Re: Indexing and searching PGN files prior to import

I recently gave the same task to COW Express and COW Professional, but my experiences differed. COW Express has been around awhile, is well polished, and has no rough edges that I have seen. COW Express: I selected my 2018 game file, then requested a search. For my ECO code, I typed c15. This was co...

I just ran across an article on "contempt" in this context. It's a way to maintain more play in the position:

Can you send me a PGN file that you're having trouble with?


When I drag the Fischer file to this box (to add as an enclosure), I get the error: "Invalid file extension: Fischer.pgn"

Is Stockfish 10 64 bit an optimist?

I was analyzing in COW Professional, build 92, with the latest version of SF. In particular, I was looking at the MacCutcheon French with 5Ne2. It may not be the best move, but looks to provide more fluid play than other moves. I followed SF's suggestions for a few moves. When it is white to move, i...

Yes, build 92 solved my problem. I can now click on any candidate move on the list and it plays directly.

So here are a few ideas to consider before a future release. 1) Selecting candidate moves from a list. In the past you could click on any candidate move to make the move. That does not work...

Indexing and searching PGN files prior to import

I was slow to appreciate this feature now I miss it. Background follows. I had Bookup under Mac OS 9 and I did my PGN file game selection in Exachess before importing the selected games into Bookup. COW Express had the ability to search PGN databases. At first I didn't use it (relying on Chess Assis...
