I'd be intimidated after when I'm playing someone like Roger. If they announce him they could go on for 5 minutes without telling all the records he owns. That must be frightening for other players. Now you really know who your playing....!

warm ups are so contridictory coz they warm there opponent to try and beat them. LOL
