Total pot: t350

Here is my issue, if I make a standard raise to the donk bet it leaves me with 350 behind, which is not a very convincing turn bet, but could easily be called by villain on the turn if the turn doesn't complete his draw (or at least this was my guess). I can't just call here and give villain a free card. So what is the play?

what options besides moving in did you consider?

based on this post you are probably far too rigid in your bet sizing.

Shoving seems fine here. If the board was drier I could see flat calling and hoping he fires again on the turn, but I don't take the risk on such a drawy board.

The other option would be to minraise and get the rest of your chips in on the turn, I actually don't think it matters that much in this spot provided you don't fold or flat call.

After the donk bet on the flop by the villan, there is no more play left with your stack to pot ratio. It's fold (no way I'm ever folding here) or shove. Any normal size raise leaves any chips left behind in your stacks as meaningless. If you think he has nothing and will two barrel bluff then just call, but that is totally read dependant.

I was in no way thinking of flat calling there. I just couldn't make up my mind between a min raise, and get the rest in on the turn or to shove. I used quite a bit of time on this one, and thought that tptk probably pays me off to a shove, and a draw should fold this early to a shove, so I shoved it in happy to fold out the draw. He insta called my shove with a worse hand than I thought. After his cards got turned over I just laughed to myself and said thank you.
