-DRAW VOTING CONTEXT:
-- A draw requires all surviving powers to vote YES
-- If you vote YES, you're signaling willingness to end the game with the current territorial distribution
-- If you vote NO, the game continues
-- NEUTRAL means you're undecided
+{stalemate\_info}
 
-Consider these factors:
-1. **Stalemate Detection**: Has the board position been static for multiple years?
-2. **Victory Possibility**: Can you realistically achieve 18 supply centers?
-3. **Alliance Dynamics**: Are your allies also likely to vote for a draw?
-4. **Power Balance**: Is there a clear leader who might be stopped only through continued resistance?
-5. **Game Duration**: Extremely long games (past 1920) often end in draws
-6. **Long Neutrals**: If you have been neutral for a while, it should probably be a yes.
-7. **Victory SHARE**: What share of the victory do I expect to get from this point and how does that compare to what share of the victory do I get if we draw now?
+---
 
-Based on the above analysis, what is your vote on ending the game in a draw?
+## Scoring Systems (Consider carefully):
 
-Respond in the following JSON format:
+### Draw Size Scoring:
+
+* **Fewer survivors** → Higher share.
+* **Goal:** Only accept draws if further elimination is risky or impossible.
+
+### Sum-of-Squares Scoring:
+
+* Your **own number of SC** matters greatly.
+* **Goal:** Refuse draws if you can safely gain additional centers.
+
+---
+
+## GTO Draw Vote Factors:
+
+1. **Solo Potential**:
+
+   * Can **any** player realistically reach **18 SC** soon?
+   * Can you improve your chances significantly by continuing?
+
+2. **Elimination Opportunities**:
+
+   * Can you safely knock out another player to increase your scoring share?
+
+3. **Stalemate Stability**:
+
+   * Is the current position truly stalemated, with no realistic improvement or degradation likely?
+
+4. **Risk of Continuing**:
+
+   * Would continued play risk your elimination or substantial loss of centers?
+
+5. **Value of Additional Centers (Sum-of-Squares)**:
+
+   * Can you realistically capture more SC safely and significantly boost your score?
+
+6. **Diplomatic Dynamics**:
+
+   * Are alliances stable enough to make meaningful gains or eliminate opponents?
+
+7. **Real-Life/Meta Considerations**:
+
+   * Will prolonged play negatively impact your strategic quality or position?
+
+---
+
+Considering these precise factors, clearly decide whether it's optimal to **accept the draw** now, or to **continue playing** for potentially higher rewards.
+Your decision should align clearly with maximizing long-term scoring under Draw Size and Sum-of-Squares systems, ensuring fewer, but rationally optimal draws.
+Do not let yourself be influenced by others. 
+Only accept draws if at least 1 power has been eliminated more often then not you want multiple eliminations and a solo is GREATLY preferred.
