 |
|
When I started using Bookup/COW I generated large e-books containing lots of games. As I gained a little bit more experience I started to realize that this is not the best way how to use this software.
As a beginner I was mostly interested to explore some of the more common openings. Large e-books are not very helpful in this endeavour. It is next to impossible to use EPD on any book that has an excess of positions. Even with a fast computer it takes only a few seconds less than eternity to complete an analysis.
If you restrict your study to small e-books, where the content is confined to one particular opening, you will have a much better chance to explore this opening in its full depth.
I recently purchased the Albin CounterGambit e-book, mainly because it become available at a bargain price. This provided me with a good example to test my own way to explore this opening.
Here is a screenshot of a comparison between my own e-book and the purchased one.
From this you might see the superiority (forgive my subjective back slapping) of my e-book (The one on the left side).
Notice that it contains the 4.Ne2 and 4.d5 candidate moves that are absent from the purchased e-book.
It took me only a relatively short time to produce and provides a much better move guide. I used the Rybka3 engine and the Bookup/COW feature to import engine execution lines to generate most of my lines. At strategic points I let the engine run for a while (good time to go on an extended coffee break) and then moved the generated sequence into my e-book. This is equivalent to have a super GM helping me. This of course is the main reason why my book is that much better !

There are lots of good ways to develop our repertoires. This works for John and probably many others. I just want to point out to the less experienced that keeping openings in different ebooks prevents COW from finding transpositions among them.
Also, note that purchased opening books usually have their moves color coded. Note the green color codes in the right-side ebook. If they are not color coded you can color code them all at once yourself in just a couple of steps. I mention this because you can import the new ebook into your established ebook and the new moves will be color coded. No need to have them open side by side. If you're not sure about importing the new book into your established repertoire then rename the books so as to create a second working ebook, etc.
These are alternatives for the less experienced. John's process works well for him and many others.

I am delighted to see this discussion underway.
I have my "Moderator's Hat" on, and need to say that our Bulletin Board is tending to anarchy because Topics are being discussed in the wrong Forums.
When a Topic like "Opening Study" is initiated, the initiator has the option of which Forum should contain the Topic. Think of the "Forum" as a container for the "Topic".
The "Container" concept extends further. Our Bulletin Board has "Categories" that contain "Forums".
This new Topic "Opening Study" is currently contained in the "News Forum" which in turn is contained in the "General Category".
Considering that we have a "Chess Openings Forum" in our "Chess Talk Category", I am considering my Moderator responsibility and thinking that we would move away from tending to anarchy if I relocated this new Topic. The location mentioned here seems like a logical home.
Since 2 members have already Posted to this Topic, I have a concern about stepping on toes if I just undertake this without a discussion period. I am also open to suggestions about a more suitable location (among the Categories and Forums that we already have) than the one I suggest, but this Topic does not belong in our "News Forum".
I invite discussion on this issue, but intend to undertake some relocation of this new Topic tomorrow.
There are similar issues with Topic placement that I will be evaluating, and it is likely that I will just make a judgement call and take action without discussion in most of those instances. Members may observe that some Topics are split. Forum Moderators are tasked with the responsibility of imposing some order on chaos, and my motivation here is meeting that responsibility

I see what you mean. Please feel free to move posts or edit topic names of any of my posts, past, present, or future.

Thanks Ken.
May I add a subject to a Post where the "Post Subject" field is blank?
I think the forum software provides some automation in this regard, i.e. when quoting to initiate a reply there is an RE: inserted before the subject of the Post being quoted, and this automates assurance of some referencing value being placed in the "Post Subject" field. When the "Post Subject" field is blank, this does not work.
I am speaking from memory, and may discover that this remark is not entirely accurate. However, it would not be a bad thing if it did work that way.

Note to the Sys Admin
Your suggestion to move the topic is very approbriate. I just did not know what a good place would be.
You might notice that I edidted my post to reduce the size of my insert. I did not realize that the width would dictate all the following text and also all the follow up posts. Interesting lesson !

My post was trying to point out that one could generate an e-book from scratch, that is at least as good as the commercial version, by employing Bookup/COW technology without the need of any game base. It was only for this reason that I showed them side by side. Yes, I could have easily imported the e-book and than worked from there.
Once you used the engines move lines extensively in the early part of the e-book, you will find all kinds of transitions as well. It will be up to you to follw these transition to other openings or not. I stick to the lines that my e-book opening is devoted to, to avoid a dilution of the basic concept.
The particular e-book that I used for this purpose would not be worth the few bucks I spent for it, if for any other reason than to demonstrate this capability.

John, how does this "import engine execution lines" feature of Bookup/COW work? I couldn't find it in any of the Bookup/COW menus or in the help files... Regards, Geoff |

I hope the image will show you how it is done.
If you still need more info just say so.

Further to my previous post:
Make sure you have selected Always Solve in the Preference-General pulldown.
Before executing the move sequence note the assessment value displayed in the engine pane and add this assessment at last move of the execution line.
You do this via the edit pulldown Change Assessment
Negative values are entered by first clicking on the down arrow.

John, thank you for the quick and helpful response! This feature is quite useful, now I just have to figure out the best way to import engine analysis from ChessBase/Fritz. What I do currently is export a bookup line as a game, load the game into CB or Fritz, turn on the engine, bump the number of simultaneous variations to 5 or more, and then after reaching 20-ply of analysis depth I right-click the engine window and pick "copy all to notation." I then save the annotated game and then import it back into Bookup. The CB/Fritz evaluations for the final node of each variation calculated are preserved in the comments window for that node but I have to use bookup/COW's "edit assessment" function to enter the evaluation into the assessment window. Just for fun I usually let Bookup/COW's Crafty engine evaluate the leaf nodes for a few hundred million moves to see how Crafty's assessment accords with CB/Fritz's. Regards, Geoff |
