Type-synonyms

type Transformation positionHash = DynamicMoveData positionHash -> DynamicMoveData positionHash

The type of a function which transforms the dynamic move-data.

Data-types

data KillerMoveKey

• Killer-moves are indexed by both the move & the rank of the piece which made it.
• CAVEAT: there's still ambiguity in this key, since it may match either a different piece of the same rank or have a different move-type (though typically only quiet moves are recorded), in sibling games.
