As soon as he sees the return coming back up the centre of the court Agassi starts to move to his left looking to bring his forehand into play.

His opponent is now stuck in the middle of the court knowing he's in trouble, as Agassi could attack either forehand or backhand next.

Agassi gets into position to make sure that there is no difference in his set up so he can hit down either flank.

This would allow his opponent to anticipate which way to go.
