Just checking up to make sure these are standard:

1) - Villain is running at 48/4/1

2) - Blocking bet on river goot?

3) - I figure I am priced in and still drawing live on the flop?

Hand #1 your raise preflop is way too small.

Hand #2 Once again the preflop raise is way too small, I would usually value bet the turn but c/c is fine too. If the turn checks through river is a clear value bet.

Hand #3 I'm not sure. I usually get this in on the flop though I think it's close, and calling might be better. I don't think folding the flop is an option and if I did call would c/f the turn like you.

I don't play these stakes so take my comments FWIW.

Hand 1:
To Doc: He is 3-betting the guy so I think a 3x raise is fine plus villain only has 65BB or so. As played I think value betting the flop and turn are standard but the river is kinda thin.

Hand 2:
I like the turn check here for exactly the reasons you said. The flop is so dry that he's pretty much always calling the turn with a Q and folding everything else. There's no real draws other than 76 which made it on the turn anyway.

Hand 3:
I play it the same, but probably jam it once in a blue moon....

Perhaps it comes down to style... I check most of my range on that turn and you bet most of your range, I can see both actions have merit however I prefer mine
