FTP 55 NLTRN River Decision vs Berating Semi-tard

[ChicagoRy]

Villain has been berating me in chat all game. I played him once already and won on first hand with a gutshot, nut flush draw and A pair draw to his QQ on flop.

Reads: Villain has generally potted with pure bluffs on the turn when I check behind flops, so far when he checks on the turn in this situation I've seen him show up with top and 3-4th pair, don't recall which.

Don't remember blind level but I know we're about 25bb deep so I'll put stack sizes up accordingly (I know he had me covered and effective size was 25bb).

Hero (1250)

Villain (1750)

Blinds 25-50.

Hero on button raises to 100. Villain calls.

Villain calling light but prolly not enough to call him a station at this buyin.

Flop AK8 two suits.

Villain checks, I check.

Turn Tx (200)

Villain pots for 200, I call.

River 6x (600) Board is AKT86 two suits.

Villain shoves for what is 950 to me.

My questions

1) What, if any hand, do you take my line with on flop and turn.

2) What is the lightest hand you call with on river (regardless, not the lightest hand you'd check behind on flop and call river with).

I have a third question I'll ask after there's been some responses and I've revealed my hand.
