General Guidelines

Some Basics
1. Under Board "Frequently Asked Questions" (FAQs) there are 3 sections dealing with General Forum Usage, User Profile Features, and Reading and Posting Messages. These deal with everything from Avatars to Your Notifications. Most general technical questions are covered there. Here is a link to the FAQs. https://forum.chesstalk.com/help
2. Consider using the SEARCH button if you are looking for information. You may find your question has already been answered in a previous thread.
3. If you've looked for an answer to a question, and not found one, then you should consider asking your question in a new thread. For example, there have already been questions and discussion regarding: how to do chess diagrams (FENs); crosstables that line up properly; and the numerous little “glitches” that every new site will have.
4. Read pinned or sticky threads, like this one, if they look important. This applies especially to newcomers.
5. Read the thread you're posting in before you post. There are a variety of ways to look at a thread. These are covered under “Display Modes”.
6. Thread titles: please provide some details in your thread title. This is useful for a number of reasons. It helps ChessTalk members to quickly skim the threads. It prevents duplication of threads. And so on.
7. Unnecessary thread proliferation (e.g., deliberately creating a new thread that duplicates existing discussion) is discouraged. Look to see if a thread on your topic may have already been started and, if so, consider adding your contribution to the pre-existing thread. However, starting new threads to explore side-issues that are not relevant to the original subject is strongly encouraged. A single thread on the Canadian Open, with hundreds of posts on multiple sub-topics, is no better than a dozen threads on the Open covering only a few topics. Use your good judgment when starting a new thread.
8. If and/or when sub-forums are created, please make sure to create threads in the proper place.
Debate
9. Give an opinion and back it up with a reason. Throwaway comments such as "Game X pwnz because my friend and I think so!" could be considered pointless at best, and inflammatory at worst.
10. Try to give your own opinions, not simply those copied and pasted from reviews or opinions of your friends.
Unacceptable behavior and warnings
11. In registering here at ChessTalk please note that the same or similar rules apply here as applied at the previous Boardhost message board. In particular, the following content is not permitted to appear in any messages:
* Racism
* Hatred
* Harassment
* Adult content
* Obscene material
* Nudity or pornography
* Material that infringes intellectual property or other proprietary rights of any party
* Material the posting of which is tortious or violates a contractual or fiduciary obligation you or we owe to another party
* Piracy, hacking, viruses, worms, or warez
* Spam
* Any illegal content
* unapproved Commercial banner advertisements or revenue-generating links
* Any link to or any images from a site containing any material outlined in these restrictions
* Any material deemed offensive or inappropriate by the Board staff
12. Users are welcome to challenge other points of view and opinions, but should do so respectfully. Personal attacks on others will not be tolerated. Posts and threads with unacceptable content can be closed or deleted altogether. Furthermore, a range of sanctions are possible - from a simple warning to a temporary or even a permanent banning from ChessTalk.
Helping to Moderate
13. 'Report' links (an exclamation mark inside a triangle) can be found in many places throughout the board. These links allow users to alert the board staff to anything which is offensive, objectionable or illegal. Please consider using this feature if the need arises.
Advice for free
14. You should exercise the same caution with Private Messages as you would with any public posting.
I enjoy analyzing pawn endgames more than playing matches. I wanted to find out if anyone here has experience with a program called Freezer which I understand can be used to exhaustively analyze a pawn endgame containing more pawns or pieces than an endgame tablebase can handle. In effect it would create a tablebase for that specific endgame position.
I have become obsessed with Position #135 in Basic Chess Endings (Neustadtl-Porges) which I believe is a draw and have thought about using Freezer or a comparable software to analyze it
Fine says: In No. 135, White wants to occupy the square d4. To do so he must first occupy e4, with the Black king at c5. He has two squares (e3 and f3) from which he can approach e4, while Black has only one. Thus he can reach his goal by 1.Kf3 Kc6 2.Ke2 Kc5 3.Kf2 Kc6 4.Kf3 Kd5 5.Ke3 Kc5 6.Ke4 h4 (and so forth).

The Neustadtl – Porges, 1901 position is a famous ending, long known to be a win for White. The solution(s) is more than 20 moves long and well explained in the Averbach & Maizelis “Pawn Endings” books (first published in 1950 and respectively 1981) and in “Secrets of Pawn Endings” – Müller & Lamprecht (2000). All these books have been re-printed in the last decade and are available. I don’t know about Freezer but for the position mentioned, probably it would be as useful as Encyclopedia of Chess Endings I - Pawn Endings (2013) – diagram # 1816.

Thank you for the responses and the book references. I just bought the kindle edition of "Secrets of Pawn Endings" and will see what I can learn further about this ending (Neustadtl-Porges 1901)
I need an explanation regarding position #670 on page 204 of "Pawn Endings" by Y Averbakh and I Maizelis. In the left hand column on page 205 after the move 16 K-N4 (descriptive notation) it says "and P-B5+ wins". This means P-B5 wins for white. However, in the notes that follow labelled a, b and c, there is no immediate advance of the bishop pawn. I do not understand what "and P-B5 + wins" means in this context.

This is the position after white played K-N4 (descriptive). The text in the book reads as follows "16 K-N4 and P-B5+ wins". (+ meaning white wins) In the three continuations given in the book, there is no immediate advance of the bishop pawn. After black moves his king, I have noticed that engines contemplate pushing white's bishop pawn but then decide to move the white king instead. My specific problem is that I do not understand the quoted text.
Actually George, when referencing a study, it would be good to give the year and the author rather than just the book and page.
I have three different editions of Maizelis and was forced to go down into the catacombs to find the book you cited. It is dusty there with lots of spider webs, and dangerous, because you could get a nasty shock if you have forgotten what shelves you booby-trapped.
Anyway, beyond the Olms books section, I found Batsfords and therein this:
Hi Wayne, I am new at posting and will provide diagrams in future. Thank you. I too thought that the text indicated as you say that White wins after pushing the bishop pawn but I found that engines don't like pushing the pawn. I would love to see the continuation that Maizelis was contemplating. I have yet to find the win if White does push.
The continuations given in the book are for the three possible black king moves and white does not push the pawn and yet white wins and so I am at a loss to know when Maizelis intended to advance the pawn. If white wins by the continuations given in the text a, b and c then why does he mention "and P-B5 (f5) wins"? It seems that White wins without the advance.

To me it looks a translator/editor error. Russian editions did no mention f5 at all after Kg4.
