2nd barrel on river vs HU 3bettor

[sc000t]

Villian is pcfic_pkr or something like that on stars. Hes a regular small stakes HU PLO player, pretty tight, doesn't put on a ton of moves but is solid. Rarely see him getting his money in as a big dog unless its cooler. I think villian respects my play, he's seen me play a lot of HU PLO and knows im not an idiot, he knows im pretty aggro post flop.

I expect him to lead out here with most hands and or draws. After he checks twice on flop/turn I was thinking he completely missed with some slow connector, double paired JJTT maybe or a weak <font color="black"> </font> <font color="black"> </font> QQxx/AAxx.

Does anyone fire again on river? If so, how much?
