SB checks, Hero?

I think his river checks pretty much says he's holding a jack and wouldn't like to play such a big pot cause I think two pair/set+ would be betting at least half the pot here. I very much would like to value bet the river but the pot's already huge and I don't want to play for my stack with just an overpair. Any value in doing so?

Sure looks like he has a J.. I'd prolly shove.

id check this behind against a tag and shove against a donkey

push is good against a 50/17
