Honest Chess Player: Check.
Dishonest Chess Player: What do you mean? Define "check". (Questioning the validity of the word and a delaying tactic)
Honest Chess Player: You are in check, it's your move.
Dishonest Chess Player: Hey, what's that standing behind you? (Dirty delaying tactic)
Honest Chess Player: You are still in check, are you going to move?
Dishonest Chess Player: You're just a sleazy hater of blacks (chess pieces) which is why you made that move. (Contrived personal attack)
Honest Chess Player: That's enough. Either make a move or concede.
Dishonest Chess Player: Aaaaaaaah Choooooo! ("Accidentally" knocks all the pieces off the board whilst "accidentally" sneezing)
