One doesn't just jump out of a high rise window. Why on earth would Bardeleben do that. If he was alone at the time and had dizzy spells---maybe he was opening the window for fresh air and fell out. Maybe he walked out of a tournament in the middle of a game and his opponent was pissed and snuck up to his room and pushed him out the window. Maybe he was high on dope and thought he could fly. If we put our heads together we could solve this mystery! And others. Like why didnt Schlechter draw that last game against Lasker?? Or perhaps we could discover who was crazier, Fischer, Rubinstein or Morphy. Or did Kasparov really cheat Judit? Did Keres throw all those games to Botvinnik in 48'? Spread out---SPREAD OUT---start beating the bushes. If you find any clues report back to headquarters.
Our word for today is "defenestration". Use it everyday in everyway and you will own this word!
