Post by MOBMAT »

I was going through some FENs that I was attempting to verify when I found this one.

[d]3B3k/5pp1/5R2/p4pK1/P7/8/p7/8 w - -
It has been around a long time and a reference to it can be found in a thread by Dan Corbit on the Winboard forum

http://www.open-aurec.com/wbforum/viewt ... F8#p185631

It is published with the solution of Rh6+, but not so fast.

Code: Select all

FEN: 3B3k/5pp1/5R2/p4pK1/P7/8/p7/8 w - - 0 1

I don't have a mega-thread PC, so this was found using 4 threads.
SF11 with syzygy doesn't switch over to Rxf7 till 47ply.

Please try the position on some good hardware and let us know what you find.

From this link:

You an see that MES.EPD is from:
MES.EPD "1234 Modern Endgame Studies" by M.A.Sutherland and H.M.Lommer, 1968
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

That test was written in 1968, before the tablebase and strong computer programs.

Here are some other lost positions from test suites:

Hello:

As Dann already wrote, this study is in '1234 Modern Endgame Studies' book. WB Forum locates it in number 699, which is true (page 117 of the book), saying:

It is published with the solution of Rh6+, but not so fast.

@Vince, @Bob & @Dann: in page XXIII of the book (Errata), it can be found the following:
1234 Modern Chess Endings wrote:699-Cooked by 3......, Kf6 wins.
So the study was known to be cooked already in 1968. Avoiding to queen the pawn by moving Kf6 is correct according to engines. This might answer your questions and doubts.

In fact, YACPDB (Yet Another Chess Problem Database) lists the problem in its number 339850:

I could not find the PDF of 'The World Chess' of February 1933 after a brief search. The most I get is the front page from this site:

Don't shoot the messenger! I just noticed the published move was not the best.
I agree Bob, I usually don't care about trying to lose the slowest either.

I have another, this time a better winning move.
[d]3r2k1/p5pp/bpP1p3/3n1p2/2NQpP1q/P3P3/1B1R1R2/4KBr1 b - -
It was published with an ID if "MG 1721", but I found a reference to is as "ECM.216" in the ECM98 list (old!)
The published suggested move is Rxf1+, but the better move is e5.
I wasn't able to find any newer references, so I'm not sure if it has been analysed before.
Found e5 to be M19 with a dev version of SF, but haven't gotten another engine to verify.

There are thousands of wrong test problems. Especially with old problem tests and especially with endgame tests.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: These aren't the solutions you are looking for

After Dann mentioned in another thread the list of FENs which can be found here...

https://github.com/sylvinus/chessathome ... holmes.epd

I ran across one entry that is just basically, well, WRONG.

The entry in question is:

Code: Select all

1K6/8/2p4p/5p2/1P3P1k/4pP1p/4P2P/8 w - - bm Ka8; c0 "level: med-14"; c1 "Study W.Bolanowski, 1.Ka8! wins"; id "EGP 0251";¶
[d]1K6/8/2p4p/5p2/1P3P1k/4pP1p/4P2P/8 w - -
It states, 1. Ka8! wins

Well, not so fast grasshopper. Not only does it NOT win, the truth is that every move by White's King is a draw and the only other move (b5) loses in 13.

Not sure when a draw is a win....perhaps it identifies as a winner! LOL

Here is what SF12 has to say and it was verified with H6/Nalimov

Code: Select all

FEN: 1K6/8/2p4p/5p2/1P3P1k/4pP1p/4P2P/8 w - - 0 1
