═══════════════════════════════════════════════════════════════════════════════ ♟ CHESS ENGINE IMPLEMENTATION ═══════════════════════════════════════════════════════════════════════════════

BOARD REPRESENTATION: • 8x8 Grid using Position(row, col) • Rows: 0-7 (top to bottom, black at top) • Cols: 0-7 (left to right, a-h) • Dictionary mapping Position → Optional[Piece] • Efficient lookup and move validation

MOVE GENERATION:

  1. PAWN MOVES: ├─ Forward: 1 square (2 on first move) ├─ Direction: -1 for black, +1 for white ├─ Capture: 1 square diagonally forward └─ Promotion: At row 0 (black) or row 7 (white)

  2. KNIGHT MOVES: ├─ Pattern: 8 L-shaped moves (2+1 or 1+2 squares) ├─ Can jump over pieces └─ Validated against board boundaries

  3. BISHOP MOVES: ├─ Diagonal rays in 4 directions ├─ Sliding until blocked └─ Can capture opponent piece only

  4. ROOK MOVES: ├─ Orthogonal rays in 4 directions (horizontal/vertical) ├─ Sliding until blocked └─ Can capture opponent piece only

  5. QUEEN MOVES: ├─ Combination of bishop (4 diagonals) and rook (4 orthogonal) ├─ 8 directions total └─ Most powerful piece

  6. KING MOVES: ├─ 1 square in any of 8 directions ├─ Cannot move into check (simplified) └─ Game ends if checkmated

MOVE VALIDATION: ✓ Destination must be on board ✓ Destination empty OR occupied by opponent piece ✓ Piece type movement rules must be followed ✓ Cannot move off board or through pieces (except knight)

SPECIAL MOVES NOT IMPLEMENTED: • Castling (king-rook simultaneous move) • En passant (special pawn capture) • Pawn promotion (promotion handled as simple arrival) • Check/Checkmate detection (simplified)

═══════════════════════════════════════════════════════════════════════════════ 🤖 AI OPPONENT SYSTEM ═══════════════════════════════════════════════════════════════════════════════

AI DECISION MAKING:

Skill-Based Heuristic:

┌─ Skill 1-3: Random moves (mostly meaningless) ├─ Skill 4-5: Random with 30% tactical captures ├─ Skill 6-7: Random with 60% tactical captures ├─ Skill 8-9: Weighted strategy (capture valuable pieces) └─ Skill 10: Full evaluation (piece value heuristic)

PIECE VALUE EVALUATION: Pawn = 1 point Knight = 3 points Bishop = 3 points Rook = 5 points Queen = 9 points King = 100 points (never captured)

MOVE SELECTION ALGORITHM:

For each valid move:

  1. Evaluate capture value (if any)
  2. Score = capture_value × (skill_level / 10)
  3. Add randomness factor (skill_level <= 7 only)
  4. Select move with highest score

THINKING TIME: • Simulated delay: 0.5 + random(0-1.0) seconds • Creates illusion of AI thinking • Improves user experience • Makes game feel less instant

AI LIMITATIONS (Intentional): • No look-ahead (doesn't plan multi-move sequences) • No threat assessment (doesn't see own piece danger) • No position evaluation (only captures matter at skill 10) • No endgame knowledge • Makes mistakes at lower skill levels (by design)
