Range and stack, as it is interconnected, there is something to think about. Having good cards like AQ is not a reason to part with a deep stack, these cards are good but not strong enough, then you need to play starting with AK, AA, QC, maybe QQ. This is when you have a small short stack there is no choice, you need to play with the cards that are dealt, because the blinds very quickly eat short stacks, and when a large stack has something to think about, do not rush, players with large stacks often lose because of the rush.
