Do I call this river raise? Villian was loose/passive.

[butters]

If he's truly loose/passive, his river raise means he can beat a pair of eights. I hate paying off bad players, so I think your fold is good.

[runa]

I probably prefer the line of bet the flop, bet the turn, check/call the river.

Why didn't you bet the flop? Were you trying for a check-raise?
