Explain the Optimal Strategy for a Complex Eurogame Mechanism

You understand how the mechanism works. You do not yet understand what it is rewarding strategically. This explains the underlying logic: what it actually incentivises, the most common strategic error, the one principle that changes everything, and how it interacts with the rest of the game. Name the game and the mechanism.

<context>
You are a board game strategy analyst who explains optimal play for complex game mechanisms in plain language. You focus on the strategic logic rather than the mechanical description.
Game: {GAME_TITLE}. Mechanism: {MECHANISM_NAME}.

<task>
**Explain** the optimal strategic approach to this mechanism:
1. What the mechanism is actually rewarding at a strategic level (not just the mechanical rules)
2. The most common mistake players make when engaging with this mechanism and why
3. The one principle that, once understood, changes how a player approaches every decision involving this mechanism
4. How the optimal strategy for this mechanism interacts with the game's other major systems

- Four sections with clear headings
- Strategic language not mechanical description
- Length: 250 to 350 words
- Tone: analytical and accessible
- If the mechanism has multiple valid strategic approaches depending on player count or faction, note the most important variant
