Not so surprising actually.
I believe this endgame was discussed in CCC not long ago, it requires
a different kind of knowledge than the usual drive to the side and mate heuristic.
Crafty, like many other engines, probably lack this exception to the general rule.

Hello Slobodan,
I will bite on this morsel.
Precisely what does your post mean in the grand scheme of things?
That Crafty's endgame technique is lousy?
Can we measure the performance of other engines to see their technique?
Why oh why would an author go through the trouble of giving their engine the ability to use egtbs just to have someone post that the engine cannot handle a position that would be trivial with the four piece egtbs installed?
Just seems strange to me but I am willing to learn....
My two cents.

Not so surprising actually.
I believe this endgame was discussed in CCC not long ago, it requires
a different kind of knowledge than the usual drive to the side and mate heuristic.
Crafty, like many other engines, probably lack this exception to the general rule.
-S.

No
It is very surprising because Crafty knows to win KQ vs KR without tablebases and I thought KQ vs KN needs exactly the same knowledge.

I can add that when I look at the game crafty even did not try to centralize the king and certainly did not try to reduce the distance between the kings.

I think KQKR works just fine with the squeezing to the corner idea,
in KQKN you probably have to seperate the knight from his king just as in KRKN.
Ok, I don't know what Crafty tries to do. I think maybe only squeeze to the
side, but the side does not work as well as the corner in my experience.

Of course, when the game gets down to 4 pieces, the EGTB's would take care of it.
But ...
Probing the EGTB's in search is costly. Disk access is slow. That is why most (if not all) programs do not probe in the quiescense search. And guess what: The quiescense search is all about evaluating what happens after a capture sequence. Also what happens after a capture sequence that leads to an EGTB position. Probing the EGTB's are too expensive, so the evaluation should know if a position is favourable or not.
So endgame knowledge of basic endings is still important. It may find key moves in an ending a few plies earlier.

After reading a bit more carefully, the above does not apply to the KQ-KN ending that was the subject of this thread.

There is no problem in KQ vs KN to know if the position is favourable or not favourable for the queen so this is not relevant for this case.

You dismiss my idea with a hard and confident "no", but still it seems you don't really know for sure either?
I haven't tried centralizing the king though. I would definitely think that
hunting the knight to a corner would be a more direct strategy, that's assuming you can seperate the two in the first place. In KRKN that's not always possible but a queen should offer much better chances of course.

Then it will remain a mystery what Crafty tried to do until one of us looks at
the code

Richard, I agree in general. But KQKN is really easy in this context. Just eval it as win for the Q, and wait until the pos is on the board, when TBs take over. It would not matter, if the eval accounts for a really good KQKN position or a difficult one, when you decide to trust the TBs later (many other positions are similar). Of course you argument is important, when the position/material constellation is not that clear.
For aesthetical reasons, I would prefer my engine to be able to win KQKN without TBs. I did not try yet, but will soon ... If it doesn't, I will probably fix it, even when it is no issue for playing strength under my typical setup.
This reminds me of KRKN and KRKB. I remember Gearge posted here once some interesting ideas about it. Does anybody find those posts? For these positions, better knowledge could also help, even when using TBs.

Dieter

Not so surprising actually.
I believe this endgame was discussed in CCC not long ago, it requires
a different kind of knowledge than the usual drive to the side and mate heuristic.
Crafty, like many other engines, probably lack this exception to the general rule.
-S.

No
It is very surprising because Crafty knows to win KQ vs KR without tablebases and I thought KQ vs KN needs exactly the same knowledge.
Uri

I think KQKR works just fine with the squeezing to the corner idea,
in KQKN you probably have to seperate the knight from his king just as in KRKN.

No
I think that in KQ vs KN search and the same knowledge of centralizing the king
and reducing the distance between the kings should be enough.

You dismiss my idea with a hard and confident "no", but still it seems you don't really know for sure either?
I haven't tried centralizing the king though. I would definitely think that
hunting the knight to a corner would be a more direct strategy, that's assuming you can seperate the two in the first place. In KRKN that's not always possible but a queen should offer much better chances of course.

of course but I think that KQ vs KN is easier than KQ vs KR and the same strategy that helps to win KQ vs KR should help also in KQ vs KN.
I simply use common sense and I never saw a case of a program that failed to win KQ vs KN before this game when i saw cases of failure to win in KQ vs KR.

Where will it all end?

Engine X cannot handle the Gutchpa line in the reverse King's Indian - please let there be no such opening! - without its opening book!

But you don't try and centralize the king when winning KQ-KR, you drive it to
the corner. Only in the corner can you create the kind of mate threats that is
needed to finally win the rook.
It does seem simpler than Q-R, but I haven't tried it.
I just don't see what centralizing the king would accomplish.

I try both in movei.
I try both to cenrtralize the king,push the opponent king to the corner and reduce the distance between the kings.
My point is that I believe that the same strategy that works in KQ vs KR that does not look at the distance between the king and the rook should work in KQ vs KN.

Hello Slobodan,
I will bite on this morsel.
Precisely what does your post mean in the grand scheme of things?
That Crafty's endgame technique is lousy?
Can we measure the performance of other engines to see their technique?
Why oh why would an author go through the trouble of giving their engine the ability to use egtbs just to have someone post that the engine cannot handle a position that would be trivial with the four piece egtbs installed?
Just seems strange to me but I am willing to learn....
My two cents.
Later.

Looking up moves in a list is easy, but that's not playing chess...
My two cents...

Dave

Looking up moves in a list is easy, but that's not playing chess...

The elegant solution is almost always the best solution.
If a list lookup is easier and more reliable, then it is also better.
If the techniques to solve the puzzle still work when there are enough men on the board to render the tablebase files moot, then the general techniques are a good idea.
If the techniques are 1 by 1 special cases that will bloat your eval and not make the program stronger in general, then they are a bad idea.
My idea of a good endgame eval would be something that knows general principles. If no obvious principle directs the move, then a bitbase perfect knowledge lookup is what is wanted. For the pv, then use real tablebase.
I suspect that most endgame ideas translate well to many phases of the game and are therefore valuable to add to a general purpose evaluator.
Another interesting idea is to do like Dark Thought and have installable evaluation functions. Then, you can change the evaluator as the game progresses if you like.

Looking up moves in a list is easy, but that's not playing chess...
My two cents...
Regards
Dave

Hello Dave,
Point taken but consider two things:
(a) Prove that engine X (as long as we are not talking about Shredder)which solves the position without egtbs is better than Crafty.
(b) Isn't the playing of moves out of a book - human or silicon - a version of list lookup carried on at the opening? The fact that it is done rapidly simply means that sveral GM and master level games evaluated such and such a position as being even or better for either colour.
I just think that the more features you put in an engine due to your own abilities is the more you should be rewarded. Why penalise an engine by playing without a book or egtbs and then make a case in bold print when you make a discovery that hey, the engine draws a game when it should win it without egtbs? Is the payoff that significant?
What tells a GM that such and such a position is a good one? The best research points to GMs having a memory tank of hundreds of positions - middlegame and endgame.
Sounds like a table lookup to me.
Later.
