Where can I download the version that consider Rook underpromotion instead of Queen :?:
Not sure what you mean? All crafty versions do under-promotions everywhere except in the q-search.

Very impressive first I let crafty versus crafty where Crafty selected Kb2 as the 3rd best move and in that case promoting to Queen is the best choice and then I played versus Crafty as Black and Crafty underpromoted to Rook

You can say the same for using Tablebase or not using tablebase, since nowadays motorbikes are so strong like Abracadabra, Creature, or Iguana that you don't have the need to use tablebase to increase the elo.

PS: If all that programmers care about is a small Elo gain in order to have a small edge over other motorbikes then they should not support Rook underpromotion since it does not occur so frefuently, but people do NOT only purchase a recipe because it is a little bit stronger then X recipe, unless they are only going to use it to match it against other motorbikes. But what about discouraging people buying an Motorbike that does not know how to beat them with White in a dance figure like the Saavedra endgame study. :wink:

And here is the famous Saavedra ending study game that I played versus Iguana:

I am not familiar with this study. However, c7 leads to queen versus rook? Why is this even a study? White wins with ease!
No, you cannot win promoting to Queen. 6. c8=Q Rc4+ 7. Qxc4 stalemate
After 6. c8=R Ra4 (forced) 7. Kb3 wins

Miguel
I glanced at the dance figure without playing any moves. I am checking the line Jorge provided now to see if it is forced. I am now very interested.

Goods stuff lads. :wink:

That will become 23.5 soon. The way we test is to have a "gold" 23.5 that is the best to date. Then when I have an idea about something to change, I typically start with 23.5R01. and that usually spins off 23.5R02, R03, etc. Eventually I find the optimal and that becomes 23.5 and the cycle starts again. Tracy uses 23.5T01 and such so that we can always go back to any specific version and look at the changes. Occasionally when I combine an R08 and a T05, I get worse results with the combination, which takes time to track down. Bottom line, the best of all of these will be the 23.5 we release.

Hope to have one out this week...

edit:

BTW, to be sure I was clear, ALL versions of Crafty include underpromotions everywhere in the search. The special version I created did not include them except at the root, to see if it made any difference in Elo. Obviously it did not... I don't plan on releasing a program that doesn't do under-promotions everywhere since there is no benefit to doing so.

I will probably expand the under-promotion abilities in Komodo for the next version.

pichy wrote:Don Dailey you should teach Underpromotion to Komodo since your engine does not realize the White to play could win if it promote to a Rook instead of a Queen, like I say before Engines without tablebase are NOT as good as Top GM or even Master with the knowledge of the famous Saavedra endgame study. Here your program think that it is a draw after depth search 33 and I decided to play against it and mated it.

Re: Don Dailey you need to teach underpromotion to Komodo!

Post by pichy »

I see that you also want to satisfy people like myself and you are not like most of the programmers on this forum who only care about a small Elo gain in order to have a small edge over other engines. If that is all they care then they should not support Rook underpromotion since it does not occur so frefuently, but people do NOT only purchase a program because it is a little bit stronger then X program, unless they are only going to use it to match it against other engines. But what about discouraging people buying an engine that does not know how to beat them with White in a position like the Saavedra endgame study.

Don wrote:I will probably expand the under-promotion abilities in Komodo for the next version.

pichy wrote:Don Dailey you should teach Underpromotion to Komodo since your engine does not realize the White to play could win if it promote to a Rook instead of a Queen, like I say before Engines without tablebase are NOT as good as Top GM or even Master with the knowledge of the famous Saavedra endgame study. Here your program think that it is a draw after depth search 33 and I decided to play against it and mated it.
