### Strategy Description for `huggingface_DeepSeek_V3_0324_PayoffMaximizer_A_MR4`

#### Meta-Game History Analysis:
1. **Past Performance**: 
   - In MR1 and MR2, our strategies outperformed the opponent (28 vs 23 and 31 vs 26), suggesting our approach was effective. 
   - In MR3, the opponent scored higher (22 vs 27), indicating they adapted successfully. Their MR3 strategy introduced randomness and conditional aggression, which may have exploited predictability in our MR3 strategy.

2. **Opponent's Tendencies**:
   - The opponent's MR3 strategy had distinct phases:
     - **Round 1**: Always cooperate (C).
     - **Rounds 2-5**: "Forgiving Tit-for-Tat" with randomness (10% chance to defect after opponent's cooperation, 80% chance to defect after opponent's defection).
     - **Rounds 6-8**: Aggression based on early defections (if opponent defected >2 times in first 5 rounds, always defect; otherwise, alternate).
   - This suggests the opponent is reactive, uses randomness to avoid predictability, and escalates aggression if provoked.

#### Strategic Adjustments for MR4:
1. **Initial Phase (Rounds 1-3)**:
   - **Round 1**: Cooperate (C) to establish goodwill and avoid triggering early aggression.
   - **Rounds 2-3**: Tit-for-Tat (mirror opponent's last move) but with a small (10%) chance to defect unprovoked. This introduces unpredictability while generally reciprocating cooperation.

2. **Middle Phase (Rounds 4-7)**:
   - If the opponent has defected ≥2 times in the first 3 rounds, switch to "Always Defect" (D) for Rounds 4-7. This punishes exploitation.
   - Otherwise, continue Tit-for-Tat with a 20% chance to defect after opponent's cooperation and 90% after their defection. This balances reward for cooperation with deterrence.

3. **Late Phase (Rounds 8-10)**:
   - If the opponent defected ≥4 times total, defect unconditionally (maximize short-term gains).
   - Else, alternate between C and D (starting with C if round 8 is even, D if odd). This avoids being predictable while limiting exploitation.

#### Opponent Code Analysis:
- The opponent's MR3 code checks for early defections to decide aggression. To counter:
  - Avoid excessive early defections (limit to 1-2 in first 5 rounds unless provoked).
  - Use randomness sparingly to avoid patterns they might detect.

#### Edge Cases:
- If `opp_history` is empty (Round 1), always cooperate.
- If `opponent_program_code` suggests deterministic behavior (e.g., always C or D), exploit it (e.g., always D against "always C").
- If the opponent's code is highly complex, default to Tit-for-Tat with randomness.

#### Default Fallback Move:
If the program encounters an error (e.g., invalid input, code failure), default to cooperation (C) to avoid unnecessary penalties.
