OpenFront Nation Pressure

Against a Hard or Impossible Nation, expand only while the next capture improves your position without turning you into its best safe prize. Keep one defensible contact, let the Nation spend elsewhere, then use a bounded attack that leaves a declared reserve. Stop when your troop count drops, valuable structures become exposed, or a second hostile border opens.

This guide covers the v34 juicy target strategy, verified against v0.34.0-beta1.

The Juicy Target Strategy in v34

Hard and Impossible Nations now actively hunt valuable bordering rivals they can safely beat using the juicy() strategy. A candidate must have current Troops no greater than 75% of the Nation’s current Troops (Hard) or 90% (Impossible).

Among eligible targets, the Nation scores on three equally weighted signals:

1. Structure levels (Cities, Factories, Ports — excluding Defense Posts and Missile Silos)
2. Unused troop-cap headroom (1 - current Troops / maximum Troops)
3. Owned tiles

A richer, underfilled player can outrank a numerically weaker neighbor.

The P-R-E-S-S Framework

P - Pressure: Can the Nation send a meaningful force now?

Record visible current Troops, whether it is refilling or already sending attacks, whether free land touches it, and whether another player is hitting it. Hard evaluates every 45-59 ticks; Impossible every 30-49 ticks.

R - Reward: Do structures, headroom, and land raise your value?

Count your capturable structure levels. Estimate how underfilled you are compared with your own maximum. Compare your land with other eligible neighbors.

E - Exposure: Which new borders can punish the capture?

List direct hostile contacts after the proposed capture, a water route that can bypass the line, and any ally whose expiry would expose a side.

S - Stop line: What visible event ends the push?

Useful examples: “stop when 650,000 Troops remain,” “stop after the western neutral pocket closes,” “stop if the Nation ends its other attack.”

S - Switch: Refill, fortify, reroute, negotiate, or counter?

Understanding Nation Behavior

Hard and Impossible Nations also no longer ignore their troop cap when attacking neutral land or fallout. The FFA strongest-neighbor reserve floor (75% Hard, 90% Impossible) and the 20% minimum-send check remain active but are bypassed in Team mode.

A Nation below its generated 30%-39% reserve waits. One below its 50%-59% trigger usually waits but retains a one-in-ten continuation chance.

Classifying Border State

Cold: Nation lacks reserve, has attractive neutral land, or is committed elsewhere. A cold border permits a probe.

Warm: You are eligible and your border value is rising. A warm border requires an explicit stop line.

Hot: You are eligible, underfilled, structure-rich, and the Nation has both Troops and a clean contact. A hot border should be shortened or allowed to cool.

Common Failure Modes

“Stay above 75% and I am safe” — Wrong. The line belongs only to juicy, moves with Nation Troops, and other branches remain. Track commitment, relation, cap fill, and border geometry.

“The weakest neighbor goes first” — Wrong. Valuable land, structure levels, and headroom can outrank raw current Troops.

“Provoke a small counterattack” — Dangerous. Retaliation and Team exceptions can bypass ordinary restraints.

“More border means more options” — Wrong. New contact may expose the economic core and add a second attacker.

Mode Adjustments

FFA: The 75% Hard and 90% Impossible reserve floors plus the 20% minimum-send check create readable constraints. Read the floor as a reason to recalculate after a major battle.

Team: Remove FFA assumptions. Weak attacks can proceed and the neighbor-based troop floor does not apply. Coordinate stop lines with teammates.

Humans vs Nations: Draw one P-R-E-S-S row per contact. Collapse the front one Nation at a time when possible.

A Three-Line Pressure Ledger

Before expansion: Nation Troops, your Troops/cap, prize levels, borders, intended stop.

After first contact: Eligibility estimate, new route, new neighbors, current pressure.

After Nation commitment: Target, visible force, remaining route, counter objective.
