Given reads, I don't see any obvious leak (under/over folding or under/over bluffing). The only thing I see is he may not have the under bluffing leak since you've at least seen a few bluffs from him. So in that case, I would just play it safe by using a balanced strategy where we don't under/over fold or under/over bluff.
So a balanced 3-bet range pre would be something like 40% very strong value, 60% bluffs. I don't think the limper really should affect us that much (our situation is slightly worse though since there's a tiny chance he limped AA-KK).
I'd 3-bet AA-QQ and AKs = 22 combos for value. Now for the bluff part, it's very important you carefully select ~33 bluff combos in a way that doesn't have you over bluffing by 3-betting way over 33 combos. I.e. if you have no combos memorized to use, you might end up just thinking "okay I'll 3-bet Ace rag suited, AJo, and some medium SCs as bluffs)" but this would be overbluffing.
I'd use something like AJo, A5s, A4s, A3s, 108s, 97s = 32 combos as bluffs.
Then on this flop, bet AA, KK, A
K
for value and A4s, A3s, AJo (with A
), 10
8
, 9
7
as a bluff. Then on this turn, bet AA and KK for value and bet A
K
, A4s, 10
8
, 9
7
as a bluff.
It looks like on the turn, you deviated from balanced to overbluffing, as AJo has almost no equity making it a bad bluff hand. This is fine to exploit V if he has a leak of overfolding, but by doing it you allow V to exploit you by either playing a balanced strategy or by underfolding.
I didn't see anything in the read that says V has an overfolding leak, so I think your line is bad.
