19/6: AKo hand
PF: Ok - AK ahead of his likely range. SPR good for TPTK type hand.
Flop: Bet is too big. if he's folding, he's folding to a 1/2 PSB or smaller. $1 is fine. I'd read your hand to want a fold so as villain I wouldn't expect you to have a made overpair. If you do have an ovepair, what's the hurry in getting the money in? WA/WB should apply.
Turn: Spew. Which hand in your range completed? 87? Really? When he calls the big flop bet he's not going away. You are semi-bluffing yes (6 outs) but where is your fold equity?

19/6: AJo
PF: I normally steal smaller - SSNLHE suggests the bigger steal size if up against an opponent calling too much pre-flop. If he's fit-or-fold after the flop it's a bigger pot going down to cbets, if he's calling station post it's more streets of value from his second-best hands. No reads tho?
Flop: Fine. Good size considering flop texture.
Turn: Too small turn bet. I'd go for $2 or PSB. Your hand just lost a lot of relative hand strength, but the As makes a second barrel mandatory. If your opponent is not folding turn to a bet he is likely also calling a reasonable river bet - if you make the bigger bet the river bet can gracefully be an all-in when you hit your flush, or if you are thus inclined - if the J or A should hit and you think you're ahead (though I'd possibly check behind those hands also.) A big turn bet both maximises your fold equity from hands that beat you (two pair and set) and gives you best implied odds against hands that currently beat you (made flushes and sets) and gives you best value from hands that you beat (KsJx, other Ks hands)
River: Check behind is good. You're not getting value from worse and you're not folding out better. Not with this bet size at least. Even then I don't think a shove is better EV than a check behind. Folding to his small raise is also good.

19/6: TT
PF: Not comfortable. Happy to stack off against shortie. Not getting set odds. OOP. Do you think you can profitably steal?
Flop: Perfect flop - fully committed. Bet size good.
Turn: Good.

19/6: KQo
PF: Fine
Flop: cbet could be smaller. We are looking for calls from weaker and the flop is semi-dry. When min-raised I think I'll flat. Typically min-raise means this player will 99% of the time see a showdown. People generally don't expect to elicit folds when they min-raise. Ignoring the raise size, is he happy to get into a raise war on the flop with JT or a single pair? His solid range is pretty much sets and two pair. 5 combos of sets and 4 combos of KQ. 6 combos each of K2 and Q2 I don't really count as solid seeing as I normally don't put K2 or Q2 in preflop calling ranges. He might decide to spew with AK or AA, but why? Against a decent player I would tend to not commit on the flop but just flat. Once we raise and he shoves we do have to call though. A good player could have JT in his range and a bad player could have Q2. A range of KK/QQ/22/JT has enough equity that I'd prefer to flat and see a turn. I don't think I could profitably get all-in on the flop against that range. Against the wide range of a bad player that includes AK, K2 and Q2 getting the money in on the flop is probably best.

22/6: 98s
PF: Fine
Flop: Fine. Could maybe have raised smaller but not below $6. With his overbet he wants to get the money in in a hurry and it's always tricky to know how to bet to make sure he stays with his plan. I think the general obvious commitment raise here that "accidentally" leaves money behind is a good play. Especially good if the move is insta as it keeps his adrenaline up and prompts him to act quickly.

22/6: 87o
Fine.
