there are actually several valid reasons to fold aa preflop - and that is one of them. though in your situation you were trying to cash and play it safe - which is what i like to do as well - as long as you get to the final table you can always win it. - but some subscribe that winning is everything and then the right move is to call and pray for the best = if you win you got a great chance to win it all- the only close call is that there were only 3 others in the hand - if it was 4 others and you then a fold is a greater play
