The 1986 contest was named: "The Third International Obfuscated C Code Contest"

The rules for 1986 suggested categories due to the success of the 1985
judging method.  The maximum size was increased from 512 to 1024 bytes.
Larry Bassel joined as the second official judge.

A poll was taken for the worst code for BSD and System V program.
The Bourne Shell (/bin/sh) won for both systems.  The BSD finger 
program took third place.

Rules and results were posted to net.lang.c and net.unix-wizards.
Micro/Systems Journal published started regular publishing of the winners.
The practice of making first announcement of the winners at the Summer
Usenix BOF started this year.  A notice was posted to net.announce.
