Value betted myself to death here lol

This is what happens to me when my mental state is "sucker villain is going down with his Ace! Muahahha f#ck it, lets recuperate all those BBs i just lost on some random cooler". Its does happens some times.

However that shove OTR seems over the top to me.

Btw the villain must been thinking if u had a better flush or not, before calling otr

x/c, x/c, x/c is my preferred line with a plan to bluff catch and also keep Villain's value bet range wide.

Yeah just x/c dude there is a flush possible you know. Stop thinking they are capped when they aren't and try to value too thin. They are not (all) so stupid as to cap themselves on a moment's notice. And don't forget it's one of microstakes gimmick that they don't (re)raise enough. Any street. Any hand type.

x/c, x/c & exploitatively donk/fold OTR;
x/c, x/x, Probe big/fold OTR (although raising shouldn't really occur too much on this runnout so you might bluffcatch, but people don't have the guts to bluff raise your probe enough for it to be a good bluff catch.
No way I'm going broke so deep with this hand on this texture.

He even tanked to call with a flush, which should be an indication of how bad this line becomes for you value really fast. Is it even a value bet if he tanks his flushes? What worse will call?

Well i guess up to turn the hand i played well.
But as the others mentionend out, you have got to think about which worse hand will villain call here?
With the river shove you turn your hand into a bluff.
On the river best is check fold, or bet really, really small and fold against a raise....

But that is not easy to realize while playing....

check call the turn and check call non club rivers , villain can also see the flush so it's unlikely villain is betting 3 streets with worse than a flush , they might possibly barrel off sets vs a checking line for 3 streets. I would fold preflop also as I think it's a slightly loose defend vs a 22/17 over a decent sample size for those stats.
