you hit you will end up losing more money to a set(AA/KK). This is reverse implied odds.
