bad river for top 2

[kapilalink]

Opp is VERY passive post flop and playing way too tight (although he is raising every button and calling loose from bb). This is literally maybe the 4th time I have seen him double barrel in like an hour. What is best line on river?

Wow how gay.

I either c/f or shove, leaning towards c/f.

I still shove, bad players aren't folding AA or KK here or a worse two pair
