should i bet my whole range here in flop with 45%pot?

not for 45, no

call riv i think

i have JJ to call river with...

how would you play flop?

the idea is you either bet most of your range small for 1/3p or so and 99 mby fits in there but meh
this is usually reserved for more static boards, where you have a range advantage
or you bet big with your best made hands and draws and c/f the rest of your range that misses

Thank you
So is either meh or x/f right? Mainly x/f?

What about c/f flop?

Oop in a 3bet pot you could x/f and be quite happy about it I guess, there are one million better hands to continue on QT2dd.

Check flop and evaluate. Need to defend 62% of our range otr. JJ is likely not enough. So unless you think hes massively underbluffing. River is a call.

Check(-fold) flop with this and 88. Also check(-call) some Tx and probably QJs. Bet anything else that has some kind of connection to the board, since it should be obvious what turn cards you'll be able to barrel with your draws and backdoors.
With 99 there are basically no turn cards you can barrel (as even if you bink the 2 outer, KJ gets there) so you should start with a check with this hand.
Just as some examples of hands in your range that have more robust equity, AK has 2 overs and a gutshot, AJs has 1 over and a gutter, KJs has an OESD, Axdd has FD, Axhh has BDNFD, A3hh has BDNFD+BD wheel draw etc etc. All those Broadway draws also block KQ/QJ/JT, which make it more likely villain has 88 or 76s or something. 99 is only crushing villain's folding range (underpairs). It's not doing well vs his calling range, and basically has no chance of getting to (and winning) at showdown if you start with a bet.
If it's in your range, you could bet 66, as it has a legit shot at folding out better hands (99-77), but villain never folds a better hand than 99 on that flop (and he doesn't fold any high equity hands either) so it doesn't make a whole lot of sense to bet it.

I would xf flop.

Is a cbet better on a T high or Q high board? I.e. T42 vs Q53? Or do we cbet both?

With 99? I'd check on both boards (especially Txx, where I'd go more polarized with a big bet), but the EV of betting should be OK, because it's harder for villain to have much (so you have more fold equity) and you're actually nearer the top of your range in terms of hand equity vs the continuance range. (e.g. AK has a ton of equity on QTx, but it's not doing so well if villain floats on Q53, whereas 99 plays badly as a bet on QTx, because villain usually has 2 overcards when he continues, but reasonably well as a bet on Qxx or Txx, because villain floats with 88-66,76s and folds most overcards).
