Entirely left-handed.
I moved from tennis to table tennis and mostly learnt the old-fashioned way: by playing people much better than me, losing to them, and slowly figuring out why.
YouTube filled in some of the gaps. Somewhere along the way I picked up a few serves and tricks, including the pendulum, tomahawk and backhand sidespin.
