Time to Sacrifice the Queen
During an international chess competition many years ago, a man named Frank Marshall made what is often called the most beautiful move ever on a chess board. In a crucial game in which he was evenly matched with a Russian master player, Marshall found his queen under serious attack. There were several avenues of escape and since the queen is the most important offensive player, spectators assumed that Marshall would observe convention and move his queen to safety. Deep in thought, Marshall used all the time available to him to consider the board conditions. He then picked up his queen—paused—and then placed it down on the most illogical square of all. He placed it in the square that the queen could be captured. He placed it in front of three of the most hostile pieces of his opponent. There was no way the queen would be able to withstand the attack.
