AAA facing river strengh

[xd40]

He's a fish, no stats on him. I joined recently the table and have been playing laggish and have 3bet somewhat frequently.
I took 100bbs off him recently.

not sure what to do on the river, as his pot bet means a ton of strengh most of the time, but he was fishy playing a ton of hands and i have been agressive but ..
