Game uses the Courier 12x8 board and adds knight compound pirces. (12x8, Cells: 96) [All Comments] [Add Comment or Rating]Graeme Neatham wrote on 2017-03-10 UTCHi Malcolm, Thanks for your interest in this variant. The move to the 3rd / 6th ranks for the Pawns was the last modification made to the starting array, and was an idea taken from Makruk (Thai Chess). It was done to balance the loss of the Pawn's initial 2-step movement and the loss of castling. I did not see the undefended a, e, and l pawns as detrimental to the game. The number of pieces for each compound type was based upon my estimates of their relative strengths - one of each for the more powerful and two of the least powerful Courier. In naming the piece types I try to ensure that the initial letters of the names different from each other.

Graeme Neatham wrote on 2012-05-04 UTCI have started to recast the wiki page in wiki-syntax - hopefully this will speed up the page-loading. The descriptions are intentionally brief as for the most part I would otherwise be repeating the descriptions from Eurasian Chess. The pawn image clearly shows a white pawn that has crossed the river. Graeme Neatham wrote on 2012-05-03 UTCI will allow that the description on the chessvariants wiki might be a little terse, but I think it at least adequate, with each non-compound piece having a movement diagram.

The command/control structure may be used to determine movement of non-command units/pieces. Have a look at Joe Joyce's Chieftain Chess for an example of an hierarchical game. Whether or not the term "wargame" is sufficient by itself is debatable. In the context of CVs it probably is. Graeme Neatham wrote on 2012-04-14 UTCIn game theory Hierarchical Games model conflict systems with a structure of control levels ranked in a certain order. Thus in a wargame there might be an overall commander, several sub-commanders, and many unit commanders, per side. Troop movements and performance would depend upon the placement and movement of these commanders.

With a composite primary key, will it search individual keys until it finds a match instead of directly knowing where to go? It is quicker to traverse a numeric key than an alpha or alpha-numeric. But it is not just a question of machine performance - development time including code production (manual and automated) and testing can be less efficient with composite primary keys. There is also the question of maintenance and the persistence of natural composite keys when compared to surrogate primary keys. But this isn't the place to conduct a seminar in database design and I have already declared myself guilty of misapplying enterprise practice - it isn't easy, sometimes, to put aside work practices gleaned over 3 decades. Graeme Neatham wrote on 2012-03-10 UTCRelational Database terminology: Candidate Key - a column or set of columns providing data that is unique for each row. Where a set of columns is involved the term Composite Candidate Key is used. Primary Key - the Candidate Key that is the main index for a table and which will be used as a Foreign Key in other tables. For performance purposes a Primary Key will usually not be Composite. Foreign Key - the Primary Key of another table. Key - when used without qualification will normally be understood to be shorthand for Primary Key Self-rating - personally I would be wary of such a practice, not because I think inventors are always going to give maximum marks to their own games, but because they are too close to their own games to provide a disinterested assessment. Overwriting of data due to revision of values leading to loss of historical data strikes me as being what would be called 'bad practice'. But I guess I'm guilty of trying to apply corporate standards in a non-corporate situation. Graeme Neatham wrote on 2012-03-10 UTCJust a few thoughts about the Likes table: It might be useful to include an ID for the item's creator. I know this can be found by joining through the ItemID but keeping it in this table as well would enable faster queries concerning games inventors. It would also make it easier to stop creators rating their own games (UserID != CreatorID) Will a user be able to revise their ratings? If so the table will need a timestamp field and possibly either a binary current/superseded field or a status field. Or previous ratings might have their own table - LikesHistory On Designing Good Chess Variants.

And the comparison with your variants is certainly interesting - particularly so with my newly added 10x10 subvariant.

Hopefully my Zillions file will be posted here soon. Cheers Graeme Graeme Neatham wrote on 2011-03-03 UTCHi Nick, I'd thought about the 3-step first move for a pawn, but decided to leave it at 2-steps as I was trying not to move too far from FIDE.

[Subject Thread] [Add Response]Graeme Neatham wrote on 2011-02-02 UTC Yes I played chess before discovering chess variants. I played for my school team and at university, and when I got my first job for a London based insurance firm I played for them in the London Insurance Chess League. I also played in some local leagues and chess tournaments. These activities came to a halt with the arrival of children and a career change from insurance to IT. Although I still play chess, my real passion is for wargaming (also started way back in my school days) and much of my gaming time is taken up with perfecting my own set of rules for my own particular circumstances. Most of my CV designing is inspired by ideas from other activities - like my degree studies with the Open University - and tend to be very conservative in terms of pieces used. BigBangChess. Pieces start off-board; the board expands and contracts during play.

Can you get the queen before placing the remaining four pawns? Are captured pieces droppable?' Sorry, but I'm unclear what point you're making about the contraction capture image. Can you elaborate please? There are 4 drop levels, and each side begins the game on the first level. At this level only Pawns can be dropped. On dropping the fourth Pawn the level for that player advances to the second. On the second level Knights and Bishops can now be dropped as well as Pawns. The third level is reached when the second Knight or Bishop is dropped. Rooks may be dropped at the third level. Dropping a single Rook advances that players drop level to the fourth level. Once the fourth level is reached the Queen may be dropped. Captured pieces are removed from the game. They cannot re-enter the game by being dropped again. Pentagonal chess. Missing description (8x8, Cells: 64) [All Comments] [Add Comment or Rating]Graeme Neatham wrote on 2010-08-31 UTCAnother board of pentagons that might be of interest is this: And why the colours? I just think it looks nicer when presenting a board with no game context. Of course if the board were to be used in a variant, the number of colours and their placing might need more careful consideration. Graeme Neatham wrote on 2010-08-29 UTCGood ★★★★The concept of using forward/backward irregular pentagons to construct a playing board is excellent. Rather than using a single off-set direction I would be inclined to switch the off-set direction to produce a playing board like this - It might also be interesting to have left/right pentagons, like this - Quantimex.

I was thinking of adding a note on using random assignment of the final destination hex as a variant, but in the end decided that the Quantum concept was already radical enough in itself. Play testing has been minimal. I used Zillions running a non-quantum version to test and refine the transfer of Ultima to a hex board, but have not yet been able to get a working Quantum version. I have just finished constructing a non-enforcing pre-set and would be happy to push a few pieces around at a leisurely pace. Spherical Guard Chess.

Your understanding about the connection of the poles with their adjacent cells is correct. It should be noted that from the starting position the Horses, although appearing under threat, cannot in fact be captured by the Cannons as this would place the General (King) in check.
