**Strategy Description for huggingface_DeepSeek-V3-0324_PayoffMaximizer_B_MR5:**

1. **Meta-Game History Analysis:**
   - Past strategies have shown mixed results, with some rounds ending in mutual cooperation (MR2, MR3, MR4) and others favoring the opponent (MR1). The opponent's strategies tend to exploit unconditional cooperators ("always C") but also retaliate against defections. 
   - The opponent's previous strategy (`shadow_dancer`) is conditional: it starts cooperatively but defects in later rounds or if it detects aggression (e.g., multiple recent defections). It also exploits "always C" or "always D" strategies.

2. **Opponent Code Analysis:**
   - The opponent checks for deterministic strategies (always C/D) and defects against them. It also defects in later rounds (≥8) or after observing defections. This suggests it values long-term cooperation but is wary of exploitation.
   - Key takeaway: The opponent is adaptive but not purely vengeful; it rewards cooperation but punishes defection.

3. **Strategic Approach:**
   - **Initial Phase (Rounds 1-3):** Cooperate unconditionally to establish trust and avoid triggering the opponent's defection conditions. This mirrors the opponent's initial cooperation in `shadow_dancer`.
   - **Middle Phase (Rounds 4-7):** 
     - If the opponent has cooperated consistently (no defections), continue cooperating to maximize mutual gains.
     - If the opponent has defected even once, switch to "tit-for-tat" (mirror their last move) to prevent exploitation while leaving room for reconciliation.
   - **Late Phase (Rounds 8-10):** 
     - Defect in Round 8 regardless of history to exploit the opponent's tendency to defect late (as seen in `shadow_dancer`). 
     - For Rounds 9-10, revert to tit-for-tat to avoid unnecessary retaliation if the opponent resumes cooperation.
   - **Code Analysis:** Scan `opponent_program_code` for unconditional moves ("always C/D"). If detected, defect immediately (exploiting their predictability). Otherwise, proceed with the phased strategy above.

4. **Edge Cases:**
   - If the opponent's code is unreadable or lacks clear patterns, default to tit-for-tat after Round 3.
   - If the opponent defects early (Round 1-3), assume they are testing limits and respond with tit-for-tat starting Round 4.

5. **Objective Alignment:**
   - This strategy balances cooperation (to maximize mutual payoffs) with calculated defection (to exploit late-round weaknesses). It adapts to the opponent's behavior while prioritizing long-term cumulative payoff.
