Is being left handed on advantage ?

It’s not real  advantage ,but usually it’s easier to play against right handed players ,this is simply , because there are more right-handed  players ,so you are more used to practicing and  playing against them ,also when you play against left handers  ,the sidespin come in the opposite way and you have to readjust the ball placement  ,So there is a  small advantage ,if you can choose ,I  would recommend playing  in left handed .

So for  obvious reasons ,it’s not allowed  to move the table
