Lets have a look at his range: Im curious if u agree with some of my assumptions

What can he check on turn:
TT/JJ/QQ/KK = 24 combos (i think he should fold +- 20 combos of this on river?)
A3s/A4s = 6 combos (i dont think he has all low suited aces) so lets say 3 combos of this.) (he will have a hard time to call river with it)
A5s = 2 combos
Higher Ax Ak Aq AJs = 27 combos ( question is how many of this he will check on the turn, would like to know what theory is saying,) If i have to make a guess: theory puts half of it lets say 14 combos in check range. But i think in pool i can put less in his X range, because pool is probably not checking strong enough. lets say he keeps 8 combos of the stronger Ax in range.

I can have some sets, and some twopairs. Problem could be that i have not so many strong Ax. Good thing could be i dont have so many bluffs, so he can call less. So do u think i can bluff 99.
