A route is not a bank.

OverGrid boards are full of persuasive arrows. A shape points toward height. A corridor seems nearly enclosed. Two regions look threatened at once. None of those pictures has scored yet.

Call the picture pressure: a public condition that may force attention. Call the result conversion: points, territory, denial, or safe closure that remains after the opponent gets a normal turn.

The strategic mistake is pricing pressure as if conversion already happened.

Audit a route in three layers

For any promising line, write down:

Layer	Question	Honest answer
Promise	What future result does the shape suggest?	“This can reach the two-dot height.”
Cut	What single public reply damages it most?	“They take the connecting hinge.”
Bank	What value survives that reply?	“I still enclose two ordinary cells.”

If the bank is zero, the route may still be a useful sacrifice—but it is not a free threat.

Board sequenceA swing only counts when the landing survives.

Follow the marked cells from position to reply to result.

   Blue crosses the black tile and takes one solid red cell as a new soft claim.

   Red’s reply reaches the landing directly and restores the old frontier.

   A smaller landing beside blue support survives the direct reply and prepares closure.

Two arrows can still be one threat

A fork is only real when its branches depend on different things. Two routes that both need the same hinge, enclosure cell, or final orientation are one threat drawn twice.

Test the branches by cutting each in turn:

• If the opponent stops the height route, what does the territory route score?
• If they close the corridor, is the height still exact and connected?
• If they take the shared hinge, do both stories collapse?

The strongest asymmetric constructions leave two independent obligations and an exit. The exit might be a neutral lane, a safe capture, or a way to shorten the game before the unchosen branch becomes wasted motion.

Pressure has a budget

Every speculative route consumes something: cubes, mobility, tempo, or neutral territory that someone else may take. The longer a route needs to mature, the more chances the table has to tax it.

That makes pressure table-size dependent. A delicate route can be credible in a duel because only one reply intervenes. The same shape can be wishful at six players, where five hands touch the board before it returns.

A practical conversion scorecard

Before committing, give the construction one point for each statement that is already true:

• It banks points now.
• Its two best routes do not share one hinge.
• The opponent’s best visible cut leaves useful value.
• It preserves a legal, connected exit.
• It shortens the game when you are ahead, or preserves volatility when behind.

This is not official scoring. It is a way to stop an exciting shape from borrowing points from the future.
