paid him in spades
In contract bridge, as well as a number of other card games, spades are the highest-ranking of the four suits (clubs, diamonds, hearts, spades.) Thus a bid in spades outranks a bid in hearts. By extension beyond cards, "in spades" expresses a decisive, complete, no-doubt defeat. If I suffer a (real or imagined) injury from you, and I retaliate with disproportionate vigor, I have paid you back "in spades."
