Hero: AK
Villain: Straightforward 1/2 black guy. Hasn't got out of line at all. Calls opens very weak. Plays straight forward post flop.

Hero raises to $15 UTG+1 and Button, SB, BB call.

Flop ($60): K3T
Checks to me, Hero bets $30. Folds around to BB who calls.

Turn ($120): 8
Villain takes the lead, bets $50 into me. Hero?

What are effective stacks?

Sorry, will include that now on. Hero $200. V $145 to start the hand

I think you just have to get eff. Stacks in here. He's only got about 55$ left. I'm never folding or calling here.

If there wasn't a flush draw I could get behind calling with intention of getting the rest in on the river.

I'm still trying to learn what donk betting means. He c/c flop and leads turn. I don't think he's doing that with spades or QJ. I think straightforward 1/2 players don't play their draws that way. They're usually on c/c mode OTF and OTT right?

Bet larger on the flop. As played I am going all in on turn. He's loose enough to have K-rag, could be setting a price for a draw, etc. Of course you could be beat but it isn't often enough imo, and a good portion of the hands that beat you would c/r flop on the draw heavy board.

When you have a strong hand on this kind of board you have to bet flops big. At least 2/3 pot IMO. As played with the stack sizes just stick in. We don't block any of his draws and we're never folding to the price on the river. Although, I might be able to see an argument for calling and folding any spade river.

$45 OTF so he has $85 behind then GII on the turn right? And if he jam raises flop I call it off?

Yes, that's what I'd do. If he ships flop we snap it off. Tons draws and worse hands he could do this with.

Bet a little more on the flop -- it's so draw-heavy make them pay.

Turn is a shove with these stack sizes.

You need to know the player to figure out what the donk bet means, but at these stack sizes on such a drawy board, you can't fold top/top here, and calling is a mistake. He could have picked up a pair or straight draw to go w/ his flush draw. Who knows?

However, if your read is that he is only betting with hands that beat you, go ahead and fold, but never show Sometimes going with your read/gut is OK, even so short -- I just couldn't fold here.

Bet more on the flop and make it easier to jam the turn.

In general it means they have a weak hand and want to "see where they're at". If you raise then they comfortably fold having bought their information. Sometimes it's also a feeble attempt to take control of the hand. I'd say thats the case in this scenario with the added draws on the turn. He probably has something like J9, picked up some equity and thinks he should just do the betting now. Donkbets are almost always nonsensical and should be treated and such. If you have a made hand on a wet board then raise for value. If you have a made on hand on a dry board then just call and let him barrel off into you.

I try and watch for odd play from players at this level. Often there is no rhyme or reason for why a bet takes place. I feel like a lot of 1/2 players only lead with a made hand but you have to figure out from watching a player whether this is the case. If I see a guy making a bunch of dumb moves I tend to give less and less credit to why they do what they do. So without any prior knowledge I'd raise 'em all in on the turn. You are paying for this information. If you lose to a set or two pair then think about all the other actions(tells) that took place that may help you get tipped off next time what they are doing. Reload and use the information you just paid for.

I jammed over him on the turn and he had K3s. Donk betting is so strong from straight forward 1/2 players. But its nice to know he called my $15 open with that hand.
