how's this hand played on the turn vs TAG reg?

i'd bet turn bigger like 80-90 and 3-barrel basically every river

bigger flop too

ok. and when he raises turn?

probably call (it's 186 total right, not 68+186?). his raise really looks FOS to me because what is he raising on turn that he'd flatcall on flop? but the problem with shoving is that almost every draw (+ a bunch of combos of pair+draws) has you beat, and it's quite possible he's not folding any of those.

could make an argument for jamming too though

jam over lol

nvm

Agree 100% with bigredhoss.

Since villain should never have a set or 2 pair here I'd probably lead shove all board-pairing rivers + non-diamond fives. Always shove when we hit as well. I'm too tired to count stacks but you seem to have enough behind that he can fold for instance A6hh on a river 8.
