Okay! So here's my suggestions for positions to be eliminated from the test and my reasoning:



Best move is capturing a piece en prise while putting the king in check? Boring (because it's expected.)



The best move is taking the queen with a move that puts the king in check? :shock: Not surprising at all!



Best move is capturing an unprotected knight to put the king in check, zzzzzz...



Best move is capturing the rook with check to win the exchange, nothing spectacular.



Another "best move is capturing a queen with check"...

The other captures with check seem fine, so this only managed to trim 5 positions.

I strongly agree with all of those (it is surprizing that any of those positions could have given an engine pause, since they are all obvious moves).
I guess that 90% of the people here would play those moves after a couple seconds.
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.

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: A community project CCMT

Post by Ovyron » Wed Jul 08, 2020 5:14 am

I suggest we separate them into two lists, one is the ones we've decided to definitively keep for the CCMT project, whenever this list reaches 100, we're done (since you don't want more than 100), so the rest would be auto-eliminated (you keep the first 100 most liked.)

I think that minor underpromotions are always fun, every time I see a test that includes a promotion, I think what would happen if it was to a Knight or Bishop (or Rook), by this criteria I think all the ones with such promotions would be saved.

Then the lists would look like this:

Current positions in the CCMT project (6 out of 100. 94 remaining to be added):

I've eliminated these 4 based on the criteria that we should only have unique solutions:






Did I make a mistake or are we really 42 eliminations off from being done? This looks so close all of a sudden! :shock:

I killed almost half of them with a simple SQL query that looked for any alternate move with a score of more than +10 pawns, since obviously those moves also win (most likely anyway, there could be some draws with huge material imbalance).

Since you found some others with alternate moves, that shows why it is good to get alternate people involved. I had done multi-pv analysys but as they say, "another pair of eyes can't hurt".
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.

BTW, Ovyron,
I want you to know that I really appreciate your efforts on this.
You have clear talent for building a test set.

I appreciate that, Dann :) - a key part was when you mentioned you wanted positions that were fun, then eliminating or saving positions became fun in itself (curating chess positions).

I just had another idea for elimination criteria: boring checks. I guess they're interesting by themselves because they're checks that seem very obvious to humans, but difficult to find for computers. But, fun? For fun we need that these positions hold up by themselves without having to check an engine. I think.

So I've gotten rid of boring checks and have included my reasoning at the bottom.

I've also added the 20 most impressive checks to the saved list, these checks are completely unexpected and one can't see the right continuation easily. What makes them special is that their difficulty depends on whether you're told "look for a check" or not (but being told that doesn't make them easier!)

The only check that leaves the king with only one option to move.



Nothing wrong with one where a single queen turns this around, but this is basically the same one with Qg4+ as solution 4 positions before.



And, huh... this one :shock:



Okay, we don't really need more of these queen against entire army positions...



"Capture the queen for grabs with check."



Check to fork King and Rook.



Very cool! But it's just another position we already have one move later.



With so many pieces able to capture a pawn with check, a queen check is boring.

While doing this I realized it could be simple to "fix" some of these positions by making subtle changes, for instance:



With a black queen on e5 this is a dead giveaway. But when it's a pawn it suddenly becomes great! But it's not that we don't have enough positions and need to create new fixed ones, eliminating is the way to go :mrgreen:

MIght be nice to leave a single queen against the army position.
Keep those createive thoughts at high revolutions.
At some point we may need to turn a queen into a pawn to maximize the fun.
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.

Alright! I sorted the candidates alphabetically to find them, and moved 2 to the saved list (the other one is queen against army of pawns which is a fun variation.)

This eliminates 11 variations of the same idea, posted at the bottom.

But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
