h1 is a weird line for a bluff, I think unless he's been getting out of line we can quietly fold the river vs a raise, feels like a slow played jack to me. I'd b/f turn, b/f river. Had I checked turn, I'd c/c river rather than leading.

h2, we have the button HU, raise or fold. I'd raise a king. Flop misses a huge amount of his range, so after raising pre I'd bet flop. Had I limped, I guess I'm not so interested in the hand and am happy to check down, or fold to any bet.
