Watch The Game On The Table Next To Yours
This shows a fundamental lack of interest in one's proper game, and as such a lack of respect for one's opponent. Games at other tables are interesting, and I might go for a stretch myself during a long tournament game, but once seated, one should pay attention to the game one is playing.
Although I agree with you in principle, I would like to add a corollary: If your opponent is constantly looking at other tables around you, play quicker. Especially at club evenings where there is no clock, I sometimes get bored (I show a lack of interest in my own game, maybe) while my opponent thinks and thinks and thinks - only to play the obvious move ...
Reminded me of another bad habit: Too Much Thinking. --Matt Noonan
What if the other game in question is being contested by two attractive candidates? ;-) -- ~ian~
Stefan: Then you're not watching the game, and it's perfectly OK.
Sometimes I do watch the game on the other table when my opponent wants to ContinueWhileDozensOfPointsBehind.
