I figure this was a good move since i have two over and straight draw if he doesn't have a king and lots of fold equity

im folding pre here. You dont have too many hands on him, also depends what his read is on you. If your nitty and you think hes just trying to blind steal here with trash then i could see a shove here but you'd need some prior dynamic for that.

Spewy. And you don't have two over. (Even if he doesn't have a K). You only have two over the bottom flop card, a gutshot, not much showdown value, and all of your dang chips in the pot. All you beat here is a bluff, or you're hoping the LAG will fold.

Don't mind call pre here, though I probably just fold.

Flop is awful, it's a fairly dry board and Kx smashes his range

He's risking 225 to win potentially 225. So if you fold half the time or more preflop he's making money.

This is a tricky situation, since only about 1/5 of your hands are good to shove if you know he's going to call 100%. So just playing push/fold strategy here doesn't necessarily cut it (again unless you think he's folding a good percentage of the time).

I'm considering overshoving or calling here preflop. Most likely he has a hand in his shoving range, wants to get you to call preflop and then fold the flop when you miss. He doesn't necessarily have anything on the flop but they doesn't necessarily mean you can just call him either since you are probably behind his range. I'm actually folding to the probe bet on the flop as played - but maybe I am wrong.

Also, I'm assuming .5,.3,.2 payout structure.

Since no one's responded yet - out of curiousity, did he fold or call - and with what?

Normally, I would say just fold preflop but sometimes people actually do fold to the allins. They are minraising often because they don't want to risk their entire stack. I'm not sure what percentage he would have to fold to make this positive EV.

For instance, a garbagy sort of hand like 78 suited might be shoving here - but he might be probing you to see if you make the allin. I'm not saying this a good play or anything but it might be profitable to some players. Then again fold is always safe and probably correct.
