Hand 1: I probably c/f the river. I think he has a two pair or flush here a lot and will rarely have a T that missed a draw. I also think just a weak pair is not in his range much on river.

Hand 2: Gross. Umm he's not aggressive so this is tough. I'd probably c/r flop and maybe fold if he pushes. As played I may fold but that is probably nitty.
