Are you still smarting from the blunder that made you lose your game against another amateur in your chess club? You would surely wish that you got to play against Nimzovitch or Rubinstein, two of the stalwart Grandmasters in the field of chess, as you might fare better if the following position is any indication!
Both the players made moves before and after this position was reached, oblivious of the fact that a mate in two existed (1. Qxf7+ Kh8 2. Qxg7#)!
The occurrence of these blunders is all the more startling in view of the fact that the players were competing for the first position in a tournament and this game would decide the winner!
