Dear Mr.Afek,

I use Chessbase as my database for games. It facilitates downloading of games (beginnning from the initial position of pieces on the board) but not snippets of games or downloading positions of end-game studies (and the notations of the solution and of the analysis). Could you direct me to or suggest me some software which is meant for downloading and holding endgame (and middlegame positions and limited moves mate problems and their solution with analysis.
I wonder whether there is any software which allows backward movements of pawns including their 'un-promotion' moving of the King into check, 'un-castling' 'e.p. un-capture' etc.? I am sure you will readily appreciate what I am driving. If there is any such software which allow one to move pieces backward from an end-position of a study, I am interested and if the software also provides an engine which analyses the position arising at any point during the regression it will be well on its way to compose studies. How do you look at the possibilities? I will be glad to hear from you.
Thank you,

STS

Dear Mr. Afek

I would like to have a go at the 9 stuedies set as task at the Corus Chess and Studies day (31/ 01 /09). Could you have them e-mailed to me ?

2. Years back I had suggested to A J Roycroft that there should be studies composing competition where the competitors 'add flesh' to a known end-position (EP) with of course a known result. I have in my collection about a dozen studies which have, in effect, the EP of the famous Saavadra win study. He said that I was ahead of my time and, to my knowledge, the matter rests there. I was then subscribing and occasionally contributing studies to AJR's EG and then had some correspondence with him. (i used to enjoy solving your studies in EG issues.) I believe the idea has not been put to use in any of the study composing tournies and if you feel upto it, please spare some time and e-mail your views to me on this.
3. In fact, I had written an Article titled 'Re-use of known end-positions' and sent to AJR and am not aware whether it saw the light of the day in EG. I can, of course, e-mail it to you for whatever you would like to do about it (maybe, in consultation with AJR), besides giving it a reading. Please let me know.

4. I stumbled on this column while surfing. But I was under the impression that the foray of computers marked the end of Study Composing Tournies. (I don't compose now and I as unaware about developments.
Incidentally, could you refer me to any website where I can update my knowldge about whether computers can composed or have composed end-game studies and especially articles dealing with this. If computers can't 'compose' then why not? You will surely have your own take on this.
Hoping to hear from you soon,

Mr. Afek: Latest Bazlov study you extend the variation 4. Nxf4? to 6....Kf6! But then 7. Kf3 surely wins. What am I missing?

@Cutrite:

If I may respond for Mr Afek:

You are missing nothing. If 6. Rh4, then e.g. 6. ..., Bd6 =.
But in the case of 6. Rf1, then 6. ..., Kf5! is indeed compulsory. See my post to Weekly Endgame Study (107).
