Recently there was a discussion about a new element in Federer's play which some journalists dubbed sneak attack by Roger or SABR.
What exactly this shot/point build-up is?
What type of player can successfully use this tactics? What abilities does a player need to be able to take an advantage of this? (Probably also weaknesses of the opponent play a role here?)
This recent post is, to some extent, related - although it asks about this with relation to tennis rules: How far is too far for Roger Federer?
