ChessX supports Polyglot (.bin), Arena (.abk) and ChessBase (.ctg) opening books and I can open all 3 just fine in the Database and Opening Tree windows.
However, when I play against an engine, only bin and ctg books appear in the book selector dropdown. Even though, I have my abk book opened in the Opening Tree window, I cannot choose it in the analysis window.
Does that mean you cannot use abk books when playing games? or is this a bug?
Thanks!
