#1 Just raise/get it in on this flop ldo. Board is too wet to get fancy. As played get in on this lovely bricked turn when he has just commited himself with just about anything. As played I fold river I guess.

#2 With some reads on him postflop Id just iso pre. You can add a lot of JXss to this guys range, why Id probably fold the turn.

#3 I just complete pre. Usually Im talking myself into a call on this river, given that only J9 got there and his sizing on turn and river makes little sense. Guy is probably peeling flop with any 7, T, QJ, 98 and some gutters. River is basically a brick and weird players love to bluff paired boards for whatever reason. You have to be right only 33%, so dont muck.
