I created a WordPress plugin to display small poker cards in blog posts. Once you install the plugin you can use the nomenclature of:
[Ac]
to show the card of Ace of Clubs for example. You use a two-letter code that is Rank and Suit to show a card. The ranks/suits are as follows:
Ranks: 2, 3, 4, 5, 6, 7, 8, 9, T, J, Q, K, A
Suits: c, d, h, s, x
where c=Clubs, d=Diamonds, h=Hearts, s=Spades, and x=Unknown
So go ahead and tell people how you had your [Ad][Ah] cracked by a donkey with [5c][8c] !
