I suppose I could 3-bet a little bigger because we're 150 deep. This is my standard sizing.

Since I'm not super experienced in deep stacked play (weird because I'm way better post-flop than pre-flop), I tend to not adjust my c-bet sizing.
In 100BB spots, I usually go 50% - 50% - 75% jam

So bet 30 here?

I think he usually raises 89s if he does call that, so his range should look like 88/99/JTs, QTs, QQ/JJ/TT/, AK, 8x, 9x.

This is where it gets tricky. I tend to get way too paranoid in these spots and forget how strong my hand is.
JT and QQ got there, but I should still have the best pretty often.
Combine that with the fact that I have slightly more Qx in my range, I think this is a bet, right?

So b/x > c/c > c/r ??

And now he jams.
Still losing to the same hands.

I didn't think about it during the hand, but he could definitely turn a hand like TT into a bluff, which I for some reason always get mid-hand.

I'll say that I folded in-game, but I'm not sure. He could value jam AQ here or turn some pairs into bluffs, but I lose to a bunch of hands too.
After my turn check, KK is also near the top of my range, so folding would be exploitable, right?

Thoughts?
