ATs UTG1 hits straight vs flush draw

dont donk the turn and the river .. Yes turn and river is a bit too spewy for my taste.

second dont post spoilers. and dont post the results especially in the headline. results are not important.

So call down from the turn after the raise from CO ?

Apologies for headline, but I thought it was descriptive of the issue - didn't think it gave away the result. And I posted the spoiler as I thought it was relevant to my reasoning about pairs - I'll not do that in future.

Calling the Flop is just fine. You have a decent draw but A and K are tainted outs especially multiway so you're probably drawing to 4-5 Outs clean outs and SB definitely has some hand he's willing to continue if raised and better keep it multiway and charge more from everybody if you hit and draw cheaply => call Flop is fine!

I don't mind donking the Turn multiway as CO might be scared now and checks back the Turn with a hand like KQ or Q9 Q8 etc. And once he raised the Turn again i would just call down as he could easily have raised the flop for a freecard and even for value with a naked flushdraw and frequently he does have something along to his flushdraw. A2 or K9 with 1Overcard or a Gutshot and an Overcard.

Since CO is unknown i wouldnt mind reraising the Turn but your Hand looks quite like AK or a flush yourself so i'd guess he's got a flush himself too often so => calling Turn and calling the River. I don'T understand why you donked again on the River where you should have reraised the Turn as UTG and SB seemed to be still drawing and now on the River they fold all their draws. no value to gain from those draws. And if you consider yourself to be ahead on the Turn you should reraise but your line is really inconsequent and what you'll force by the donk is that just his better hands are probably gonna raise and worse hands like 2pairs just call but would bet if you'd check so either checkraise the River or check/call.
