Origin of "Spader"?

I know “Spader” is a common term to refer to people who try to find out the inner workings of video game mechanics. I vaguely remember that it came from an article talking about the four types of video gamers, and how they corresponded to suits (Hearts=Socialite, Clubs=PVPer, Diamonds=101%/Speedrunner, Spades=Base Mechanics data collector). But I can’t for the life of me find the article from which these terms came. Can anyone help?

This may get a better response in The Game Room than GQ.

Thank you!

Also, this is humorous in its detachment:

And I am totally a Diamond.

used to be clubs, now i am halfway between hearts and diamonds =)
