The number of chips a player has determines many of his decisions. Greater depth allows you to use hands with "long" equity - they are not strong in preflop all-ins, but when they hit the right boards, they turn into monsters. And with shallow stacks, preflop ranges shift towards hands that are strong in shoving. These are aces, broadway cards, pocket pairs.
