Same villain in both hands. Aside from myself (hohoho) this is one of the better players I have come across on Cake. He seems very competent and I think a standard line here is gonna tip him off that I've got a huge hand so I try playing a little different. Lemme know what you guys think.

Hand 1:

$0.25/$0.5 No Limit Holdem
6 players
Converted at

Stacks:
UTG ($50.00)
UTG+1 ($73.95)
CO ($38.85)
Hero ($68.19)
SB ($22.18)
BB ($70.20)

Pre-flop: ($0.75, 6 players) Hero is BTN [Ad]
UTG raises to $2, 2 folds, Hero raises to $6.5, 2 folds, UTG calls $4.5

Flop: [9d][As] ($13.75, 2 players)
UTG checks, Hero checks

Turn: ($13.75, 2 players)
UTG bets $9, Hero raises to $28

Hand 2. I have seen him pot control a lot of turns and also give up when he whiffs so I think a bet here might make him scared.

$0.25/$0.5 No Limit Holdem
5 players
Converted at

Stacks:
UTG ($50.95)
Hero ($101.95)
BTN ($89.90)
SB ($32.60)
BB ($64.30)

Pre-flop: ($0.75, 5 players) Hero is CO [5h]
UTG raises to $2, Hero calls $2, 1 fold, SB calls $1.75, 1 fold

Flop: [Qd][5s] ($6.5, 3 players)
SB checks, UTG bets $5, Hero calls $5, SB folds

Turn: ($16.5, 2 players)
UTG checks, Hero checks

River: ($16.5, 2 players)
UTG bets $9, Hero goes all-in $94.95

Hand 2: I agree that betting the turn is best.

Hand 1: If he is decent like you say, he saw you 3 bet preflop so unless you've been doing this a lot recently he will probably put you on something decent. And then he bets the turn when a K falls. So it seems like he must have some kind of hand because he doesn't seem to care that this board is good for yout range. He also raised UTG which again means he probably has something. I think there is a decent chance he has a very good hand like 99 or AK. I think he would 4 bet with KK. Given that he has a hand I would expect him to fire the river so I would just call on the turn. He has like $34 left and the pot will be $31.75. If he makes any resonable bet he pot commits himself. Honestly it probably doesn't matter and you are getting his stack anyway if he has something and if he has QQ-TT or AJ he is folding to your raise here (or check/folding the river if you just call).

Hand 1 is going to be pretty hard to get action on anyway you play, unless you cooler the guy. But I tend to bet these flops since I CB almost always here with my other 3-betting hands.

Hand 2, betting the turn is mandatory since this looks like a total float. You'll get played back at alot, especially if you float regs alot, which you probably should be doing. I like this type of line more if you hand wasn't soo strong, much better when you are trying to squeeze value with strong 1 pair like hands rather than boats. Not overbet shoving but raising the river.
