Mind you, the above definition does not always apply and the master can display greatness in other ways. For example, Austrian master Josef Krejcik gave a simultaneous chess display on 25 boards in 1910. Nothing unusual about that, except he went on to lose every single game.
This acheivement was surpassed by a New Jersey chess player. He invited 180 opponents to play him in a simultaneous exhibition. This would have been a major success and of no interest. However, his task was made considerably easier when only 20 people turned up. Not allowing this to deter him, he went onto greater heights by losing all but two of the games. Of these two games, one was against his own Mother!
