in hand 1 I think I lead the turn.

Villain could have a hand like AK with a spade, KJ with a spade, KQ, or TT at the bottom of his range. He just called your flop raise, which means he doesn't think he can beat the field UI. It also means that his raise was for protection and that he would have much prefered to get HU. This rules out QQ, JJ and maybe AA from the top end of his range.

By checking the turn, we're forcing him to bet all of his paired hands - including the ones that we beat like KQ, AJ, and TT.

If we lead and he raises we can make an easy fold. More likely he'll just call and we could get HU, where we can check and call on the river. If we lead and don't get HU, then we check and call one but don't overcall.

hand 2 I think I like.
