Hand 1 - Pretty standard, I would still bet a little less at the turn. Something between 3/5 - 2/3 of the pot would do the trick. Would go broke on the diamond river for sure.
Hand 2 - Would bet here so we can get as big bet as possible on the river. Most of the river cards you hit will get you paid on the river also, and he might even donk bet - call when the spade hits. The river is std, I don't know how you even got words "really bad calling station" and "3rd bullet" into the same sentence
