"DISHONISCHENKO SYNDROME" - FOUND ANYWHERE IN TABLE TENNIS.

For those who do not know, Boris Onishchenko, born in 1938, a Soviet Olympian, pentathlon, had incured a lifetime disqualification because he used a tricky technical gadget during a fencing tournament. He deliberately made this indecency because he really wanted a gold medal, wanted to win glory and money, but his young physical strength was already gone, and his mental confidence failed him before the competition. According to sports journalists, the case of Boris Onishchenko is the most infamous sports deception of the XX century.

However, sports journalists are not familiar with the indecent doings by table tennis veterans. Onishchenko syndrome is not uncommon in a veteran player, this is rather a widespread case. Elderly players are people with avid ambitions, and they're striving to be the upper dog even if the young reactivity has gone and all the body limbs weakened.. Inspirited to compensate for their physical infirmity, veteran players deliberately use rubber with deceptive long pimples as developed by Herbert Neubauer of Germany, a veteran player obsessed with a similar syndrome. What is still worse, veteran players have come up with a lot of technical tricks to enhance the deceptivity of the pimples, and those tricks all go against the rules of table tennis 2.4.7. Those deceptive materials are now most welcome amongst veteran players, because impunity of the cheaters.

WHAT'S TO BE DONE
It is not unfeasible to unveil a cheater who treated pimples secretly. To begin with, we need a control tool to umpire's hands.
