Riverplay

[Sushiglutton]

Been checking my stats and have noticed that my aggression on the river is much less than on the other streets (F: 2.9, T: 3.2, <font color="red"> R: 1.8</font>, Total pf: 2.7 in about 9k hands). Is this normal or is my riverplay too passive?

Also, I remember from SSH'em that u should sometimes raise the river with a marginal hand to shut out overcallers. I have never found a good spot for this. How often does a situation like that occur? (Guess this could have something to do with the first part).
