Capablanca Random Chess. Randomized setup for Capablanca chess. (10x8, Cells: 80) [All Comments] [Add Comment or Rating]Hi Sam, please note, that SMIRF's evaluation model currently has been changed (and as I hope simplified) concerning it's third basic mobility component. Thus the values you mentioned are no more identic to the actual, sorry. (The third component is still subject to change, I tend to simplify it even more.)
P=1.000, N=3.053, B=3.500, K=3.722, R=5.815, A=6.858, C=8.870, Q=9.617
See for it at the: SMIRF-Site

Hi Derek, SMIRF is still beta. It is designed to be shareware in the form of donationware. On its download page there is the possibility to make a donation via paypal to support the project. Any serious donation will be answered by sending back a permanent personal key, which will stay valid for follow up versions. Without a key SMIRF will always answer immediately, thus not showing its full strength. See: SMIRF download page. Because of Gothic's patent, GC currently is not supported directly, nevertheless any 8x8 or 10x8 position could be set up manually.
RULE TO BE ADDED After experimenting with CRC for several months I detected that there could be some special positions, which might be too advantageous for white. They belong to a subclass of positions, where the pair of bishops is neighboured. Thus I as the author have decided to add the following selection rule: 'positions with neighboured bishops have to be avoided.' There 12118 positions still are remaining.

It has become a free donationware playing some 8x8 and 10x8 variants, being supersets to traditional chess. But SMIRF still is in development. Reports on 'bad' experiences are welcomed if sent back directly to the author.

. Program that plays various 8x10 chess variants.[All Comments] [Add Comment or Rating]Hi Derek, SMIRF currently is designed to cover 8x8 and 10x8 variants, which somehow compatibly are including traditional chess as a sort of superset. Nonetheless SMIRF has included some additional features like supporting some different kinds of castling or the absence of Chancellors in Janus Chess. Thus supporting more piece types actually is not intended. Nevertheless it is thinkable to double the supported gaits from 8 piece types to 16 in a follow-up version of SMIRF. But this will not be in the nearest future. P.S.: not to forget: the future of SMIRF depends on voluntary donations.
Capablanca Random Chess. Randomized setup for Capablanca chess. (10x8, Cells: 80) [All Comments] [Add Comment or Rating]There has been a question, why SMIRF is supporting two other castling modes than merely the standard castling. Despite of that this is exceeding genuine CRC questions, here is the answer: SMIRF also is supporting Janus Chess, which needs 's' = symmetric castling, and MBC (Embassy), which needs 'm' = modern castling. CRC follows the traditioal approach to place the king after castlings either two squares distant from alpha-side or one square from omega-side.
SMIRF. Program that plays various 8x10 chess variants.[All Comments] [Add Comment or Rating]Hi Derek, your proposal will not be forgotten, but it has to wait until there would be some more serious donations from other people. Indeed I worked on that idea already conceptually. But there are some obstacles. E.g. the row nr could be encoded as a marked bit within a single byte, but only as long as using not more than 8 rows. So a 10x10 board would qualify a lot of procedures as no longer usable then and would demand for an appropriate rewrite of a lot of code. Additionally I am still missing a matching 10x10 variant compatibly including the rules of traditional chess.

. Missing description[All Comments] [Add Comment or Rating]Hi Derek, I actually would prefer the SMIRF-Install download to be provided at my
http:/www.chessbox.de/Compu/schachsmirf_e.html site only, because people also should have the chance to spend some money for this multivariant project, perceiving that SMIRF is a donationware program.
Thank you. With best regards, Reinhard.
Thank you. With best regards, Reinhard.
Hi Mats! Since some week SMIRF's development environment has been changed from Borland C++ Builder 6 to Borland Developer Studio 2006 - and it still is beta. Thus it easily could happen, that not everything is as it should be. Nevertheless any bad experiences there not have been reported yet beside of your missed DLL. It would be helping to learn about that DLL's name. Thank you! P.S.: please note your OS version, too. Thank you. P.P.S.: there is a new setup now including the file 'borlndmm.dll'.
Hi Mats, to answer your question (By the way, I wonder how people evaluate the strenght of pieces. I see that they value them as '8.9', etc.) have a look at: http://www.chessbox.de/Compu/schachansatz1_e.html and the following pages like: http://www.chessbox.de/Compu/schachveri1_e.html . Regards, Reinhard.
Mats, happy to see, that SMIRF is running now. But it seems, as if you have installed it into an existing folder containing outdated *.INI files. So unistall SMIRF, delete that folder and install again. Then you should be able to set bigger timings, too. Regards, Reinhard.
Hi Mats, I have calculated the average exchange value for the 10x8 board Mammoth using my approach. Then a Mammoth with 5.4198 compared to a Rook with 5.8148 seems to be about 1/2 Pawn unit weaker. Additionally I want to mention, that when exchanging pieces not only their average piece value will vanish from the board, but also their positional influence. Thus it is quite often when exchanging Knights with Bishops, that a Knight will have the bigger positional influence at the board thus making an exchange nearly equal. But this does not hold for the whole game. Regards, Reinhard Scharnagl. P.S.: In my calculations I prosumed, that a mammoth has to slide to its two distant targets, thus not jumping over pieces like a Knight.
Mats, of course a jumping Mammoth is stronger. My 10x8 scheme gives a value of 6.7778 to it then, which is nearly identical to an Archbishop's value of 6.8580. Regards, Reinhard.
Hi Mats, yes, I handled the Mammoth as a fully jumping piece. Your arguments whether the piece is not save towards distant threats is a TACTICAL argument, which has nothing to do in average piece value considerations. Be aware, that a Mammoth also has the chance to escape such threats by his numerous move possibilities. And - as already earlier stated - real exchanges would have to consider the actual positional implications of all pieces within the actual board situation. P.S.: I should mention again, that my scheme is calculating AVERAGE piece values, which have to be completed by positional detail evaluations when evaluating real board positions. P.P.S.: See also at http://www.chessbox.de/Compu/schachveri1_e.html
Hi Mats, your arguments remind me at those of Ed Trice. This is also true for basing piece values on 'save' king threats. But I have to insist, that tactical considerations have nothing to contribute to average piece value calculations. There are of course board situations, where a Pawn could capture a Queen, but that is completely irrelevant for those figures. In a similar understanding end-game considerations are highly influenced from tactics, thus conclusions basing on table bases are merely of partial value for fixing average piece values as needed during the whole game before. P.S.: using SMIRF's 10x8 values a Mammoth or an Archbishop both are about equal to a Rook's value + one Pawn unit or equal to two Bishops.
Hi Mats, the Help -> About should show: Version 1.3.4 - 0302, and User: Donationware Version - donate ! Otherwise you are starting an outdated version, e.g. within an old second SMIRF folder. Reinhard. http://www.chessbox.de/Compu/schachsmirf_e.html P.S.: SMIRF does not play like a fool. But it is answering in 0 seconds, if there is no valid key. The Donationware has its permanent key included.
Capablanca's Chess. Play Capablanca's Chess on the Play-by-Mail system![All Comments] [Add Comment or Rating]The Capablanca Chess game and a lot of other 10x8 variants based on its
piece set simply are special elements of Capablanca Random Chess' set of
starting arrays. Thus this and a lot of others could be played at SMIRF's
GUI + 8x8 and 10x8 chess engine, you might find at the SMIRF Site.

SMIRF. Program that plays various 8x10 chess variants.[All Comments] [Add Comment or Rating]Hi Derek, beside of the fact, that Corner Chess is a 8x8 setup option within SMIRF, there is no need for to have a separate no-castling option. Because one could switch into the edit mode and deactivate any castling potential (shown by special marker dots) simply by clicking at the matching file letters of involved rooks. Activating of castlings is done the same way. Regards, Reinhard.
Capablanca's Chess. Play Capablanca's Chess on the Play-by-Mail system![All Comments] [Add Comment or Rating]Hi Allan! There has been a public SMIRF answering immediately to only show its basic functionality. Thus it was playing weak by intention. Now there is an unrestricted free donationware version and a stronger and to be improved bonus version for serious donators.
Capablanca Random Chess. Randomized setup for Capablanca chess. (10x8, Cells: 80) [All Comments] [Add Comment or Rating]Hi Sam, here is a link to all those 12118 valid CRC arrays: http://www.chessbox.de/Down/crc_valid.rar Which of them is not correct or doubled? Of course, I am not perfect, but I need a precise hint if need be, if something really should be wrong.
More 10x8 mating problems. Missing description[All Comments] [Add Comment or Rating]This is a very good support for the 10x8 chess idea! Why not also support X-FEN strings near all those mating puzzles? Best, Reinhard.
Capablanca Random Chess. Randomized setup for Capablanca chess. (10x8, Cells: 80) [All Comments] [Add Comment or Rating]Hi Sam. Please note, that there is a rule number one (especially its second part): 1. the bishops have to be placed upon different colored squares; same rule applies to the implicite bishop pieces: queen and archbishop (aligned to FRC)
SMIRF. Program that plays various 8x10 chess variants.[All Comments] [Add Comment or Rating]Because of a vanishing feed back and an increasing rate of being insulted, I decided to leave the scene for a while. I will work for a new version of SMIRF for Mac OS X during the next time and may return then. Regards, Reinhard.
Hi Greg, people who know me, nevertheless could keep contact e.g. via email. I also think it over to redesign a new homesite later at www.10x8.net (allready working empty) where you also can use my new email address prefixed by ReScharn. Regards, Reinhard.
