The atmosphere of an open chess tournament hasn't changed much in the last hundred years. A visitor from 1948 might wonder at the plush, handmade clothing and the strange haircuts. But the important things-the informality mixed with intense concentration, the wide range of ages, the silence on the floor, the long tables and the rows of players-all would have been instantly recognizable.

Only one important thing had changed, and that might take the hypothetical time-traveler a while to notice: The contestants did not play alone. Teams were not allowed, but virtually all serious players had assistance, usually in the form of a gray box sitting by the board or on the floor near their feet. The more conservative players used small keyboards to communicate with their programs. Others seemed unconnected to any aid but every so often would look off into the distance, lost in concentration. A few of these were players in the old sense, disdaining all programmatic magic. Wili was the most successful of these atavists. His eyes flickered down the row of boards, trying to decide who were the truly human players and who were the fakes. Beyond the end of the table, the Pacific Ocean was a blue band shining through the open windows of the pavilion.

Wili pulled his attention back to his own game, trying to ignore the crowd of spectators and trying even less successfully to ignore his opponent. Though barely out of a Ruy Lopez opening - that's what Jeremy had called it the other night, anyway - Wili had a good feeling about the game. A strong kingside attack should now be possible, unless his opponent had a complete surprise up her sleeve. This would be his fifth straight win. That accounted for the crowd. He was the only purely human player still undefeated. Wili smiled to himself. This was a totally unexpected by-product of the expedition, but a very pleasant one. He had never been admired for anything (unless his reputation within the Ndelante counted as admirable). It would be a pleasure to show these people how useless their machines really were. For the moment he forgot that every added attention would make it harder for him to fade away when the time came.

Wili considered the board a second longer, then pushed his bishop pawn, starting a sequence of events that ought to be unstoppable. He punched his clock, and finally raised his eyes to look at his opponent:

Dark brown eyes looked back at him. The girl - woman; she must be in her twenties - smiled at Wili as she acknowledged his move. She leaned forward, and raised an input/output band to her temple. Soft black hair spilled across that hand.

Almost ten minutes passed. Some of the spectators began drifting off. Wili just sat and tried to pretend he was not looking at the girl. She was just over one meter fifty, scarcely taller than he. And she was the most beautiful creature he had ever seen. He could sit this close to her and not have to say anything, not have to make conversation.... Wili rather wished the game might last forever.

When she finally moved, it was another pawn push. Very strange, very risky. She was definitely a soft player: In the last three days, Wili had played more chess than in the last three months. Almost all of it had been against assisted players. Some were mere servants to their machines. You could trust them never to make a simple mistake, and to take advantage of any you made. Playing them was like fighting a bull, impossible if you attack head on, easy once you identify the weak points. Other players, like Jeremy, were soft, more fallible, but full of intricate surprises. Jeremy said his program interacted with his own creativity. He claimed it made him better than either machine or human alone. Wili would only agree that it was better than being the slave of a processor.

This Della Lu, her play was as soft as her skin. Her last move was full of risk and - he saw now - full of potential. A machine alone could never have proposed it.

Rosas and Jeremy drifted into view behind her. Rosas was not entered in the tournament. Jeremy and his Red Arrow special were doing well, but he had a bye on this round. Jeremy caught his eye; they wanted him outside. Wili felt a flash of irritation.

Finally he decided on the best attack. His knight came out from the third rank, brazen ahead of the pawns. He pushed the clock; several minutes passed. The girl reached for her king... and turned it over! She stood, extended her hand across the table to Wili. "A nice game. Thank you very much." She spoke in English, with a faint Bay Area twang.

Wili tried to cover his surprise. She had lost, he was sure of that. But for her to see it this early.... She must be almost as clever as he. Wili held her cool hand a moment, then remembered to shake it. He stood and gargled something unintelligible, but it was too late. The spectators closed in with their congratulations. Wili found himself shaking hands all around, and some of those hands were jeweled, belonged to Jonque aristocrats. This was, he was told, the first time in five years an unaided player had made it to the final rounds. Some thought he had a chance of winning it all, and how long had it been since a plain human had been North American champion?

By the time he was out of his circle of admirers, Della Lu had retired in graceful defeat. Anyway, Miguel Rosas and Jeremy Sergeivich were waiting to grab him. "A good win," Mike said, setting his arm across the boy's shoulder. "I'll bet you'd like to get some fresh air after all that concentration."

Wili agreed ungraciously and allowed himself to be guided out. At least they managed to avoid the two Peace reporters who were covering the event.

The Fonda la Jolla pavilions were built over one of the most beautiful beaches in Aztlÿn. Across the bay, two thousand meters away, gray-green vineyards topped the tan-and-orange cliffs. Wili could follow those cliffs and the surf north and north till they vanished in the haze somewhere near Los Angeles.

They started up the lawn toward the resort's restaurant. Beyond it were the ruins of old La Jolla: There was more stonework than in Pasadena. It was dry and pale, without the hidden life of the Basin. No wonder the Jonque lords had chosen La Jolla for their resort. The place was far from both slums and estates. The lords could meet here in truce, their rivalries ignored. Wili wondered what the Authority had done to persuade them to allow the tournament here, though it was possible that the popularity of the game alone explained it.

"I found Paul's friends, Wili," said Rosas.

"Huh?" He came back to their real problems with an unpleasant lurch. "When do we go?"

"This evening. After your next game. You've got to lose it."

"What? Why?"

"Look," Mike spoke intensely, "we're risking a lot for you. Give us an excuse to drop this project and we will."

Wili bit his lip. Jeremy followed in silence, and Wili realized that Rosas was right for once. Both of them had put their freedom, maybe even their lives, on the line for him - or was it really for Paul? No matter. Next to bobble research, bioscience was the blackest crime in the Authority's book. And they were mixing in it to get him cured.

Rosas took Wili's silence for the acquiescence it was. "Okay. I said you'll have to lose the next one. Make a big scene about it, something that will give us the excuse to get you outside and away from everyone else." He gave the boy a sidelong chance. "You won't find it too hard to do that, will you?"

"Where is... it... anyway?" asked Jeremy.

But Rosas just shook his head, and once inside the restaurant there was no chance for further conversation.

Roberto Richardson, the tournament roster said. That was his next opponent, the one he must lose to. This is going to be even harder than I thought. Wili watched his fat opponent walk across the pavilion toward the game table. Richardson was the most obnoxious of Jonque types, the Anglo. And worse, the pattern of his jacket showed he was from the estates above Pasadena. There were very few Anglos in the nobility of Aztlÿn. Richardson was as pale as Jeremy Sergeivich, and Wili shuddered to think of the compensating nastiness the man must contain. He probably had the worst-treated labor gangs in Pasadena. His type always took it out on the serfs, trying to convince his peers that he was just as much a lord as they.
