Eg I find it can work on the 1st serve against S&Volleyers,
How do you think it could work on 1st serve against S&Volleyers?
Your opponent attacks the net behind the 1st service.
You chip return and run to the net as well.
sure, there is the point of surprize for the opponent, but you will probably be in the "no man land", so your opponent will have plenty of options how to play the point further.
I was wondering whether people thought this tactic will be employed much in the future? Do you have any ideas on how to train the sabr? As well as what sort of techniques can be effective in its execution? What footwork is most effective? (Do you start further back and move forward quickly?)
Fed was usually entering inside the court, so that after chipping he can cover the net easily.
I have seen this live many years ago, at a junior ITF competition.
The player that did it, was as well doing it from inside the court.
Another parallel, it worked well versus opponents of lower level, but by the time when the guy reached the final, he wasn't employing the sabr anymore, and his return position was as well rather standard.
Fed stopped using it after Novak showed the world that it is possible to counter-act sabr: lob, passing shots and of course mixing the two.
so in summary, if you are good at the net, and your opponent has a weaker wing, it makes sense to employ sabr.
but if your opponent is of similar level, or higher level, and there is no weaker wing, it can be countered.
