Hey Gabriel, I don’t think this needs to be your default placement but it is something that you can definitely make use of a lot during games to make players uncomfortable as you said. In table tennis it’s always important to have variety and options in your game because each different player will find different things hard. So for sure work on this and get really comfortable with it and it can be a great weapon in your game. But with anything good, if you overuse it all the time players will get used to it and adjust. So mixing it up and keeping people guessing is even more important. Tom
