1,000 signs you play chess too much.

There are 20 posts per page, 20 * 67 (it's an overestimate since this page hasn't reached 20 comments, but it works in favor of my point) = 1340, there are at least around 5 or more irrelevant or repeated or deleted comments per page, so 5 * 67 = 335. 1340 - 335 > 1000, but when we add all the irrelevant comments greater than 5 per page (these numbers experience an increasing positive correlation with increasing # of comments and a decreasing positive correlation with fewer comments), 1340 - x is likely to be < 1000. This, however, is just theory supported by weakly supported evidence, so you may be right. Counting is much more accurate.

#1001 When you start calculating and estimating the amount of posts in an off-topic forum.
Couldn't have said it better myself. (and I'm pretty good at saying stuff!) ;-D

3 signs you play chess too much:
1. You always dream something about chess
2. You always think about chess (even talking about soccer)
3. You are not better in chess, but, you are always talking about chess every and anywhere

111. You begin quoting "Chess is life", "Chess imitates life", "Life is like a game of chess".
Or you say, "Chess is not dead! Chess is life!" (A paraphrasal of a line from the movie Mystery Men, for those of you who don't get the joke.)

You have a nightmare where you are a pawn on a large open-air chess board and are about to be taken by the other side's queen towering above you then you wake up at 3.am and discover your gf has got you in an odd situation.

Nothing intimidating but the juxtaposition was vey similar to the one on the oversized chess board in the dream I had
And also when you memorize all the possible openings and their variations' names
Good one! (I haven't -- all those names crack me up! :-D )
