$25nl - Rivered two pair against an iffy maniac

[jackatwork]

BB and I have a bit of a history. He started off the session by buying in for $5 and pushing every single hand. He did this until he lost $25 (20 of it to me in 4 consecutive hands). After this, he sat out a round, then bought in full and seems to be playing tight. He pushed one hadn preflop, everyone folded. We played a hand where we both flopped the same non-nut straight and he called down. Then this hand.
