River bet with A high

[obsidian]

MP here is 52/9/1.2 who seems to raise most aces but not many mid PPs. SB is 55/22/1.2 and cold calls way too much. Good river bet?

Maybe against just MP but not against both players. I think I'm c/f here. Maybe c/c depending on your read of MP and if the SB folds. You can't overcall of course.
