Thoughts:
Villains: This is basically the first orbit of the blinds and so I have no reads on either villain.

Preflop: I raise 4BB (standard) two calls. Their ranges could be pretty wide, plenty of fish down at NL2 calling raises with a whole variety of hands. If they are any good they might have a pair or a suited connector here often or maybe some broadway combo.

Flop: The flop is middle cards and drawy so I am on guard but I have to bet to get value and to protect. When he raises I am pretty unsure what action to take; Fold seems weak, Call allows him to see the turn and there are a lot of cards I don't want to see there, Raise puts me in jeopardy if he already has me beat.

What is the "Standard" line here? Infact any general advice with dealing with flop raises is appreciated. I am quite poor at evaluating them.

I'd just fold here. He's raising the flop 3-way, and even if he has a draw, its not like you're ahead. If you had some stats that he was nuts, I suppose we could proceed, but in this spot, kings aren't so good.

But then again, after running some stuff on poker stove, I don't think shoving is that bad either. But then again, the range I've given villain here may be a little wide:

Hand 0: 56.427% { KcKd }
Hand 1: 43.573% { JJ-44, AcJc, AcTc, Ac9c, Ac4c, Ac3c, Ac2c, KcJc, KcTc, Kc9c, QcJc, JcTc, Jc9c, Tc9c, 97s+, 86s+, 75s+, 65s, 54s }

Out of position, I would shove it. Can’t just call it and if you reraised, you’re pot committed anyhow. I’ve had guys reraise me all in with bottom pair thinking I only have two overcards AK/AQ. You might be up against a set but it’s a chance I am willing to take. It’s likely not a made straight. Two pairs is unlikely. If he called ya with 79 or 56 then give the luckbox credit and get him next time. He might be reraising ya in that spot with 88 or 10 10 type hands.

I think that all in is good here
