I was watching a game last week where one player got away with easing over and blobbing up in front of an oponents blob. The opponent didn't notice the move (doh!) and was setting themselves up for a mixi... the sepctators kept quite for a bit, but eventually their comments brought the game to a halt and forced an explanation and admission. Resetting the pieces was a challange a bit like that faced by a Snooker Referee after a bit misshit... but great entertainment value!!!
