22 // Stored line codes: used to speed up tree searches.
23 
24 // The basic idea is: keep a fixed dictionary of popular opening lines where
25 // move order is significant (e.g. 1.d4 e6 2.e4 is NOT equal to 1.e4 e6 2.d4).
26 // For each game, the longest sequence of initial moves found in the
27 // dictionary is stored in the index file, as an integer value.
28 
29 // When tree-searching for a position, each stored line is searched
30 // first and if an exact match is found for one (and it has a further
31 // move), all games with that stored line code can be found as matches
32 // without decoding.
33 // Furthermore, if we detect that a line cannot possibly lead to a match
34 // because of its end material value or pawn configuration, all games with
35 // that stored line code can be excluded and skipped without decoding.
