No Bovada HH until tomorrow. 6-max, Heads up pot, 100 bb stacks and villain is 58/19. Fish raises in MP 3bbs, Hero OTB 3bets 9 bbs, all folds and fish calls.

Flop: 7h 2c 2s He checks and we check back.

Turn: 3h Fish bets $6 > $9.xx and we flat.

River: As Villain full pots $19.75>$19.75. Hero????

Is the play to call or raise here? I would think that we can get some value if we shove, but with his pot bet I feel like it's 77, A3/K3s/34s etc. or 22 A LOT. I think he definitely calls a ship with AQ/AJ but I'm not sure he would full pot it when my hand looks like exactly what I have.
