When you play here, there is a chessboard and some buttons. There is an offer draw button, a resign button and a vacation button. The first two are pretty self explanatory.
When you press the vacation button, it does several things. You add 30 days to your clock. If you hit the button, it apparently also adds 30 days to all games you are playing. Some people feel a sudden need to go on vacation right this very minute if a game starts to go against them.
The silver lining to the person not on vacation is knowing that the guy is de facto sitting in a corner in a self imposed time out.
I have read most of the threads about vacation abuse. I still dont understand what it is. It seems to me that either a person has vacation time and chooses to use it or they dont have time and their clock ticks down. What is vacation abuse?
