tbh getting to the river with a pair of 9s and calling for the rest of your stack seems spewy.
unless he's somehow works up the courage to donk lead jam ahx, i can't see the donk being a bluff.

Furthermore, you have TT (rarely),55 ah2h-ah5h sometimes (if you split your flushes), ATh, sometimes ah6h-ah9h 9xTh, occasional 7xsuited. I would lay down this 9T combo.

Also really thinking about it, 89 is better to call then 9T as his 7 hands probably contain an 8.

i am not really sure what your turn sizing is trying to accomplish...
on the river i think given population tendencies this is rarely a bluff.
it would also be helpful to have a heart in our hand, even though i am aware that we do not get there with that many offsuit heart combos.

please leave the results out next time :)

I don't see good enough reasons to make the call on the river. We can't exclude all overpairs/flushes and 7x makes a lot of sense for villain to have.

I would need an aggro read to make this call. Againts a normal reg it seems like a clear fold to me, based on how normal regs tend to play poker.
