PINE LIBRARY
업데이트됨 Public_Library_ChessBook
This library holds the opening book for the Chess script. It lives apart from the brain (ChessAI) so the openings can grow without republishing the logic. It imports nothing and contains no logic of its own beyond building the map.
Each entry pairs the moves played so far (both sides' moves, lowercase, one space between) with our reply, written the same way - so the key "e2e4 e7e5" answers with "g1f3". Some entries offer several replies separated by "|", and the consumer picks between them with its game seed, so back-to-back games can open differently. The empty-string key holds White's very first move.
We use a map because the book question is exactly a lookup: given the moves played so far, what do we reply? Simply query the canonical move string as the map key and if we get a reply that's our move in response.
Pine maps can't hold arrays as values, which is why several replies pack into one "|"-separated string. Of course we could define a UDT that contains an array, but it's overhead. The trade-off of keying by move sequence rather than by position is that an unusual move order into a known position misses the book - the cost is an early exit to the ladder, never a wrong move, and in exchange every entry in the source reads as a real game you can play through.
The book holds enough entries for every common defence and sideline on both sides, deeper main lines, and wider choices in some of them.
This split of data from calculation is worth using for non-chess scripts: when a big lookup table and the logic that reads it live in separate libraries, the table can grow on its own release schedule.
