### Strategy Description for `huggingface_DeepSeek_V3_0324_PayoffMaximizer_B_MR5`:

1. **Meta-Game History Analysis**:
   - In MR1, our strategy outperformed the opponent (16 vs. 11), suggesting an effective initial approach.
   - MR2 resulted in a tie (20 vs. 20), indicating the opponent adapted to our strategy.
   - MR3 saw the opponent outperforming us (11 vs. 16), likely due to their adaptation.
   - MR4 was a strong win for us (22 vs. 7), suggesting our strategy successfully exploited their predictability.

2. **Opponent's Previous Code Analysis**:
   - The opponent's MR4 strategy started with cooperation ("C") and checked for deterministic strategies (always cooperate/defect). It defected if the opponent always defected but had incomplete logic for always-cooperate opponents.
   - This suggests the opponent is cautious but may have exploitable gaps in their logic, especially against non-deterministic strategies.

3. **Strategy Logic for IPD Match**:
   - **Initial Move**: Start with "C" to signal willingness to cooperate, as this can encourage mutual cooperation in early rounds.
   - **Opponent Code Inspection**: 
     - If the opponent's code is deterministic (always "C" or "D"), exploit it immediately:
       - If they always cooperate ("always cooperate" or "return 'C'" in their code), defect ("D") from round 2 onward to maximize payoff.
       - If they always defect ("always defect" or "return 'D'" in their code), defect ("D") from round 1 onward to minimize losses.
     - If the opponent's code is non-deterministic (like ours), proceed with a tit-for-tat (TFT) variant:
       - Mirror the opponent's last move (TFT) but with a forgiveness mechanism: after two consecutive defections from them, cooperate ("C") once to test for reconciliation.
   - **Late-Game Adjustment**: In the last 2 rounds (rounds 9-10), defect ("D") unconditionally to prevent exploitation by the opponent's endgame defection. This is safe because there’s no future retaliation possible.
   - **History Tracking**: Use `my_history` and `opp_history` to track patterns. If the opponent defects more than twice in the first 5 rounds, switch to "D" for the remainder of the match (assuming they are aggressive).

4. **Edge Cases**:
   - If the opponent's code is unreadable or fails to execute, default to TFT with forgiveness (as above).
   - If the match history is empty (round 1), always start with "C".

5. **Key Objectives**:
   - Maximize payoff by exploiting deterministic opponents.
   - Encourage mutual cooperation with non-deterministic opponents while protecting against exploitation.
   - Secure endgame advantages by defecting in the final rounds.
