### Strategy Description for `huggingface_DeepSeek_V3_0324_PayoffMaximizer_A_MR9`

#### Meta-Game Analysis:
1. **Past Performance**: 
   - In MR4 and MR6, mutual cooperation led to equal high scores (25 and 30 respectively).
   - In MR5, our strategy underperformed (13 vs 18), suggesting the opponent exploited us.
   - In MR7, we outperformed the opponent (31 vs 21), likely by defecting strategically.
   - In MR8, the opponent outperformed us (24 vs 34), indicating they adapted to our strategy.

2. **Opponent's Tendencies**:
   - The opponent's MR8 code shows they:
     - Start with cooperation ("C").
     - Check if our strategy is always "C" or "D" and react accordingly.
     - Defect in later rounds (round 9+).
     - Punish defection (if we defect, they may retaliate).
   - They seem to be adaptive and willing to defect if they detect weakness or predictability.

#### Strategy Logic:
1. **Initial Move**: 
   - Start with "C" to signal willingness to cooperate, as this has historically led to high mutual payoffs (MR4, MR6).

2. **Opponent Code Analysis**:
   - Parse `opponent_program_code` to detect if they are:
     - Always "C" or "D": If so, defect immediately (exploit unconditional cooperators, avoid unconditional defectors).
     - Tit-for-Tat (TFT) or similar: Mirror their last move to maintain mutual cooperation or avoid exploitation.
     - Adaptive like MR8: Be cautious and defect in later rounds to avoid being exploited.

3. **Mid-Game Play**:
   - If the opponent has defected in the last 2 rounds, switch to "D" for the rest of the match (punish exploitation).
   - If the opponent has cooperated consistently, continue cooperating unless nearing the end (rounds 8+).

4. **End-Game Play**:
   - From round 8 onward, defect unconditionally to maximize payoff in the final rounds (opponent's MR8 strategy does this too).
   - This prevents the opponent from defecting first in the endgame.

5. **Edge Cases**:
   - If `opp_history` is empty (first round), cooperate.
   - If `opponent_program_code` cannot be parsed or is unclear, default to Tit-for-Tat (mirror last move).

#### Key Principles:
- **Early Cooperation**: Start cooperatively to build trust.
- **Adapt to Opponent**: Use their code and history to decide whether to cooperate or defect.
- **Retaliate if Exploited**: If the opponent defects repeatedly, switch to defection.
- **Endgame Exploitation**: Defect in later rounds to maximize payoff.
