Hello jockel80,
Preflop: Why not 3bet here against his stealing range?
As played
Flop: I'd rather just let him continue with his CBets which has a lot of bluffs in his range while he could just fold them to our donk-bet. And yes, likely would as well Call the min-raise and reevaluate it on further streets.
As played if flop was donked
Turn: Guess if I called the flop then as well Calling the turn since it didn't change that much. Although I will keep my eye on his bet sizing on river.
River: And I guess I would just fold it here since I don't really see many hands what we beat, only reasonable hand is like some draw Tx although even with it I am not really sure if he is betting that big for value.
Best regards.
