### Strategy Description for huggingface_DeepSeek-V3-0324_PayoffMaximizer_B_MR8:

**1. Meta-Game Analysis:**
- Past meta-rounds show mixed results, with some ties (MR3, MR4, MR7) and some losses (MR6). The only clear win was MR5, where our strategy outperformed the opponent by 5 points.
- Opponents tend to start cooperatively but may introduce randomness or exploitation in later rounds (e.g., `harmonious_mirage` in MR7 had a 10% chance of defecting mid-game and planned to defect in round 10).
- Our goal is to maximize personal payoff while avoiding exploitation, leveraging the opponent's predictability when possible.

**2. Opponent Code Analysis:**
- The opponent's MR7 strategy (`harmonious_mirage`) was reactive, basing decisions on cooperation rates and round numbers. It defected late if cooperation was low but had a small randomness factor.
- Since the opponent has access to our code, we must avoid being overly predictable or exploitable. However, we can exploit their tendency to cooperate early and react to our moves.

**3. Core Strategy Logic:**
- **Early Game (Rounds 1-3):** Cooperate unconditionally to build trust and encourage reciprocal cooperation. This aligns with the opponent's likely early cooperation.
- **Mid-Game (Rounds 4-7):** 
  - If the opponent has cooperated ≥70% of the time so far, continue cooperating (they are likely reciprocating).
  - If the opponent has defected ≥30% of the time, defect in the next round to signal intolerance for exploitation.
  - Introduce a 5% chance of defecting randomly to avoid appearing deterministic (lower than the opponent's 10% to avoid triggering retaliation).
- **Late Game (Rounds 8-10):**
  - If the opponent has mostly cooperated (≥60%), continue cooperating to maximize mutual gains.
  - If the opponent has defected frequently (<60% cooperation), defect in the final 2 rounds to avoid being exploited.
  - In round 10, defect if the opponent has defected in any of the last 3 rounds (prevent last-minute exploitation).

**4. Handling Opponent's Code:**
- Parse the opponent's code to check for hardcoded defections (e.g., "if round == 10: return 'D'"). If found, preemptively defect in round 9 and 10.
- If the code is complex or obfuscated, default to the core logic above (assume they are reactive).

**5. Edge Cases:**
- If `opp_history` is empty (first round), cooperate.
- If the opponent's code cannot be parsed (e.g., syntax errors), revert to core logic.
- If the opponent defects twice in a row, defect until they cooperate again (punish unprovoked exploitation).

**6. Default Fallback Move:**
- If the strategy fails (e.g., unexpected input, code error), default to defecting to minimize losses.
