This is A Perfect Fit by Isaac Asimov.

Punishment for cybercrime:
Bradstone leaned forward in his chair and said, intensely, "If you've
followed my case, you must know I have been subjected to cruel and
unusual punishment. I'm the first person who has received this kind of
sentence. The combination of hypnosis and direct neuroconditioning has
only been perfected recently. The nature of the punishment to which I
have been sentenced could not be understood. It must be lifted."
Gold said, "You underwent due process in great detail, and there was
no reasonable doubt that you were guilty—.
"Even so! Look! We live in a computerized world. I can't do a thing
anywhere—I can't get information—I can’t be fed—I can’t amuse myself—I
can't pay for anything—or check on anything—or just plain do
anything—without using a computer. And I have been adjusted, as you
surely know, so that I am incapable of looking at a computer without
hurting my eyes, or touching one without blistering my fingers. I
can't even handle my cash card or even think of using it without
nausea."
The chess part:
He turned away bitterly and noted a makeshift setup of eight chess
boards balanced on pegs, one above the other.
Ordinary chessboards. Plastic chessmen.
"Hey," he said in explosive surprise.
The young man at the multi-board said, defensively, "We can't get
close enough. I set this up myself so we can follow. Careful! Don't
knock it down."
Bradstone said, "Is that the position as of now?"
"Yes. The guys have been arguing for 10 minutes."
Bradstone looked eagerly at the position. He said, raptly, "If you
move the rook from beta-B-6 to delta-B-6, you get the upper hand."
The young man studied the board. "Are you sure?"
"Certainly I'm sure. No matter what the computer does, it's going to
end up losing a move to protect its Queen."
More studying. The young man shouted, "Hey, in there. Guy here says
you should bump the rook up two levels."
There was a collective sigh from the inner group. One voice said, "I
was thinking that."
Another said, "I get it. It leaves the Queen with the potentiality of
vulnerability. I didn't see that." The owner of this second voice
turned. "You! The fellow who made the suggestion. Would you do the
honor? Would you punch in the move?"
Bradstone backed way, his face contorted in sheer horror. "No—No—I
don't play." He turned and hastened away.
Inability to even use a credit/payment card (tries to get a boy to do it for him):
Bradstone made no move to come closer. If he did, the boy would
undoubtedly run. He said, "I'll bet you're big enough to do your own
ordering. You can order a hamburger or anything else, I'm sure."
Pride overcame suspicion. The boy said "Sure! Any time!"
"But you don't have a card of your own, right? So you can't complete
the order. Right?"
The boy started at him warily out of brown eyes. He was neatly dressed
and had an alert and intelligent air about him.
Bradstone said, "Tell you what. I have a card and you can use it to
order. Get yourself a hamburger or anything else you want. Tell you
what else. You can get me something, too. Nice T-bone steak, and a
baked potato and some squash and some coffee. And two pieces of apple
pie. You have one."
