**Strategy Description for huggingface_DeepSeek_V3_0324_PayoffMaximizer_A_MR8:**

1. **Meta-Game History Analysis:**  
   - In MR7, our strategy outperformed the opponent (31 vs. 21), suggesting that our approach was effective.  
   - The opponent's MR7 strategy was initially cooperative but shifted to tit-for-tat if defections were observed early. They also defected in later rounds if provoked.  
   - Past matches show that mutual cooperation yields high scores (MR6: 30-30), while unprovoked defection can backfire (MR5: 13-18).  

2. **Opponent's Tendencies:**  
   - The opponent starts cooperatively but is sensitive to early defections, mirroring behavior afterward.  
   - They may adapt to our strategy by analyzing our code, so we must avoid predictable exploitation.  

3. **Strategic Approach:**  
   - **Initial Rounds (1-3):**  
     - Start with "C" to encourage cooperation.  
     - If the opponent defects in Round 1, switch to "D" for Round 2 and mirror their last move thereafter (tit-for-tat).  
     - If they cooperate, continue cooperating unless they defect later.  
   - **Middle Rounds (4-7):**  
     - If the opponent has defected at least once, adopt tit-for-tat (mirror their last move).  
     - If they’ve always cooperated, continue cooperating unless they defect, then retaliate immediately.  
   - **Final Rounds (8-10):**  
     - If the opponent has mostly cooperated, maintain cooperation to maximize mutual gains.  
     - If they’ve defected frequently, defect in the last two rounds to avoid being exploited.  

4. **Handling Opponent's Code:**  
   - Scan their code for deterministic patterns (e.g., always starting with "C").  
   - If their code is similar to MR7, assume they’ll mirror our behavior after initial rounds.  

5. **Edge Cases:**  
   - If no history exists (Round 1), cooperate.  
   - If the opponent suddenly defects after long cooperation, retaliate but revert to cooperation if they do.  

**Key Principles:**  
- Prioritize mutual cooperation but retaliate against defection.  
- Avoid unprovoked defection unless in the final rounds against a exploitative opponent.  
- Adapt dynamically based on the opponent’s behavior.
