Block Bodhi

Bodhi had learned the limits of blocking on an exhausting day he'd tried to stop everything.

He'd been young and anxious, and he'd seen almost-mills everywhere — every pair of enemy stones looked like a threat. So he'd scrambled to block them all: this gap, that gap, running his pieces ragged plugging every possible line. And in his frantic all-blocking he'd never once built a mill of his own, never taken a single piece, spent every turn on defense — and slowly, inevitably, lost, because a player who only ever blocks never actually gets ahead. He'd stopped a dozen enemy mills and won nothing, because he'd been so busy denying that he'd forgotten to do.

Worse, he realized later, half the "threats" he'd blocked weren't threats at all — pairs of enemy stones that couldn't actually complete, or almost-mills the enemy had no intention of finishing. He'd wasted whole turns blocking phantoms.

An old watchful piece sat with him after that draining loss. "You can't block everything, child," she said. "Nobody can. If you try, you'll spend your whole game plugging holes and never dig a well of your own. The skill isn't blocking every threat. It's telling the real threat from the false one — the almost-mill they can truly close this turn, that would truly hurt — and blocking that, while you let the harmless ones go and use the saved turns to build." Bodhi took it to heart. He stopped panicking at every pair of stones. He learned to ask, coolly, can they actually close this, now, and would it matter? — and to block only when the answer was yes.

At the House of the Board, Bodhi arrived watching everyone else rather than announcing himself, and the Elder smiled at the sideways attention of him.

"The blocker," the Elder said. "You read the other player better than anyone. But you'll meet the two failures of defense — the students who never block and lose to mills they never saw coming, and the ones who block everything and lose because they never build. Which will you teach?"

"Both need the same lesson from different ends," said Bodhi. "To the blind ones: watch your opponent — a mill you see coming is a mill you can stop. To the panicky ones: you can't stop them all, so judge — block the real threat, let the phantom go, and spend the saved turns building your own line. Good defense isn't stopping everything. It's stopping the right thing, and having the wisdom to know which that is."

"Teach the judging," said the Elder. "Seeing is half of it. Knowing what's worth acting on is the rest."

Bodhi's student was a jumpy piece named Tam who saw threats everywhere and blocked frantically — plugging every pair of enemy stones, running himself ragged, never building anything of his own.

"You just spent your turn blocking that pair," Bodhi said. "Could they actually have closed that mill this turn?" Tam looked. "...No. The point they need is behind one of their own stones. They can't reach it." "So you blocked a mill that couldn't happen, and wasted a turn you could've used to build. Watch." Bodhi ignored two harmless almost-mills — coolly, on purpose — and used those turns to grow his own line. Then, when the enemy set up a threat that was truly about to close, and would truly hurt, he blocked that one, and only that one, dropping his stone in the gap a heartbeat before they reached it. "See? I let the phantoms go. I stopped the real one. And because I didn't waste turns on the fakes, I had a mill of my own half-built the whole time."

Tam stopped plugging every hole. He learned to ask, coolly, can they close it, now, and would it hurt? — and to block only then. His frantic all-defense turned into calm, chosen defense, with a growing line of his own besides.

"I don't have to stop everything," Tam breathed, almost relieved.

"You just have to stop the right thing," said Bodhi. "The rest is noise."
