It was relativ late in the tournament, but not yet ITM.
Chip average was in this time 13000, I was not so desperate that I had to shove my chips here.
I Flopped Top Two Pairs, Nut Flush Draw, Gutshot Straight Draw, 3rd Low Hand and I decided to try in this spot to build a big stack and try to win the tournament.
In retrospect I think the hand was maybe overplayed.

I'd be thankful for your opinions.

Looks fine

Looking at it some more, even though I don't think hero can fold by the turn, a smaller sizing on the flop is probably better, especially if it lets you re-open if shortstack jams

Thanks for your answer.
yes a smaller raise and a reraise all in on the flop would have been probably better.

CO had 6 8 3 2
Bottom Two and a marginal low hand

BTN had 3 4 9 J
Nut Low Hand and hits runner runner straight

but also with that checkraise all In on the flop I would lose the Pot anyway...
can't imagine the BTN folding the nut low hand in that spot even if I go all In.

I don't think your hand has lots of incentive to bet the flop, and betting so big is imo a clear mistake. After that you should just shovel the moneys in though.

Start with a check, if BTN bets or calls a bet, just call, otherwise shove.
