### Strategy Description for 'huggingface_DeepSeek-V3-0324_PayoffMaximizer_A_MR4':

**1. Meta-Game Analysis and Adaptation:**
- In Meta-Round 3, the opponent's strategy (`sunshine_ally`) was highly cooperative but punished defections aggressively (e.g., after 3 consecutive defections). It also checked for always-defectors in the opponent's code. This suggests the opponent is willing to cooperate but will retaliate if exploited.
- Our past strategies (`friendly_neighbor`, `sunshine_optimist`, `harmonious_illusionist`) were overly cooperative, leading to suboptimal payoffs (e.g., MR3 where we scored 10 vs. the opponent's 20). We need a more balanced approach that maximizes our payoff while avoiding triggering the opponent's retaliation.

**2. Core Strategy Logic:**
- **Initial Phase (Rounds 1-3):** Cooperate to build trust and avoid triggering the opponent's defection checks. This mirrors the opponent's behavior and establishes a cooperative baseline.
- **Middle Phase (Rounds 4-7):** Introduce *opportunistic defections*:
  - Defect *sporadically* (e.g., every other round) to exploit the opponent's cooperation, but avoid 3+ consecutive defections to prevent triggering their retaliation.
  - If the opponent defects unexpectedly, respond with a *tit-for-tat* (match their last move) in the next round to signal we won't tolerate exploitation.
- **Final Phase (Rounds 8-10):** Shift toward defection if the opponent remains cooperative, as late-game defections are less likely to be punished in future rounds. However:
  - If the opponent starts defecting frequently, revert to tit-for-tat to minimize losses.
  - If the opponent's code suggests they defect late (e.g., "return 'D'" in later rounds), preemptively defect.

**3. Opponent Code Analysis:**
- Scan `opponent_program_code` for patterns like "return 'D'" or hardcoded defection logic. If detected, defect preemptively from Round 1.
- If the opponent's code is similar to `sunshine_ally`, follow the phased strategy above to exploit their cooperative tendencies without triggering retaliation.

**4. Edge Cases:**
- If the opponent always cooperates (e.g., "return 'C'"), defect from Round 6 onward.
- If the opponent is random or unpredictable, default to tit-for-tat after Round 3.
- If `opp_history` is empty (Round 1), always cooperate initially.

**5. Key Principles:**
- Avoid *systematic* defection to prevent retaliation.
- Exploit cooperative opponents *late* in the match.
- Use tit-for-tat only as a defensive measure, not as a primary strategy.

*(Rationale: Defection is the safer fallback to avoid being exploited if the strategy fails.)*
