Villian looks like a reg, I want to have a polarized 3bet range and this hand seems like a good canditate for that.
On the Flop I think I have a sufficient mix of Pot Equity and Foldequity to cbet, since QJ is not in my 3bettingrange, I will only have 87s as an OESD, so cbetting Gutshots seems a good idea for balance.
The turn brings an overcard which allows me to put pressure on many hands such as AT,88 etc. I also think there will be a lot of river cards to continue bluffing, like Spades for example.
On the river I thought this to be a good bluffing spot, since its hard for him to have a K here often and I think he will fold everything else
are we double barreling with AK here? I think KK is more likely to double barrel. if we double barrel AK and an A or K hits river we will often be paying off a value bet to villain. and when we are best well be finding folds from villain a lot. seems like J is only card that helps and well be playing for a split some of the time. we have very few bluffs to work in when the river blanks to triple barrel.
I would've said the same as some of these previous posters, I'd say your range is value-oriented compared to his. To be more specific, I'd say KK more than AK as it's monotone and you can't rep the flush obviously.
But as mentioned, certainly AQ,QQ amongst others are credible for you as broadways (ultimately leading to 2pair or better on these runouts) are good for you and only mildly good for a part of his range.
