Personally - i have over a lengthy period of time (and time out) compiled a set of notes on pretty much every player in CC, especially those who play a lot of games and those who tend to deep run more so than others.
Why? well because of situations like above where im holding AA - there are certain players im happy to go to the river against with this monster pair and others that i will look to extract the max value from leading up to - by now you tend to know the ones who chase flushes or open enders or set mine.
Its not an exact science, you will fall foul now and again but generally speaking its one of the reasons why my heads up game is so strong.
CRStals makes a very important point - if you are going to go all the way, have a plan or at least, the journey is as important as the end result, i have folded big hands many times when i have suspected someone has got there - its led to being bluffed and its led to me winning tournaments, the balance for me is more positive than negative and i stick to that.
There are several ways i play AA and i am not going to give that information away on here

but its very situational, it can be also dependent on who is in the pot with me, the value and much more. I will say this though, isolating players is one key strategy i use, it is not just about position on the table for me, if I am going to play, then i am going to often make my opponents PAY to tag along and i will commit them to the pot.
