some random thoughts:
-u certainly dont have to defend dominated hands like A9s vs nits, i personally much prefer 3betting with such hands ip, but play very tight oop, coz the guessing game just sucks ---> folding pf imo the best vs this opp with such hand
-as played pf, playability is the best as u played when he r u, ure certainly crushed by his range, he mostly wants value from lower pp vs him strong QQ+ here, but: 1, u dont have to bet so much, betting 1/2pot esp vs tight plrs does the same job, they dont raise bluffs here and just call pps, and mostly their draws too, coz they are mostly afraid.
-u can opt for diff lines coz of the former: we know we are b/f here; and folding tptk sucks, +more: opp is presumably weak tight so he wont 3barell ntg like close to never, so we can play c/c and reevaluate turn, since he often times goes for pot control and we can still spike some 9 or A which might be good for massive valuetown play at river
/depending on his ability for thin vbets either c/r or bet big ourselves if he cannot, but expects us to be wanting him to fold more.. which his wts prolly suggests too/ .. if he bets turn again then on most cards /usually overcards to 9 except for A i am folding coz he is scared himself with lower pp and doesnt wanna get c/r on turn so his bet would in overwhelmin majority mean he has it, on river than we can b/f mostly if checked on turn, but again, we dont have to be betting big, coz these plrs just dont bluff in these 3bet pots very often /unless u have some read confirming the opposite/
