Greetings,
As promised - or threatened!

- I just wanted to update all on my progress so far with the various offerings.
First off, CBL didn't install - and I can't get it do so.
It keeps hanging whilst attempting to copy a TTF file to the C:\Windows\System32 folder - I can only assume that one of my security applications isn't happy about it attempting to do so.
And I don't particularly feel like hunting it down - if the Light version of CB is having this much difficulty installing, I shudder to think what the full package would do!
Is it really worth going through all that just to play through "playable PDFs"? Surely, someone can develop something suitable to enable other applications to make use of these?
So, I installed SCID - which went without a single hitch.
It seems a powerful program, if one can get used to its various features opening up in their own window, which I don't mind. (As a former programmer, I'm well used to seeing this sort of thing in Open Source/GPL software.)
I also downloaded Crafty and installed it under Winboard, which I also have, along with GNUChess.
Having assured myself that Crafty worked in Winboard and was superior to the latter chess program, I then set it as the primary engine for analysis. The Engine feature is powerful - I left it overnight analysing a position from one of my older games and it had gone down to some twenty-odd moves by morningtime! (On a 600MHz machine I have to add!)
The Tree feature allows you to explore an opening by playing each move - the possible replies diminish until one is following whatever game is left in your database, in which it occurred.
There are a wealth of reports/graphs which can be displayed along with tournament searches (depending on what actual PGNs you have in your database).
Most importantly, it appears to be transpositional - like Chess Assistant (and BookUp) but
not like ChessBase - which in my book is a must!
Having created a few different databases, I've downloaded games, etc., from TWIC and other sites and been able to see how the games developed from the same or similar positions.
One can use Pattern searches to filter (include/exclude) various games based on positions, etc - IQP (various), Rook sacrifices on c3(!), castling (same/opposite sides), etc., with further ways to refine the filter.
A very useful feature for d-pawn and Sicilian players!
The filter then enables you to show any of the filtered games which automatically open at the matching position - IQP, rook sacrifice, etc.
I will have to try BookUp next - it will be interesting to see how well it works in tandem with SCID. Amongst the PGNs I downloaded was various ECO openings, which I want to check/train upon in BookUp.
Thanks again,

Kindest regards,
