1) I'd check the flop with a set for sure. Only the flush draw could possible do me and even so, i have outs on turn. I'd be looking to let villian catch up on turn so get a reraise in and possibly commit him to go all-in.

Bacause you said villain can pot on turn with pure blaugh, i would be inclined to check Ax too, to extract on later streets. I would be betting Kx on flop to define my hand though, rather than have a difficult decision if bet into on the turn.

2) Lightest would be Ace rag, kicker 7 or greater. Im on the fence calling with Ace low kicker. Dont really want to call with a king in spot, not much i can beat. JQ scares me, King high kicker scares me, and of course Ace. only thing i can beat with a king is possible busted flush draw.
