CentriScid_ID 123456
CentriScid_Version 10
CentriScid_TacticPly 23
CentriScid_TacticSolution Nxf3 ...
CentriScid_OpeningBlunder 7
CentriScid_OpeningBlunderSideToMove black
etc....
So a complete list of needed keys must be defined at an early stage.
And I strongly suggest to use PGN tags for these, if it was not already the
idea (sorry if I did not get it). This system spares parsing time and
searches should be fast enough, without particular indexing.
