Gridley

Gridley learned the power of transfer because, as a young piece, he treated every new game as starting from zero.

Each time he met a new game, he'd groan — another whole set of rules and tricks to memorize from scratch, as if nothing he already knew could help. Learning felt like an endless pile of unrelated things, and it exhausted and discouraged him. He was sure some pieces were just "naturally good at games" and he wasn't.

An old host of the arcade changed his whole view with one question. Gridley had just learned the fork in Connect-4 — one move, two threats. The host walked him to the Gomoku board. "Look for it here," she said. Gridley protested that this was a different game. "Is it? You just learned to make two threats at once. Can you do that here too?" He could — a "double three" was the very same idea. Then Hex: a "bridge" was two safe paths at once, the same idea again. Gridley was stunned. The thing he'd learned in one game had walked straight into the next. He hadn't been starting from zero. He'd been carrying his ideas with him the whole time and just not noticing.

He came to the GridForge academy as its mentor — the one who connects all five games. On his first day the head asked what he taught that the specialists didn't.

"They each teach one game's move," Gridley said. "I teach where that move shows up again." He pointed down the row of boards. "Rowan's connection is in Connect-4, Gomoku, and Hex. Twain's fork is in Connect-4 and Gomoku. Flank's flipping is Reversi. Oddwin's parity is Dots-and-Boxes — and it's the same 'who-moves-last' idea as the checkers endgame next door. Once you see the four ideas, every new game gets easier, because you've met most of it before."

"Most mentors teach games," the head said. "You teach transfer." And that has been Gridley's role ever since: the host who turns five games into four reusable ideas.

A discouraged young piece came to him. "There are so many games. I'll never learn them all." Gridley grinned; it was his own old despair. "You don't have to learn them all as separate things," he said. "Come here." He walked the young piece down the row, naming the shared idea at each board. "Connection. Fork. Flip. Parity. That's almost the whole arcade, right there. When you meet a new game, don't ask 'what are all its new rules?' Ask 'which of the four ideas does this one use?' — and suddenly you already know half of it." The young piece looked down the row and, for the first time, didn't see five walls of rules. It saw four familiar ideas wearing five costumes.

"That's the secret nobody tells you," Gridley said. "Learning isn't an endless pile of separate things. It's a handful of big ideas that keep coming back. Spot them, and everything new gets easier."
