I'm a beginner so please someone correct me if I've made a few error's here. Generally let them do the betting for you, just check call your toppair + hands on safe boards and raise for value on the river. You may have to play a larger pot than you would like with 2nd pair hands, it would probably take some getting used to.You could probably increase and polarise your 4-bet range by bluffing with a few K3 type hands, also your 3-bet range if they are opening wide but you may face a jam a fair amount of the time depending on the player I guessCheck-raise the flop light when they c-bet occasionallytighten up your opening range from the button I think that's probaby a good place to start but I'm sure someone else can expand on this

Against 3bb open-raises - what you wanna play are hands which: a) are strong in general (TT, AK, etc. pp)b) can connect with the board and you can use your positional advantageFrom the very little info which you actually spread I would recommend you to set mine (hopeing to hit a set with 22 - 99) if deep enough and if he does CB a lot. Versus 3betting:- bet your strong hands and start limping other strong hands which can connect with the board (smal pp, suited connectors, etc. pp) If you need to tighten up or loseing up mainly depends on your current basic strategy. The question is: what do you wanna reach with a call / open raise / 3bet / 4bet whatever? You wish to have an overall improvement of your winnings. If you fold every Big Blind you have -1bb / hand every time you are in the BB. If calling/3betting with K3o increased this lose rather than reducing it there is no reason to do it.

Against 3bb raies you obv want to tighten up your defending range. this is becuase you are offered worse odds preflop to call and it becomes harder to play hands profitable. Against wide 3bettors depending how wide your PFR % is i would tighten it up a bit by removing some of the worst offsuit stuff.If villians 3b range is polarised  would create a 4b bluff range consisting of hands you can't flat the 3b with K6s as a example you do not need to 4b that big imo lets say he 3b 60-180 then 4b 180-400 will get him to fold all his bluffsif villians 3b range is primarely value idk off the top of my headi would not start limping vs 3bets unless we are 30bb> but idk how much experience on this subject.never limp small pp you are allowing him to see flops with so much junk that have good equity against our hand, i'd rather 4b over his jam depending on stacks and his frequency. against wide cbettors in 3b potsif hes cbetting most flops after 3b then you should be able to raise and make him fold a big part of his rangedepening how he plays turn you can consider floating the flop , eg. if he shuts down on must turns and c/f.
