Villain in CO is 4tabling from Belarus. Only 11 hands on him.

I should have 3bet bigger (maybe to $0.22) given that we are so deep. I always miss this stuff when 4tabling zoom... His 4bet was very small and I felt that I'm getting too good of a price to fold. Looking back at it, I am not sure anymore. Would KJs make a good 5bet bluff? Should I ever 5bet bluff in this spot in 2NLz? Should I just fold now?

This is where I talk myself into floating out of position. My decision was heavily influenced by the fact that we are still pretty deep (SPR is still at ~4) and I'm blocking AK and AJ for value. I have a backdoor flush and backdoor broadway draw ourselves. Still, I should probably fold or raise? As played, I'm planning on bluffing a lot of rivers if turn goes x/x.

I pick up showdown value so my goal changes to try to check down and win vs random hands villain might show up with.

Since I have showdown value, I don't like betting out. Villain bets a little over half pot and I have a bluff catcher. We are blocking KK (which I feel might cbet flop even though it shouldn't). AA should not check turn ever and we are putting hands like AQ and AJ in horrible spots by shoving. I would play AK the same way for value.

Edit: Just to be clear, I never thought about calling his river bet.
