Export Pgn

Post by bohemian65 »

How can I export an ebook as many games in a pgn? In earlier versions I use to be able to do this. Also, how can I change the amount of cores I want an analyses engine to use?

Thanks

I can't figure this out or understand it either. I just input close to 40,000 positions into COW over several months, thinking I could easily export them as many games into ChessBase as I have many times in the past, but now this new version has pulled the rug out from under me and I am livid ... WTH?! Anyone have an answer? Why has this feature been removed and how can we get it back?

You can change the engine options under preferences/engines and input commands under startup commands. I use
uci
setoption name Threads value 3
setoption name Hash value 512

The threads line sets the engine to use 3 cores and the hash sets it to use 515 Mb of hash. Change these numbers to suit.

The function to export an ebook (as PGN games made of all possible move orders) will be added back. I didn't know of anyone who was using it outside of folks creating opening books for playing programs. The function was originally made for manufacturers of dedicated chess computers who needed this format to burn the opening books into EPROMs.

The function will likely wait until after the release of the mobile versions, due out soon.

I have never exported multiple games like this. However, it is an intriguing concept and I can see that it could be useful.

Sometimes I play out to a position from a COW file. Then "export line as a game." I then open the PGN file with a text editor, copy the game and paste it into a chess opening forum for discussion. I also copy FEN diagrams and paste them into a blog for discussion.

Another technique is to use "export line as a game" for multiple positions. Then import them all at once to a new COW file. The new COW file is used as a training file, where I use all the training features of COW. I considered various strategies for making a training file in one go, kind of a mass production process, but found those strategies unsatisfactory. The approach described above requires judgment, picking each "optimal" training variation at a time, but that works best for me.

One reason why I have never exported multiple games from COW is that, for me, COW is the final, optimal, destination for chess information. However, I can conceive of someone developing a COW file, and then choosing to exporting it in a single step. The exported PGN could almost be published as a book. It reminds me of publishing a diary or log, developed daily, as a single book.
