First of all, while I think there are a few question marks here, none of these hands imo reflect the typical "dry spell tilt" that all of us have. I'd say they're quite solid.
Hand #3 I particularly like. I think it's the perfect spot to limp-re-raise AK.
On hand #1, you essentially answered the question I originally had, which was: Is he a good player capable of calling a raise and playing 86s that way? He obviously isn't, so I don't have any problem with your play on that one.
On hand #2, I've done exactly the same thing except hitting a set with my AA and making the flush. Remember that one from a couple of weeks ago (I posted it)? Against the calling station type, the improvement is completely irrelevant. They just ARE chasing the flush or the straight, so if you can't beat that, you have to just let it go. I did make the call as well, and I don't think it's really tilt-ish doing so, but once you have that read and they end up hitting, you just have to forget it. So it's one I certainly would NOT put in my "stupidity" column, but it's an unnecessary loss. And, with only one heart on the flop, I don't know whether I could have actually believed that even a calling station would take it that far. I mean, all he's got is runner-runner straight and runner-runner flush with that hand... unless I'm missing something.
Anyhow, just my impression from your recent posts: You're pretty much on your game at the moment, maybe with some minor (and debatable) imprecisions which are VERY hard to avoid with that many bad beats. I don't think you need to second-guess your game the way you're playing these hands.
Maybe try another all-in session at the .10/.20... I really liked that one!!

It will definitely turn around at the higher stakes, too. Just keep up the good work!
