how to attack under the table high balls....

hello all,

I would like few tips on how to attack when, lets say someone does under-spin, side-under (left or right) from under the table that lands high on my side.

First, it's hard to read the spin (some players can disguise it very well by moving their wrist in one direction and then immediately faking the other direction)
Second, I've heard to counter these balls, just smother and kill, which does work if the ball is only Side-spin, but if it's got under-spin, straight into the net

A lot of times, these balls are high that can be attacked, when I watch videos of Pros, they completely demolish these balls because they're high and to them it doesn't matter what type of spin is on it, as long as its high.
They wait and launch powerful loop or flick at the top of the bounce. Ofcourse, they practice a lot a lot a lot. I want to know what the proper technique to counter and/or attack these types of deliveries.

Bonus Question :): A lot of people talk about racket head speed with forehand/backhand flips and FH/BH loops, my question is that what's the reason for the speed.
My assumption, the faster the swing on top of the ball, it will reverse whatever spin they got on and induce my own topspin


My apologies for the long post....but help is greatly appreciated.

It seems to me like you have a pretty good grasp on all this.  It just takes practice.  If it were easy to hit those balls, people wouldn't perform that under the table shot.

Pros also make mistakes attacking these balls. You just need to increase your spin reading skills :)

would you all agree that it's best to move forward and take the ball on the rise or at the top of the bounce?

Using a more open paddle tends to reduce my errors on this. I rarely hit winners off of it but I tend to keep an advantage in the point.

I guess, it'll have to be something like this to be on the safest side.
Watch closely how the ball is being spin (mostly, it will be either side, under, or side-under)

Scnerio 1, On the FH side:
Then, hit the ball flat because there shouldn't be any spin on that region, then lift and close the paddle quickly with the wrist which is your forehand flick.
Or
Mimic the spin for variety

Scnerio 2, On the BH side:
BH side-top flip as fast as possible on top of the bounce to negate the spin
Or
Mimic the spin for variety

If shot is low and short, then, to be on the safe side, just 'dab' it over
