Deep 5/10 vs. Donk

[-zero-]

The BB has taggish stats, but he is a ridiculously terrible player. I've seen him get it in several times in horrible spots with bad hands. The SB is a 70/5/.5 after 100 hands. I've seen him play two big hands, one he got it in on the turn with the nuts, the other he min-raise bluffed the river with A-high. I'm really at a loss with what to do on the river. Thanks in advance for any help.
