This is probably the weirdest river card to hit. If I lead out here, and he has AQ or AJ, or even 77 and decides to raise me on the river, I will have one of the hardest decisions to make on the river, as I will probably have to play this hand for my stack. I have maybe 214$ left in my remaining stack.
What do you do here, and why?
