Hey
@PenHoldSandro I see your practice BH...
You are doing the shot much like a low power warm-up kind of like you are only trying to keep the ball on the table.
Not much explosion, not much bat speed. You move your upper arm and shoulder during the stroke.
That kind of stroke is OK for a very defensive or neutral resultant ball. That stroke works fine for not giving the point away immediately, but would often result in you losing point on next ball from attack or at a minimum be under serious pressure.
If you want to develop an attacking BH, your biomechanics need to change like NL and Lula are advocating for you to change towards.
However, biomechanics are maybe number three on the big scheme of TT things. A couple things need to happen well before you can use good biomechanics to make a good quality offensive shot.
Number one skill in TT is reading opponent's impact. This means that once opponent impacts ball and the ball travels not even 30 cm... that you know WHAT DIRECTION ball is going, WHICH amount of spin, WHAT type of spin... that you know in 3D the position of the ball when it would pass your endline... that you also know the vector and speed of the ball.
The takeaway from this is you immediately discern this and already formed in your subconscious mind what you want to do to the incoming ball and how.
The number two skill in TT is getting to a good position with enough leverage to make a quality shot to be able to strike ball in effective part of strike zone on time and recover for the next ball.
If a player has decent biomechanics, but cannot do number 1 and 2, then that player is trying to play a strong shot out of position and out of leverage... it is usually a disaster result - immediate lost point.
I have a funny comment I often say when I am chopping a ball to my offensive player friends in practice... when I chop a ball that goes a little inside their strike zone... and they fail to adjust position and comically miss their shot - not even close to landing.
No Position, No Leverage, NO CHANCE.
Many people will give advice assuming 1 and 2 are in order... and often mistakes in reading ball and position/leverage/timing of shot are what makes a poor biomechanic or poor shot.
Biomechanics are uber important. One cannot play quality shots and get to any real level without them.
NL and Lula do great articulating what and how you should structure your biomechanics for the BH - they are worthy to listen to and try to put into practice what they are saying.
