Two Plus Two Newer Archives - 25/50 River Spot vs sweetluvin

Hmm with the PF action I am not in love with A8 anymore and even tho I have never played with Sweetluvin7 as you guys describe him he seems rather loose with his calling range so calling seems out of question if he is not overly tricky. I mean bluffing on that river seems suicide imho so we can discount bluffs a lot, shoving worse 2pairs for value is bad as well so it leaves us mainly with hands that have us beat thus raise/folding seems quite good. I like a big strong river raise (3,2-3,5k ish) and a fold afterwards. We discourage him from making a move, look very strong and have about 6k behind. I'm up for a 3k or smaller raise if he is not making moves at all but might fold out worse hands to a bigger raise, as I said I have zero history so I cannot give a too accurate analysis.
I don't see many suited connectors he would limp call UTG any clue if he could limp As6s, As3s, 52s, 57s? I mean if all those hands are in that range plus other 2pairs then I raise, if he only limp/calls with pocketpairs or higher suited connectors then I think raising the river is - even tho it might occure weird - spewy. Because there are only sets that will give us action (44, 66, 88). Imho we really need a good idea of his range to make a call > raise.
