oh so you join a novice competition

good for you. Did u win ?
Yes, tomahawk serve can do side spin as well, but tomahawk is a very tiring serve to do, especially on the knee. I had a lot of experience with this serve during my younger player years. You can win points right from it or get killed by doing it, if you do not recover fast after serve especially when your knee becomes very tired. Even Ding Ning is reducing her tomahawk serve nowadays. Tomahawk is only good for top sidespin, very hard to do short side bottom spin with tomahawk, even if you managed to do it, it will be a lousy one. So, still the 2 finger grip on shakehand bat, forward pendulum or reversed pendulum can make very good side-spin of any kind.
Well, if you do not believe what I said about those ball flight reader, nevermind. Next time when you encounter them you will understand or when you learn it yourself, you will also understand. Of cos even if someone can read ball flight/bounce, he will still be looking at contact point of the ball because if the contact is too obvious, there is no need to read ball flight, because much easier to read contacts than reading ball flight.
Try watch closely on your youtube video on professional players, they only watch opponent body language during serve, then see how their eyes track the ball after opponent hit the ball, they are reading flight, they will watch it bounce ( you can see how they pause with their eyes fixed on the bounce )... then only move in for it.
ITTF ban hiding of ball during serve is to protect weaker players. Reading ball flight is difficult and even more difficult for older players with poorer eye-sight. Imagine if everyone have to learn to read ball flight in order to play table tennis, the table tennis game will be so unpopular and will be dead.
Heavy spin serve are slow, plenty of time to see ball flight. So for ball flight, learn it and all your troubles with spin and long pimples will be gone. IF you dont believe, next time you go and play again, stay focused and watch the ball closely after they serve. There is a fixed pattern in ball flight, just deal with the pattern. A lot of time people could not be bothered to learn how to read ball flight. Unless you are too old with bad eye-sight, then no choice but to skip this skill.

There are all sorts of sidespin style, famous tomahawk style by Ding Ning do not need what thumb n fingers u mentioned. Ding Ning sidespin can transition to top+sidespin with angle adjustment or pure sidespin.
TSD i believe when you mention your 'PRO'...they are really just amateur or novice.
Most people used PRO too lightly, I just participate in a local open beginner/novice tournament, the player quality is really very high.
Those who trained professionally will look 1st at the server bat angle and ball contact position (this is why ITTF ban illegal serve with body blocking view).
and the 1st land point(near or further from net) and from there they already can judge the power,type of spin and the 2nd landing point (very important to get into position).
To see the path of flight is already TOO LATE.
There's a hint here to learn to better return serve, watch your server bat angle and ball contact, mirror it when u received. this will be your 'safe' return.
The so call 'PRO' throwing high, swinging left n right like doing magic show is just to confuse you not to let you see the bat angle n ball contact. But once you know where to look it will help a lot to judge serve.
