This is deep stages in a PKO, so bounties are relevant.

This player I had tagged as a maniac player who would throw out random bluffs when checked to. I had a note where on a similar 4 flush board vs another player, he snap bet 1/2 pot as a bluff. In this case he snap bet pot on the river, which is why I ended up folding thinking it was more for value. Thoughts on how I couldve played leading up to river as well?

your call preflop is obvious due to pot odds.
You hit a very well flop and maybe this moment you have the best hand
but with 3 other players involded this "better hand" will easily become lost hand.
I would try a bet of 5bb since i Play first to test the waters.
If someone raise me i would fold.
The turn is a disaster completes a str and flush-

I can see why you posted this OP.

I read through the hand history and was thinking, ok you call it off here and we talk about whether V has enough high heart hands to warrant the call.

Th has the same value as 2h and we’re facing a polarised range. I certainly would not hate the call given reads and the high % of air this player has in range.

Reading back through the HH now, would you prefer to crf turn, cc turn or cf turn?

I'd fold preflop. Think it's going to play too poorly 4way.

Probably folding turn as well.

Just because someone has bluffs on 4 flush boards in a spot, it's a bit of a stretch to think they're just half potting turn into 3 uncapped ranges and continuing to pot river with a ton of bluffs, but who knows.

Do you have HH of the earlier bluff villain made that you referred to in OP?

I dont but this was a good ol fashion maniac player. Not a passive fish, or a good player, he was a maniac player so thats why its so close to me. If this was any competant player, I would definitely play it different

^ folding Preflop is really bad /nitty
