Preflop
I lean towards a fold here. You are basically trying to setmine, and you are facing a very large 6X open from someone, who only started with 73BB, so he dont really have enough left behind to give you the implied odds, you need. The limper has you covered, which is good, but we can not be sure, he is always coming along.
Flop
Hit the set. Sweet. Bummer that nobody bet, but then you just have to build the pot yourself. As someone already set, go a little larger here. Maybe 500 into the 820 pot, not just 320.
Turn
Flush got there, and now the fish donk lead into us. He is saying, he has a flush, so per definition your hand is now a bluff catcher and a draw, and it makes no sense raising. You obviously can not fold either, so only option left is to call.
River
You brick, and now the fish overbet the pot and put you all in. Lovely spot! Sure he could be bluffing or overplaying two pair, but I am not sure, this is a profitable call in the long run against the population in a 1,1$ MTT. So without a very specific read I probably fold this.
