"Don't move until you see it...."

In my early 20s i used to hang out with this guy John. John was a chess genius. When i say chess genius i don't just mean he was better than me; John was better than everyone. He was the type of chess player that could tell you that you only had 20 moves left before he beat you. I watched him hustle the hustlers downtown in the park every Sunday, even though the hustlers knew him, and knew they would lose-they played him anyway, just to figure out a way to beat him. I never saw him lose. I even watched him play 5 chess games at once against 5 opponents and win every one.
When i watched John play, i could see his eyes flutter from piece to piece on the board, and would be amazed as i watched him calculate outcomes in ways you could physically witness if you watched closely enough. I never once beat John at chess.
John and i have since gone our separate ways, and i lost touch with him years ago. But i will never forget the look on John's face every time he saw the weakness in your advance. You could almost tell the moment he actually won the game, before it was even halfway finished. I get that same feeling playing Thinking Machine 4: a chess program that visualizes each move as the computer considers it. Watching the colored lines emanate from the individual pieces is just like watching John's eyes bounce from position to fragile position, calculating the eventual outcome of each move. And while it is entirely possible to beat Thinking Machine 4 in a game of chess, it is terribly daunting to watch it orchestrate your demise while doing so. Play the game, and see how you do. Who knows. Maybe it will help prepare you if you are to ever sit across a chess board from John Pyles; in which case, may he have mercy on your soul.
