I'm just posting everything, including results, for i'd like to judgje both his and my play.
My play:
- Cbet overpair;
- Big barrel on the turn to get flushdrawers to fold this hand.
- Check behind on river seemed sound 
His play:
If I had toppair king kicker, 1 overcard and 2ndnutflushdraw in that spot, i'd either donkbet or check-raise. I'd especially not play the line he played and neither call such a turnbet.
If he check raise's the flop - he's committing a lot of chips; if he check raises to say..300/350 - pot is going to be like 700. You Turn bet is most likely going to be 600, and imo, im shipping the turn after check raising the flop? If you line of thought is "i'm ahead on the flop" the turn hasn't changed matters.
I Dunno ?! Weird Hand, i guess u lost the minimum which is always a good thing - his play stinks, too weak/passive

Why do you want flush drawers to fold their hand?
Pretty standard play, I would bet 80 pre anyway. Blinds are low and villans will easily call for 80, if they do for 60.
Cbet is ok, but 2nd barrel could be a little bit weaker, like 200, check behind river is fine

Because I don't want to give him the odds to chase his flush and then see a diamont on the river.
Why wouldn't you want them to fold Olorion?
Probably just because he has 18% chance to hit his flush draw on the river, what mean we will take down the pot in 82% of sitations. And by betting the pot on turn he will be more likely to fold and all you will get is 330 chips.
Preflop I make it 80 as well in this blindlevel, just for value and because they are never folding to 20 more chips anyway. 
Flop is a standard continuation bet, and after his call I usually barrel on the turn here as well.
We can assume that we are good here almost every time, and if we get raised on the turn it's usually not a float and I am able to muck my hand at that point against reasonable players.
And you usually don't want flushdraws to get out of the hand, but just let them pay too much to chase their draws so that they are making a mistake by calling.
On the river the flush arrives, and I prefer to check behind here all the time, because I don't want to run into a check/raise (as planned here) and I don't see much value in a bet, because villian alomst never calls a single pair of jacks on that river card.
As for the opponent, I donk this kind of flop and try to get it in as soon as possible with my ~1mio. outs

You're not going broke with an overpair?

What if you barrel the turn and the rivercard completes the flush and villain donks all-in? Then you have to fold and stay cripled with 500-800 chips...Is it worth that gamble?

It depends.
If I know villian and assume he plays reasonable, I can fold to a turn check/raise because this almost never will be just a single pair of Jacks.
Good players will most likely play top pair for potcontrol in that situation early in a DoN.
Against donkeys, who go broke here with top pair any kicker or any kind of draw, I always stack off here of course.

Yes, it's definitely worth in my opinion.
The flushdraw only arrives in about 1/5 times - That means 4 out of 5 times we extracted maximum value and can even catch river bluff bets with the busted flushdraw for more value.
And if the flush hits on the river and we get pushed it's an easy fold where we still save some chips left and just got sucked out.
Few things:
0. As you should know, chips you have are far more valuable than the ones you may acquire in Double or Nothings. That's why you don't want draws to stick in hand, so betting large is good as it forces the draws out of hand.
1. Raise PF 80.
2. On flop or turn, go broke against bad player/unknowns, fold against reg if he raises you. Regs calling range there is pretty much PP's only, so you don't even have to bet turn if he calls the flop, in this case I'd bet the turn too because the flop shouldn't hit your range very well so he may very well call 2 streets with medium pp.
