(Please see the link above for the hands mentioned)

I was reviewing my game recently and was wondering about the following hands.
The situation is a single raised pot where we open on the button and the BB calls.
Let's assume it's a standard situation against an unknown villain, 100bb deep.

The question is whether we c-bet or check back.
Also, what do we do if we get check/raised?

What do you guys think about the following six hands?
I find arguments for both c-betting and checking for all of them.

Interesting quiz. Here my personal opinion for 2PLO and 5PLO

1) cbet 1/3-1/2 pot, block most of the hands, we'd like to get value from. Have to go really small to get them to pay with all their pocket pairs and longshot draws.
Raise: Make a decision based on timing and raisesize. General tendency: fold.

2) checkback. Board is too wet, V. isn't folding very often. Would hate to get x/r'ed with this and potentially fold a ton of equity.

3) cbet small. Protect hand against overcards, get value from worse pairs and longshot draws. Like 1) Decide on a raise, but usually fold. If the game was somehow tough, this would become a checkback for me.

4) bet/fold flop on the larger side like 75%+. Large bet both to get more value from all the worse hands and draws that find calls here, aswell as to maximize what little FE we have, prefer to end the hand on the flop.

5) I find this one to be hard. If bet, then have to bet large like 4) but don't want to do it, since we get called so much. Prefer checkback even though hand is too weak to do that. Probably should bet/fold. Curious what others think.

6) bet/fold medium to large size, want to maximize folds on both flop and turn. Hand is too weak to checkback and can't rep straights without betting flop.
