Stars 1/2 - Several cbet hands - to cbet or not to cbet?

[JSampras1]

I think playing overcards is costing me a bunch of money. Here are a few hands. Maybe you could give me some advice on what i should do?

#1: Villain here is terrible, 53%VPIP 23%PF, 4.4 AF

Flop: (17.50 SB) 6[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">Hero bets</font>, MP1 folds, <font color="#CC3333">MP3 raises</font>, CO folds, Hero ??

I think i have to c-bet here. I seriously doubt this donk has the Jack. How should i respond to villain's raise? Assuming i call or raise, what should i do if i do not pair the turn?

#2:Here I have KQ instead of AK so i think there's much less chance i'm ahead. Villain is 27%VPIP 6.5%PF, 1.33 AF

Hero ???

Should i take 1 shot here? If called, should i just give it up, or keep betting?

#3: Here i'm in position, but i don't have oc's. I do have a straight draw+1 oc. I think i have to bet this right? If called, do i just check turn and cf, or what?

Again, assuming i don't hit the a or the k, do you think this is bet again, or c/f?


Hopefully this wasn't too long. Thanks a lot for your help!
