You are getting odds to call but you're also losing equity for every player in the hand. Multiway I think I just let this go after the check-raise. I don't know what the buy-in was here, but a check-raise is usually very strong, especially into multiple people.

We're hoping to hit a flush here, that's our best outcome. But the way UTG is playing it might not even be good. Now, that's not likely but it's absolutely possible.

Multiway pots are hard to play, and even harder OOP.

Of course it's easy for me to say all this after the fact. In the moment it's harder to find that fold. The pot is big and it's just a few more chips every time there's an action. So you decide to throw in the extra... a few chips here, a few chips there.

Before you know it you've put in a third of your stack on a draw.

I do it all the time.

You hit a Q, but like the flush it may not be good either. And then the non-diamond A on the river. Ouch.

So what happened?

i expect the Q to not be good very often and yeah, its not a great situation after the check raise. MW is very hard to play i agree. i think it was like 97cc for UTG and maybe a set for the other player.

This board is very good for your range, as you have alot more straights and 2Ps than the other players. Vs a smaller sizing from MP you could consider x/r although 4 way you probably want to stick to Ahi and Khi FDs with at least a bit of backup EQ or some huge combodraw like 97dd.
Vs the big size and the further action you played it well, you have too much EQ to fold at any point in the hand, It obv sucks as you will be up vs a higher FD some of the time, but still with the odds you are getting and this being a lowstakes MTT I would def go with it.
