10-20 Force is a card force, using a mathematical principle, in which a card in the deck is forced on a spectator by asking them to select a number between ten and twenty.
Possibly an old principle, but it first saw print as part of an effect by Billy O'Connor called "After the Four Ace Trick" in The Magic Wand, June-September 1935 (Vol. 24, no. 166, page 85).
