Looks pretty good sofar and sounds as if you were making the correct adjustments vs this guy for the most part. How much was he folding to 3-bets. If I have an opponent who's folding shiotloads you obv wanna be very bluff heavy with some strong hands to balance, but obv being polarized. You can even flat AA KK QQ etc sometimes if he folds shitloads to 3-bets and you have a somewhat aggressvie image for c/r flops etc. c/r overpairs HU canbe super profitable vs guys who hate to fold to c/rs.
