First, I like to bet a little bit more on the flop. I probably also lead the river for 1/2 pot and see what villain does. If you prefer to check, you have to be prepared to call. You're getting ~2:1 on your call, so I probably make the crying call. It certainly looks like villain has a 7, but I don't know why he pushes the river if he wants a call from you. I call this and expect to sometimes see 44, 88, 99, or a busted draw (like 34s), or something random like A5s.
