In one of the most outrageous acts of Grandmaster chess ecsentricity ever, Grandmasters Aron Nimzovich ("My System") and Friedrich Samisch went head-to-head in the last round of the classic 1925 Baden-Baden Tournament, just outside Berlin, with first place hanging in the balance.   Upon the game's ending, when the superior Nimzovich was about to be mated, he suddenly jumped up onto a table, got down on his knees and screamed,   "Why must I lose to this IDIOT!?"   There are many variations as to how Aron expressed his angst that day at the prospect of not winning the tournament, but this particular variant came from the "Idiot" himself, Friedrich Samisch!
