Top pair river pot lead by manton

Ok so this guy ws playing 87/8 over about 150 hands. Standard raise and c bet. Think i can make my turn bet bigger to like 7/7.50. River lead looked so bluffy from 89,j9,kj etc. Hadn't seen him pull stuff like this before, first time i'd seen him be aggressive really but he ho. Is this a standard call?

Villain has possibly the fishiest name ive ever seen. Its got everything - luck, a name, a number and capitals.

Even this cunt has a lot of nut hands on this river to be fair. That said, theres a fair few gutshot kinda hands that hes gonna have too. Without reads, i probably fold, but its pretty close. When he pots it, i think his range is def weighted towards strength. Bleh, its a pretty nasty spot, i wouldnt hate a call.

You're right about the turn bet. The flop bet is fine, esp 3way, if it was HU, id full pot it and pot the turn. As played, 2.5 on the flop = $8.60 on the turn, bet $8 and then shove 33.79-8-2.5-1.2 = $22.09 into $24.60 on most rivers.
