Should I go into c/f on the flop? Can I bet without committing myself?

I would just push PF and hope he thinks im stealing . That may devalue the hand somewhat but as you can see, you got a pretty good flop but dont have a good line because of the stack sizes. With a standard raise PF you put yourself in a position of hitting TP/TK or TP/2K to really be comfortable.

Im sure others would standard raise and then some would push, some would c/f, and some would donk lead and fold.

I think that's what sways it to a standard raise PF for me, it's very close though, 5-6BBs less and I think shoving would be better.

I'd probably shove small pairs with this stack though, beause they play even worse after the flop.

I don't like your flop shove at all, it seems to me like you couldn't work out what to do so you decided to shove yourself so you didn't have to deal with calling if he shoved over a normal sized bet.

I think betting your standard size and calling a shove or checking behind are both better than shovin for twice pot.

Yeah, I don't like the flop shove at all there. Pushing twice the pot just looks really weak, like you're trying to bully him off the pot with a mediocre hand. Is there something terribly wrong with a more standard CB there? You have 1375 behind on the flop, so you can make a bet of, say, 400 to try to take it down. That doesn't commit you to the pot.

Here's a thought: what about small-balling this? If he does have a good King he may very well be checking the flop to induce a CB, which opens you up to the check-raise. Check behind on the flop and you at least give yourself a chance to hit another Q, an Ace, or even pick up a backdoor nut flush draw. If he makes a bet on the turn, then you can decide what to do (assuming you're prepared to fold your unimproved hand here). If he checks again on the turn, you can feel more confident that your hand is good and bet out.
