Thanks stacks.

"Why would you want him to think you had a Queen here when you have AA."

Simple, because I wanted him to fold. I guess I didn't like the flop and was hoping to be able to take down the raised pot by repping the queen. But I do realise that this is bad logic. I understand what you've said above, and I really will try to apply it to my game. I don't want him to fold if he has a range that is losing to me. And if my range is losing, then it's a question of how far behind I am, and pot odds.

" If you fail to assess villain's range on every street, and how your hand plays against that range, then you are losing money. AA is not an exception. "

And with this you've probably nailed the reason I found myself losing one big pot and winning four small ones with aces, and the reason I went for the shove option for a week. While I accept shoving is not the most profitable way of playing aces, it's a guaranteed profit nonetheless. But I do want to maximise my profits with aces. I suspect I'm guilty here of attempting to keep my profit with aces as high as possible, ie folding for cheap when they're losing, but I'm not sure I was losing, and even if I was, you're right, I should fold to his donk bet if I put his range that tight that aces are losing, and I don't have the required pot odds to continue.
