One thing u wanna realize when re-popping pf is y ur doing it, dont do it just cause u wanna "defend" ur blinds, do it because BTN or CO is opening a lot, folding to 3bets or c-bets or seems very spewy and therefore playing big pots with him can be advantageous. Hands like 99 r very tough to play oop in r/r pots without a good idea of ur villain's tendencies, the flop will almost always have 1 overcard and its gonna be tough to proceed if ur c-bet is called and u dont improve on turn. Hands like a4s r the same, they may fold out some better aces that BTN or CO is opening with but hell still have some strong aces in his range and therefore pretty much every flop is tricky to play with a4s oop unless u hit big or have a very good idea of how villain plays. The main thing IMO is not to 3bet for the sake of 3betting, 3bet enough so that ur range isnt predictable and that u can get some action from dominated hands but dont just defend ur blinds or raise CO from BTN with any pretty hand. As for playing back at light 3bettors i'd recommend calling much more liberally in position (910s, j10s, ajs, aq+, kq, 88+ etc.) ur calling range can become wider as ur knowledge of the player increases, when u call with hands like 65s its too often ur gonna flop a marginal piece and not know where ur at without concrete reads on villain's 3bet pot tendencies. Also realize that if villain is 3betting and auto c-betting than it is very profitable to take flops in position against him and just raise his c-bets with a very big part of ur range depending on the board. 4bet bluffing is also useful if u dont go overboard with it.
