Yes, let's list 5,000 signs!!! It may sound crazy, but I think, altogether, we can do it!

1. You castle by stacking your rooks on top of each other and putting your king on top
2. You think there is a way out of checkmate
3. You think pawns are more valuable than your king because they can promote

It'll never get to 5,000.  The "1000 signs your play chess too much" is around 300 after a month or two.

When playing white, this is your favorite opening.

5. You stink at chess.

6. You think you created a new checkmate with this:

7. You don't know what you call it when you develop a bishop on g2, b2, b7 or g7

You can win every game, or draw if the game was played perfectly. If you can't do this, you don't know everything about chess.

#8:  This is a winning combination!

#10:  you fall for #6!

#11:  You think all developing moves with the bishop to g2/7 and/or b2/7 are called fianchetto!  :-p

#12:  You think my diagram with this post is winning for black.

13. You sac all your pieces to eliminate all of your opponent's pawns, now he won't be able to get a new Queen! Brilliant!

Haha, great one!!

14. When castling OTB, you first move your rook, then the king.

15. You always have arguements with your friends about if the a4 move is better, or the h4 move.

16. You think that Morphy is some dude from The Matrix.

17. When you hear people talking about Ruy Lopez, you think it is a drink and ask if you could have one but with a twist of lemon.

18. You refuse to play "The Itailian Game" if you're not eating pizza.

19. You're don't know what the Itailian Game is.

;p

20. When a pawn captures your queen, you start saying that it isn't fair:
"A small insignificant pawn like this has no right to capture her majesty!"

21. U look at the knight pieces and said.. , are they horses ??

22. You look at the knight piece and you think that the rider must have fallen off at some point.
