What do you think about this hand guys ? I play online poker for a couple of months and i keep having a hard time in these spots . Is this a fold on the turn ?
Stacks:
UTG - UTG ($2.13)
MP - MP ($3.07)
CO - CO ($2.12)
BTN - BTN ($2.05)
SB - Hero ($1.98)
BB - BB ($2.85)

Preflop: ($0.03, 6 players) Hero is SB with Ks Js
UTG raises to $0.05, 1 fold, CO calls $0.05, 1 fold, Hero raises to $0.20, 1 fold, UTG calls $0.15, CO calls $0.15

Flop: Th 2d Jd ($0.62, 3 players - Hero: $1.78, UTG: $1.93, CO: $1.92)
Hero bets $0.20, 1 fold, CO calls $0.20

Turn: 7c ($1.02, 2 players - Hero: $1.58, CO: $1.72)
Hero bets $0.65, CO raises to $1.72 (all-in), Hero calls $0.93 (all-in), Uncalled bet of $0.14 returned to CO

- really, really hate 3bing pre out of position with easily dominated hands
- really, really hate betting so small on the flop when deciding to continue that allows so many drawing hands to correctly call
- by the time he jams on you on the turn you're too far in, there's enough in the pot that i think you have to call

Yup I agree with you . So it s a fold against 2 players in the pot raise against cutoff and call vs utg ?

I'd usually fold KJs in the SB when it's UTG+CO in the pot. I'd squeeze vs CO+BTN, and sometimes overcall.
Most of your squeezes in the situation detailed, where the initial raiser has a tight range, should be TT+, AK, and Axs (You can even just fold AQo if you think UTG is nitty). Kx hands aren't really beating anything that calls the 3-bet, and it's much more important to have an ace for blocking and post-flop equity.

C-bet is fine, but I'd often check the turn and then call, to give villain a chance to bluff his missed diamonds and KQ, and so that you don't get shoved on and be left in this horrible spot. 98s, JTs and 22 are all decent possibilities for villain, but I guess you're priced in to call in case he has a (combo)-draw.

you re right but i dont think that 22 calls this large 3bet ? i dont think it s profitable what are yourh thoughts on this ?

CO is getting >3:1 to close the action and play the hand in position. I wouldn't expect him to fold 22 here.

I don't think 22 should be calling the initial raise, or the squeeze, but people really like set-mining.

Just fold pre. With reads, a slightly -EV hand might become a slightly +EV hand. But you don't provide any reads so I assume you don't have any.

Mostly X/c flop. AP definitely check turn.
You probably keep having an hard time on these spots beacuse you're betting too often decent combos with SDV that cannot improve much on many runouts.

Cbetting bigger would be a mistake.
We're OOP in a MW 3BP vs two fairly strong ranges on a dynamic board with a combo that can hardly improve on most runouts (if not already well behind vs overpairs/AJ/sets), bloating the pot won't be good.

Would it be a bigger mistake than OP's bet sizing?
