Evaluation

The evaluation function determines how good or bad a position is for each side. Key evaluation aspects include:

  • Material Balance

  • Mobility

  • King Safety

  • King Distance

  • Tempo

  • Check Tempo

  • Winnable

  • Can Passer Pawn Move

  • King Distance

  • Rook Open File

  • Rook Semi Open File

  • Pawn Structure

    Key Factors in Pawn Structure:

    • Passed Pawns
    • Isolated Pawns 🚧
    • Doubled Pawns 🚧
    • Backward Pawns 🚧
    • Pawn Chains 🚧

  • Tapered Eval (Opening, Middlegame, Endgame)

Search

The search function explores possible moves and evaluates their outcomes to find the best one. Core techniques include:

  • Negamax with Fail-Hard Framework

  • Principle Variation Search

  • Iterative Deepening

  • Transposition Table (TT)

  • Aspiration Windows

  • Late Move Pruning

  • Mate Distance Pruning

  • Late Move Reduction

  • Null Move Pruning

  • Futility Pruning

  • Reverse Futility Pruning

  • Quiescence SEE Pruning

  • PVS SEE Pruning

  • Improving Heuristic

  • Razoring

  • Cut Node

  • Quiescence Search

  • Move Ordering

    Priorities in Move Ordering:

    When searching for the best move, the engine searches moves in the following order:

    1. Transposition Table Move
    2. Principle Variation Moves
    3. SEE Move Ordering (Capture Moves)
    4. MVV/LVA (Capture Moves)
    5. Quiet History Moves

Time Control

  • Hard Limit
  • Soft Limit
  • Best Move TM
  • Evaluation TM
