Good words, iffy definitions.
More interesting (to me) would be something like:
Bad Bishop - a man in the wrong profession.
Spite Check - a self evaluation of one's bad attitude.
Luft - using a German aircraft to open up the castled king's position.
Underpromotion - umm... let's not go there.
Skittles: A slang term for unofficial chess games, most often played quickly. I thought this was candy. LOL
Duffer: A slang term for a very poor player. Also called woodpusher, patzer. This one was my favorite.
Spite Check: A check given by a player facing the inevitable checkmate of his own King. A Spite Check does not eliminate the threat of checkmate; it merely delays it for a move or two. Don't even get me started.
Bad Bishop: A bishop that is blocked in by it's own pawns which rest on the bishop's own color.
Cheapo: A slang term meaning a cheap trick that results in a won game or won material. Also called Swindle
En Prise: A French term meaning "in a position to be taken". When a piece is placed in a position to be captured wherein the enemy piece cannot be re-captured. Also called "leaving a piece hanging".
J'adoube: French term meaning "I adjust".
Kibitz: A comment during the game or during analysis afterward, within the hearing of the players. Refers most often to spectators. One who kibitzes (called a "kibitzer") during the play of the game can be, at the request of the players or by ruling of the Tournament Director, removed from the playing hall.
Luft: A German term meaning "air". One creates "luft" by giving the king an escape square
Underpromotion: Promoting a pawn to any piece other than a Queen.
Zugzwang: German for "compelled to move". A situation that occurs when any move a player makes will weaken his/her position, however, he/she is compelled to move in accordance to the rules.
