Re:Can anyone thking of any drugs (Score 2, Informative)

As a professional chess player of 12 years, I would much rather play against some taking some sort of drug. As every chess player will tell you, in order to win a tournament you will have to play your best over the course of DAYS, not simply a few hours. Ridilin or Adderol would probably be likely choices, yet they both will lead to disrupted sleeping patterns and would overall hinder a performance the following days.
