A tight rack transfers the energy of the cue ball through the entire rack immediately, while a loose rack has gaps that must be filled from the ball just struck in front of it, creating more friction and therefor losing more energy. For the best spread on a break, make sure all the balls are touching. If the other player thinks the rack is not tight, he/she is allowed under the rules to demand a re-rack.
