He probably views our range as high flush draws, 9 with 3 high cards/backdoors or kk.  If he is a thinking player he probably realises we have few sets in our range.

He can definitely have 99 or JJ in this spot.  He folds most JJ combos to your flop bet with the SB behind however.  If he has j9 in this spot I would think he would jam more than 50 percent of the time.  If he opens 40% from cut off he is slightly more likely to have j9 then a set. There are a bunch of other hands he might raise with.  Such as a J or a 9 + A or K FD some str8 + pair combos.

I give villain a much wider raising range as I think from his perspective he perceives he has a lot of fold equity with his turn raise considering how deep we are.  Its way too exploitable to fold this spot I don't see how we can get away from getting it in.

Against opponents who play ultra-tight we can obviously fold my assumption is the average zoom 100 player is not like this (perhaps the wrong assumption).  

I think your average zoom reg calls our jam with aa,ak a decent portion of the time in this spot (I could be wrong about this)

I think the key to the decision comes down to how often he bets a single K on the turn and how often he shuts down with two pair+ on river.

I think raising or calling flop is fine.  

I don't like raising the turn at all.  I think most regs rarely fold sets, he doesn't call all 44s prefop and we block qq so not many combos vs KT. By not raising turn villian might also pay off a river brick with a aj type hand.

River is tough getting 3-1.  Only plausible value hand we beat is aj which he likely checks.  We block clubs if he has k clubs he could have a straight.  I think I pass as well.

I think I would jam turn.

My rationale is that the 9 looks pretty safe from his perspective and there is a decent chance villian thinks he can push you off a lot of marginal draws.

I think most people continue betting aa in this spot and potentially a good portion of their ak hands.  Combo wise he is about equally likely to have AA as he is to have kk or k9.  There are also a large number of ak combos in his range plus he may bet the nut flush draw twice as well.

My thinking for what its worth (might not be worth that much)

I am not sure that betting the turn is standard.  My inclination would be to check more often than not.  A bet doesn't get called by many worse hands and we don't need to protect our hand against much, it would appear to be a reasonable hand to put in our check calling range.

I think the river is a pretty clear cut call.  Getting 2.7 - 1.  There aren't many full house combos he can have.  We block TT (he might raise the turn) and K4 (not a huge number of those hands he calls with preflop).  I think he could easily be value betting a lower flush or choose to turn KQJ or similar into a bluff.
