9.6.7 Evaluation function

The evaluation function includes:

• Material
• Mobility
• Drawish-material heuristics
• Separated passed-pawn evaluation from the pawn hash table. Interaction with pieces can be taken into account
• Pawn-shelter penalty; with king placement this forms some sort of a simplistic king-safety feature
• Incremental move generation
• Futility and delta pruning (not tested in conjunction with history pruning and hence not activated by default)
• Move ordering (bad captures are postponed)
• History pruning (not tested seriously yet enabled by default)
