Used in sports to describe a great move that makes someone else look useless.
Come from the card game 'Euchre' where if spades/clubs are selected as the trump the 9 of hearts becomes a worthless card that can't beat any other card. After the deal, when the trump is selected the dealer may give a card from his hand to another player in exchange for the trump card. If you "give them the ol' 9 of hearts" you've given them something that can't possibly win a hand, a useless card.
something used to describe a filthy move (most likely backhand to forehand) ala Tyler Ennis. Used most frequently (and to this date only) by TSNs worst colour commentator Darren Pang
Gord Miller: "Take it away Panger"
Darren Pang: "Holy Jumpins!, Gave em the ol 9 of hearts.."
