Trying to get in more checkraises on the river, both with strong hands and as a bluff. Here I thought that stack sizes were right, and the river is a good bluffing card. Does he fold enough here to make it worth it? Villain is fairly straightforward, hasn't done anything unusual. We both start with a full stack.

I get 99 in the BB, villain open raises from MP. SB calls, I call.

Flop: [7c][5s]. Checked to villain, who bets 1/2 pot. SB folds. I call?

Turn: (Pot=$42): . Check, villain bets $25, I call. (Thought of a checkraise here, but decided not to (comments welcome).

River (Pot=$92): . Check, villain bets $25 again, I checkraise allin for $140 more.
I think his range is pretty much JJ-AA. Spew or worth it?

Absolute Spew-age.

Check raise the turn if you wanna feel him out - but check-call, check-call, check-raise all-in when you think the guy has a big overpair? Don't do that again.

I don't like it, you didn't help any draw, the only threat you have here is backdoor flush, and no one believes in them. So IMO you win here only if you have the best hand anyway, all better hands will call. I even think that TT will call often.
