117. Wiping your potato chip crumbles all over the board.
Worst Thing To Do On Your First Move
118. Playing the Bowla Del Mar variation of the Ruy Lopez instead of the Plata Del Mar, because you feel it's better for liquifying the position.
119. Wearing a football helmet, tackle your opponent and tell them you've already put them in an absolute pin even before the first move.
121. Breaking open your opponent's fleabag he was saving up to take to the flea market and all the fleas get loose, then your opponent starts crying.
122. Crying all over the king, and then he slips and falls off the chessboard and your opponent says you resigned.
191. Wrapping your opponent's pieces up in aluminum foil before his first move, because your coach told you to try to foil his plans.
192. Attaching three more fingers on your left hand and three more fingers on your right hand, so you can touch all the pieces simultaneously; that way your opponent can't use the touch move rule against you.

116. Fanning your buttocks too much before the first move.
