I play on Ignition without a HUD, and the Hand History Replayer doesn't seem to save all your hands, so I just remember that the starting stacks are all 95-100bb. It's a rainbow runout, suits of flop weren't relevant since I checked back.

BTN: 100 BB
SB: 100 BB
BB: 100 BB
CO: 100 BB
MP: 100 BB
Hero (UTG): 100 BB

SB posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.5 BB) Hero has AJ

Hero raises 2 BB, fold, fold, fold, SB calls, BB folds

Flop: (5 BB, 2 players) T 9 5
SB checks, Hero checks

Turn: (5 BB, 2 players): Q
SB bets 5 bb, Hero calls

River: (15 BB, 2 players) J
SB checks, Hero bets 10bb

Having the ace of diamonds makes this a poor cbet combo and SB flat has a lot of pocket pairs, T9s, 99, maybe AQo on the conservative side, suited broadways JTs-ATs, suited Ax.

SB takes the betting lead on the turn, and I call with the OESD, I can have AQ/KQ/AK/AJ/KJ so the queen does hit my calling range from SB's perspective.

River is a J so sb checks. I'd bet here around 2/3rds pot with AK, I still have some KJ combos that didn't have good removal vs ATs/KTs/JTs that didn't cbet flop and didn't raise turn. (I don't think I'd raise here with KJ since he's drawing dead most of the time, and his full house draws will only have 4 outs except for 99.)

I decided to turn second pair into a bluff as I actually don't think J gives me enough showdown value as SB can still have various two pair combos, QJ or even AQ that's not comfortable 3betting preflop.

It's hard to have a bluff here since everything is a straight or Q or a J when I get to river. I'm checking my AQ/Qx and taking showdown, so I need to turn pairs into a bluff.

If I have 16 AK and say 6 KJ combos, and 9 AJ combos, for 2/3rds pot that's roughly 2.5:1 value to bluffs and I think AJ makes sense as my bluff.

I only beat a KTs/ATs that decided to lead turn if I check river, and he still has those various 2 pairs that I can get to fold if I bet.

It looks like a reasonable line. I'm unsure about the sizing on the river. If the size is big enough to get him off the hands you mentioned often enough, then it's fine.

I think without the jack might need to bet bigger. But with a J, I don't have to bet polarized as he's less likely to have hit JTs which might bet turn reasonably and x/c river, and he's more likely to have the bottom of his 2 pairs/naked Qx. I don't block QJs which should always be bluffcatching vs. this sizing but it's hard to get to the river with perfect removal.

I think this is fine. I’m always overbetting river though, if we can have 16 combos of nut hands and Villain can never have these hands, always Overbet.

I’d be very surprised if a Solver didn’t agree with this.

I x river expecting to win at showdown pretty often. Maybe you can bet 1/3 pot to get called by 9x and Tx

I think river is a bluff but you probably shouldn't overbet that often as only AK can overbet for value. Kx should bet about what op did.
