Spot 1:

3 handed 100bb stacks new to the table, I pot KhQh3dKd otb, SB calls BB calls pot is $21

3h4h2c flop we have KQ hearts

Check Check, should we c/bet here for a small amount of value and some protection at the risk of getting check raised?

Spot 2:

6 handed 100bb stacks new to the table, I open pot in the CO with AhQc9h8d button calls pot is $17

Kc5d7d flop

I c bet $12 into $17 with my low equity gut shot on the flush draw board, he calls, turn is an offsuit T

Should I bet this turn? I'm concerned that my fold equity is pretty small on this turn after he calls the flop but I'm also concerned that I'm going to be forced to fold my double gutter if he makes a decent sized turn bet. Perhaps I should be betting and prepared to barrel off on non diamond, blankish or board pairing rivers?
