Answers.Body: <p>In a game I was personally playing in, my opponent was a first-time tournament attendee.  It was an early round and I would say the position on the board was about equal.  But my opponent made a blunder that left him open to a mate-in-one, which I found.  He got angry, and used his arm to sweep the pieces off the board, on to the floor.  Then he stormed out of the tournament hall.  He did not come back for the next round, I don't think he ever played another tournament game again.</p>
  
  <p>I've seen (as a spectator) a well known local player in our city get upset with himself during a game because he blundered in a good position - he picked up the clock and threw it hard against a wall, breaking it.  Fortunately (sort of...), it was his own clock.</p>

  Trash talking during a game and calling the opponent fish or patzer. Usually only seen during casual games with relatively fast time controls.
  
  I have seen it with IMs and GMs doing it , usually I think in 'fun' without an evil intent, but sometimes it is definitely meant to win unfairly especially when they have money on the game.
