Yah, but he had a diamond in his range there like someone who cb shoves Q93r has QQ in his range. It makes no sense because he doesn't need to protect against anything and he doesn't need to bet nearly as much to set up a river shove. I would be more likely to fold the turn if he bets 1/2 pot or something gay like that. I still don't think it's absolutely terrible. Even if I only get his stack when I make 2 pair, it's only about -10bb ish in EV. As soon as I can weight his range to non-flush overpairs it becomes +EV.
