Reads: <font color="blue">Villain is 35/15 over about 200 hands and is typical retard. Flop call is somewhat iffy, but I think he's FOS and plan to be able to take it away later a lot. Plus, I have a couple backdoor draws and I'm getting a good price. I decided to check the turn when I hit the nuts. Can I raise the river for value?</font>
