Taking a dive in the penalty box

It is not only soccer where you see players rolling on the ground in agony, trying to milk a penalty from the referee. Sometimes it happens in Chess as well (although not in quite the same way).
With the football World Cup currently on, and a number of players looking for Academy Awards for their acting prowess, I am reminded of a game from the 2006 Olympiad.
New Zealand Board 3 FM Roger Nokes was playing against Costa Rica, and from the outset he had had the upper hand. His attack had rolled along quite smoothly and by move 34 he was up a piece, and had a forced mate starting with 35.Qc3. But at some point while executing a move (I do not know which one exactly) he had bumped another piece, apparently upsetting it. According to the New Zealand Team Captain Hilton Bennett, his opponent took one look at this and then "went down like a striker in the penalty box". There was much gesticulation, the calling of arbiters, and general umbrage from the Costa Rican player concerned. After some argument about what had happened, and what should then happen, the position was restored and the game continued. However this break in concentration did Roger no help at all, and after missing the win (and subsequent ones), his position began to slowly go backwards. A dozen moves later a draw was the best Roger could hope for, and another dozen moves after that he was lost.
