I wish I had a little more info, but I am sorry to hear, djasset, that you are having such a rough time busting with AA. I have to admit that I have yet to play in a CC daily free roll, but I have gone through the same experience both in online and live play. And, as you can imagine, it does not feel good when that happens with "odd ball one outers" on the river.
In an honest game, online or live, I don't think that there is any real way around that circumstance, short of not shoving all-in where possible (!?). Sometimes busting with AA is just the way it goes. But, it does concern me that this happens so often to you with "odd ball one outers" on the river.
From my experience, and probably from your own, I find that AA is often busted where there are many players going to the river, and less so when there are only one or two. But, so many times with one outers? That is a bit strange. In your position, if possible, I might take note of the names of the busters and the countries from which they come. It would be interesting if the same names show up in different games in similar circumstances.
Best wishes, and better luck.
