I mean I'm really trying to figure it out, and I get stumped every time. I though SB had 9x, 2 pair, a set or an overpair for sure.
when MP just calls on the turn he has to be either still on a draw or a scared pair of something. When he raises the river I'm pretty sure he made it, because what could he have called with on the turn. the old bottom-pair-no-kicker I did not expect.
