In reply to Reach>Talent:
Great thread, reminds me that I should try the new table in our institute (the old one and most of the competitive players have gone to Munich...).
Speaking from years misspent at our local youth club´s table (and after winning our institute league for several years running):
Practise pulling the ball sideways with your attacker and shooting in one continuous movement without losing contact to the ball. Try either shooting directly after passing the defender, or after moving the ball for some distance. Learn aiming at either corner after both moves. Do the same by pushing the ball.
Play with little power in your hands, aim for speed instead. Especially when shooting with the left, slapping the grip with your half open palm is going to be much faster than rotating your wrist.
