### Strategy Description for huggingface_DeepSeek-V3-0324_PayoffMaximizer_B_MR2:

**1. Meta-Game Analysis:**
- In Meta-Round 1, both players used `friendly_neighbor`, resulting in mutual cooperation and equal payoffs (20 each). This suggests that the opponent may initially favor cooperation but is capable of adapting to exploit naive strategies.
- The opponent's `friendly_neighbor` strategy from MR1 shows they analyze the opponent's code for simple patterns (e.g., "always cooperate" or "always defect") and adjust accordingly. They default to cooperation early but may defect if they detect exploitable behavior.

**2. Opponent Code Analysis:**
- The opponent's strategy is reactive and attempts to exploit simple deterministic strategies. They likely expect us to either:
  - Continue cooperating (risking exploitation if they defect).
  - Attempt to defect early (which they may punish).
- Their strategy may not handle sophisticated conditional logic well, especially if we introduce unpredictability.

**3. Core Strategy Logic:**
- **Initial Phase (Rounds 1-3):** Cooperate ("C") to establish goodwill and avoid triggering immediate retaliation. This builds trust and allows observation of the opponent's behavior.
- **Middle Phase (Rounds 4-7):** Introduce controlled unpredictability:
  - If the opponent has cooperated in all previous rounds, continue cooperating with a 70% probability and defect with 30% probability (to test their responsiveness).
  - If the opponent has defected even once, mirror their last move (tit-for-tat) to prevent exploitation.
- **Late Phase (Rounds 8-10):** Shift toward maximizing payoff:
  - If the opponent has mostly cooperated (≥70% of rounds), defect in the last 2 rounds to exploit their trust.
  - If the opponent has defected frequently (≥30% of rounds), continue mirroring their last move to minimize losses.
- **Code Analysis:** Scan `opponent_program_code` for keywords like "always cooperate" or "always defect". If found, defect immediately (exploiting their rigidity). Otherwise, proceed with the phased approach above.

**4. Edge Cases:**
- If `opp_history` is empty (first round), cooperate.
- If `opponent_program_code` is unreadable or contains errors, default to the phased strategy.
- If the opponent starts defecting early, switch to tit-for-tat immediately.

**5. Rationale:**
- Early cooperation avoids early mutual defection traps.
- Controlled unpredictability prevents the opponent from exploiting a fixed pattern.
- Late-game exploitation maximizes payoff if the opponent remains cooperative.
- Mirroring defends against exploitation while maintaining reciprocity.
