I hate the river shove too. Leaving aside everything else though, re:
I think K9s is a mile ahead of this guys l/c range, and even if it wasn't, he's likely just going to pay to see a flop then fit-or-fold it anyway, so I'd be making this $1.50 with probably about the top 25% of hands, maybe even wider with reads, then cbetting very liberally but quite small, like half pot.
