The thing that bothered me the most about hand #2 was the minraise PF. To me, when the play is HU, it absolutely screams AA (unless it comes from an absolutely terrible player, then it could just as likely be KJo). At least try to disguise it a little more, either by (like SonofDjugashvili said), flat calling or pushing. If you had chosen to flat call, and then see the A on the flop, by all means push! The most likely hand, from villains eyes would be a spade draw, and you're semibluff pushing, hoping for him to go away.

I also like the push on hand #1, calling is probably the worst thing you could do. If the table had been tight I wouldn't argue with a fold either, although the lack of a raise from the 2nd pos. seems to be pretty weak.
