question:  Who is putting on the chess tournament? Why?
context: Chess sets were everywhere—big ones on tables, still bigger diagram-type electric ones on walls, small peg-in sets dragged from side pockets and manipulated rapidly as part of the conversational ritual and still smaller folding sets in which the pieces were the tiny magnetized disks used for playing in free-fall. That Siamese-twin clocks should be essential to a chess tournament struck Sandra as a particularly maddening circumstance. Samples: "They say the Machine has been programmed to play nothing but pure Barcza System and Indian Defenses—and the Dragon Formation if anyone pushes the King Pawn." It is a game for lunatics—or else it creates them. "You know nothing whatsoever of chess—so you will be able to write about it understandably for your readers." You want to know why, if the Machine works at all, it doesn't work perfectly, so that it always wins and there is no contest. What the Machine can do is examine all the likely lines of play for about eight moves ahead—that is, four moves each for White and Black—and then decide which is the best move on the basis of capturing enemy pieces, working toward checkmate, establishing a powerful central position and so on." In crucial situations, say where there's a chance of winning at once by trapping the enemy king, he examines many more moves ahead than that—thirty or forty even. But in most chess positions the possibilities are so very nearly unlimited that even a grandmaster can only look a very few moves ahead and must rely on his judgment and experience and artistry. Flesh-and-blood chess masters have lost games by blunders they could have avoided by looking only one or two moves ahead. In the middle, toward the far end, were five small tables spaced rather widely apart and with a chessboard and men and one of the Siamese clocks set out on each. Two of them had just laid a black cable to the nearest chess table and were attaching it to the Siamese clock.
