### Strategy Description for `huggingface_DeepSeek_V3_0324_PayoffMaximizer_B_MR9`

**Meta-Game Analysis:**
1. **Past Performance:**  
   - In MR4 and MR6, our strategy outperformed the opponent significantly (22 vs 7 and 24 vs 9).  
   - In MR5, the opponent dominated (3 vs 38), suggesting they may have exploited a weakness in our strategy.  
   - MR7 and MR8 were closer (11 vs 16 and 14 vs 9), indicating adaptation from both sides.  
   - The opponent's MR8 strategy involved early cooperation (rounds 1-3) and defection against deterministic strategies ("always cooperate" or "always defect").  

2. **Opponent's Tendencies:**  
   - The opponent checks for deterministic strategies (always cooperate/defect) and defects against them.  
   - They likely start cooperatively but may defect later if they perceive exploitation.  
   - Their strategy is reactive to our moves, so unpredictability could be advantageous.  

**Strategy Logic for MR9:**  
1. **Initial Rounds (1-3):**  
   - **Round 1:** Cooperate ("C") to signal willingness for mutual cooperation.  
   - **Rounds 2-3:** Alternate between "C" and "D" (e.g., "D" in Round 2, "C" in Round 3) to appear non-deterministic while testing the opponent's response.  

2. **Mid-Game (Rounds 4-7):**  
   - If the opponent cooperated in at least 2 of the first 3 rounds, continue with a "tit-for-tat" (TFT) approach: mirror their last move. This rewards cooperation and punishes defection.  
   - If the opponent defected in 2+ of the first 3 rounds, switch to "grim trigger": defect permanently after their first defection.  

3. **Late Game (Rounds 8-10):**  
   - If the opponent has mostly cooperated (≥70% of rounds), continue TFT to maximize mutual gains.  
   - If the opponent has defected frequently (≥50% of rounds), defect in all remaining rounds to minimize losses.  
   - In the final round (Round 10), always defect ("D") to exploit the endgame (no future repercussions).  

4. **Opponent Code Analysis:**  
   - Scan `opponent_program_code` for "always cooperate" or "always defect" strings. If found, defect unconditionally.  
   - Otherwise, assume the opponent is adaptive and proceed with the above logic.  

**Edge Cases:**  
- If `my_history` or `opp_history` is empty (e.g., Round 1), default to "C".  
- If the opponent's code is unreadable or lacks clear patterns, revert to TFT after Round 3.  

**Key Objectives:**  
- Avoid being exploited by deterministic strategies.  
- Adapt to the opponent's behavior: cooperate with cooperators, defect against defectors.  
- Exploit endgame opportunities (e.g., final-round defection).
