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.

What is the winning line for this position. I Can't seem to find the win after forcing bm Rgxf4, but surely an impressive draw.
Is there a winning line I missed or this is really a White To Move and Draw.
I have this:

2Q5/3p2K1/3qp3/2p5/pp3pR1/5R2/b3P1Pp/6kr w - - acd 311; acs 0; bm Rgxf4; c3 "Rgxf4"; ce 32458; pm Rgxf4; pv Rgxf4 Bd5 Rf2 Qxf4 Rxf4 Kxg2 Qxc5 Rf1 Rg4+ Kh1 Kh6 Rg1 Rxb4 a3 Qf2 a2 Rh4 Rg2 Qf6 e5 Qxe5 Be6 Rf4 Rg3 Qe4+ Kg1 Qd4+ Kg2 Qf2+ Kh1 Qf1+ Rg1 Qf3+ Rg2 Qa8 Kg1 Qa7+ Kh1 Qd4 Rg3 Rf1+ Kg2 Qf2+ Kh3 Rh1 Kg4 Qxh2 Bd5 Qh4+ Kf5;
Pretty win. Thanks for the position, and solution.

Good question. I am analyzing a couple hundred EPD positions right now that are candidates.
They are all early checkmates, in that at least one side has not castled and there are 25 chessmen or more on the board.
They are also mates between 11 and 22 (IIRC) but that could get changes with the analysis and more than half will simply be discarded immediately due to multiple solutions.
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.

Hi Dann,

good work!
Maybe you will find material in my big databases from SWCR, FCP rating list or Wasp test-games.
A lot of such mate postions you will find here.

It is a good idea to take a look.

Hi Dann,

yes, because all the games from myself are without resign mode.
So games ended with mate and the chance to find good material is higher!

I have been working on a test set recently, but today I thought to myself, "There are a lot of smart people on CCC who could help make this into a really great test set."
Here is the current list:

Code: Select all

...
1q1N4/3p4/k1pP1Bpp/1pP5/pP2K2P/P7/8/8 w - - bm Be7; 
I have resolved all of them to checkmate. But here are the problems:
1. Some probably have more than one solution.
2. Some are too easy
3. Some are too hard
4. Some are semi-duplicates
5. Some are too contrived [*]
6. Some are not artistic enough [**]

[*] If they are beautiful enough, we might still want to keep them
[**] probably the biggest problem, because things I like other people might not like.

I have recently seen some really brilliant contributions from forum members and I am entirely convinced that a group effort would make a better test than me with my puny brain all by myself.

So I want to judge the interest in such a project. Does anyone want to get involved?

I am also involved (often) in other efforts that take my computer time, so compute resource also comes into play.
Have all of these been resolved?
This one was tough.

Code: Select all

FEN: 1q1N4/3p4/k1pP1Bpp/1pP5/pP2K2P/P7/8/8 w - - 0 1
