Villain seem like a decent reg not that many hands vs him but from what I have seen he plays pretty standard (about 250).
on flop he could have any thing so I get value on a lot of his hands
when he barrels this size normally I have seen him playing strong hands so I put him mostly on AT+, A4 A7
On river I tried the Pleno shove, hoping to rep hitting my backdoor FD and mostly a hand like KhJh, KhQh and shove 145bb into a 37bb pot
