I agree with what Renton said.

Hand 1 I'd only fire if I was ready to fire a lot of turn/rivers, and rep an overpair/strong hand.

Hand 2 is a type of board where we can never really just fire two barrels, since villains range is a ton of pair+insiders/draws that will call down to the river almost always. I prefer a ck back and peel turn and re-eval river line.
