1/2 Is river shove suicide? Calling/folding seem bad

[RiverFenix]

Villain is unknown but seems to be on the looser side.

Getting sick odds on a call but my kicker clearly isnt playing if hes donk/calling w/ AXcc. Cant really figure an unknown for much else.

You won't get him to fold an ace in my experience. I call.

I just call. He led weak and called you twice already and still leads out weak on the river. Anyone playing such an odd line can show up with a lot, missed draws, 2 pair, sets or a straight aswell as Ax.
It looks like a calling stations line with a hand he doesn't know what to do with... and I don't bluff calling stations.
