Chess terminology

Gambit - accidental loss of a pawn in the opening
Development - deploying your pieces to squares on which they get kicked around and lose several tempi
First board - weak player who is used as a sacrifical lamb to allow everyone else to have at least some chance of winning
Flight square - escape square for your king, which later turns out to be covered
Good bishop - bishop which is rendered useless by the opponent's pawns
J'adoube - A loophole in the touch-move rule
Novelty - a move which has been played before, but was discarded as poor
Outpost - A fantastic-looking square for a knight, from which it serves no purpose and gets locked out of the game
Sound sacrifice - Giving up material for an attack which succeeds because the opponent was unable to find the correct defence

Lol, excellent billwall. I especially like bad bishop and fool's mate.

To Madhacker and Billwall.. You made me smile with your chess terminologies and their definitions. I wish we have a lot of chessplayers like your kind. Intelligence with sense of humor. 

I am a Filipino but now living in Canada. I am a little bit sad that Canadians are not so keen with Chess. Hockey and Football are their favorites. With their everchanging extreme weather, I don't blame them though.  Thank you to both of you and may your tribe increase.
