"He's trying to stall," said the Commander, gnawing a thumbnail. "We won't be
able to offer any advice, with that thing listening. Oh, stay sharp, Del boy!"
"To simplify matters," said the berserker, "I will move first in every game."
Del could look forward to another hour free of the mind weapon when he
finished rigging the checkerboard. When the pegged pieces were moved,
appropriate signals would be radioed to the berserker; lighted squares on the
board would show him where its pieces were moved. If it spoke to him while
the mind weapon was on, Del's voice would answer from a tape, which he had
stocked with vaguely aggressive phrases, such as: "Get on with the game," or
"Do you want to give up now?"
He hadn't told the enemy how far along he was with his preparations because
he was still busy with something the enemy must not know-the system that was
going to enable Newton to play a game of simplified checkers.
Del gave a soundless little laugh as he worked, and glanced over to where
Newton was lounging on his couch, clutching toys in his hands as if he drew
some comfort from them. This scheme was going to push the aiyan near the
limit of his ability, but Del saw no reason why it should fail.
Del had completely analyzed the miniature checker game, and diagrammed every
position that Newton could possibly face-playing only even-numbered moves,
thank the random berserker for that specification!-on small cards. Del had
discarded some lines of play that would arise from some poor early moves by
Newton, further simplifying his job. Now, on a card showing each possible
remaining position, Del indicated the best possible move with a drawn-in
arrow. Now he could quickly teach Newton to play the game by looking at the
appropriate card and making the move shown by the arrow-
"Oh, oh," said Del, as his hands stopped working and he stared into space.
Newton whined at the tone of his voice.
Once Del had sat at one board in a simultaneous chess exhibition, one of
sixty players opposing the world champion, Blankenship. Del had held his own
into the middle game. Then, when the great man paused again opposite his
board, Del had shoved a pawn forward, thinking he had reached an unassailable
position and could begin a counterattack. Blankenship had moved a rook to an
innocent-looking square and strolled on to the next board-and then Del had
seen the checkmate coming at him, four moves away but one move too late for
him to do anything about it.
The Commander suddenly said a foul phrase in a loud distinct voice. Such
conduct on his part was extremely rare, and the Second Officer looked round
in surprise. "What?"
"I think we've had it. "The Commander paused. "I hoped that Murray could set
up some kind of a system over there, so that Newton could play the game-or
appear to be playing it. But it won't work. Whatever system Newton plays by
rote will always have him making the same move in the same position. It may
be a perfect system-but a man doesn't play any game that way, damn it. He
makes mistakes, he changes strategy. Even in a game this simple there'll be
room for that. Most of all, a man learns a game as he plays it. He gets
better as he goes along. That's what'll give Newton away, and that's what our
bandit wants. It's probably heard about aiyans. Now as soon as it can be sure
it's facing a dumb animal over there, and not a man or computer... "
After a little while the Second Officer said: "I'm getting signals of their
moves. They've begun play. Maybe we should've rigged up a board so we could
