Story where someone gets disconnected from computers for cybercrime

I read a short (in the range of 5-20 pages) science fiction story a while ago, and can't remember the title of the story or its author at the moment.

The basic story is that of a super-savvy computer hacker who got all of his knowledge of computers removed from his brain, temporarily (one year?) for cybercrime, including (IIRC) some form of identity theft, and is released into the public without any jail-time or anything. This is very hard on him, for this future-Earth relies heavily on highly interconnected computers for basic and daily needs.

This is not immediately clear at the start of the story, but it becomes apparent after a little while.

Part of the story includes the main character (I don't remember if he is granted a name in the story) wanders into a cafe or a bar, and is invited to play a game of digital, tridimensional chess. He has to turn down the invite, though, because he doesn't know and is blocked from knowing how to use computers. He also really doesn't want the other characters to know this, because apparently having your computer knowledge removed from your brain for cybercrime is a major stigma in that society.

The character also has difficulty using his (futuristic equivalent of a) credit card, as that also requires some computer knowledge.

Any ideas?
