Atlantean Barroom Shatranj. Atlantean Barroom Shatranj Rules. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]

On 8x8 [or even 10x10], the Twisted kNight is about the value of a queen, and probably a bit more, I suspect. The TN has pretty much the same relation to the queen that the bent shaman has to the rook, as far as I can see. In the middle of an 8x8, the TN attacks 24 squares, most in 2 ways. It's a tough piece. Actually, the reason I designed Lemurian was to reduce the power of the Barroom pieces.

Joe, how would you analyze the strength of a Twisted Knight? Specifically, on an 8 x 8 board?

Actually, Abdul-Rahman's upgraded version of Charles' patient pawns is something the Atlanteans would like. Keep digging, you may have made yet another Atlantean archaeological discovery. 

The following is copied directly from Abdul-Rahman Sibahi's Queen of the Night:

'Pawns : these are replaced by an improved version of Charles Gilman's
Patient pawns. When in their second rank, a pawn may move one step forward,
two steps forward, capture a piece diagonally forward, or move one step
forward then captures a piece diagonally adjacent. It also may may make a
non capturing move one step to the side. 

In short: these pawns effectively compound Lias's Pawns with Patient

In the Longer Board (10 ranks) the pawns on the third rank also have the
option to move, without capturing, one square orthogonally backwards. From
the second rank, they have the option for a triple move, and a double move
followed by a capture. A pawn can go back and forth between the second and third
ranks as the player pleases, but once it's on the fourth or beyond it can't
retreat. (Four pawns are placed on the second rank in front of Knights and
Bishops, to maintain the 50% density.)

Pawns may be captured en-passant in case of double or triple step, but if
the final step was a capture this doesn't return the captured piece.'

Jeremy Good wrote on Sun, May 31, 2009 12:17 AM UTC:
Or if not 'normal' pawns, how about Patient Pawns, which Gilman invented and Rahman-Sibahi used in Queen of the Night Chess.

Jeremy Good wrote on Sat, May 30, 2009 12:03 PM UTC:
I hate to be saying this so quickly on top of my Shatranjian Shooters suggestions, but the one step pawns seem a bit onerous for this particular game, out of keeping with the vivacious dynamics of strong pieces on a 10x10 board. I think I've mentioned this to you privately, Joe, but I want to recommend a version of this game with 'normal' pawns, i.e, having the initial double step option with en passant.

Suppose going from c4 to c5 and both legs mandatory. Pathways are c4-c6-c5, c4-d5-c5, c4-d4-c5, c4-c3-c5, c4-b4-c5, c4-d5-c5, six-way. If both legs mandatory, then all six ways have significance. For all the different squares reachable, both mandatory and darter maximize the significance of multiple pathways, I think.

George Duke wrote on Tue, Nov 25, 2008 12:05 AM UTC:
If second leg is optional, ZZG to Dabbabah square is only one path, not six as I was thinking and Joyce describes. As they do ask all the time for Falcon, have you thought of eliminating the leap component and making a change to two square orthogonal darter plus King? (That would still be Joe Joyce's piece to my simple standards, a serial ''orthogonal'' two-step plus/''both-or-twice'' one-component in either order and any direction.) Then six paths have significance sometimes to (0,2). Either way it is nice new piece after Jetan, that influenced me for 15-year-old Falcon and 12-year-old Scorpion and Dragon.

💡📝Joe Joyce wrote on Sat, Nov 22, 2008 05:59 AM UTC:
George, Fergus, your comments are interrelated, so I'll answer them together. 

First, there are [at least] 4 squares that are 3-path. The squares 4 away orthogonally are reached in 2 jumps orthogonally, for 1 path, and in jumping diagonally 'forward' but right or left of the path, the twisted knight moves, you have 2 more paths. If you choose a square 2 away orthogonally, there are the same 3 paths as above in miniature - that is, there are 3 '1-square + 1 square' moves -1 set of wazir moves, and 2 sets of ferz moves. There are also 3 2-square paths. The first is the straight 2-square dabbabah jump. The other 2 paths are alfil then dabbabah jumps. This is 6, but it could be considered only 5, because the 2 wazir steps are over the same squares as the dabbabah jump. As a total technicality, the dabbabah jump doesn't touch the intervening square [it can be occupied], and the 2 wazir moves do, so they are different paths. 

The 'jumping king' can reach 16 squares at a range of 1 or 2, but it can't reach the knight's destination squares in 1 turn. It would need 2 turns to 'make a knight's move'. But the ZigZag General moves twice in a turn, so it can get to knight squares, as long as there is an intermediate empty square to land on during the move. It moves as the jumping king, then may do so again, changing directions. The king, jumping or otherwise, has no chance I can see. The minimum board size for this piece should be 10x10; it should do well on larger boards. 

I suspect the Twisted and fleXible kNights and the ZigZag General are new pieces. But all of them are amazingly powerful. In attempting to tame that power a little bit, I cut the pieces in half, 'literally', and designed Lemurian Shatranj. The Shaman and Hero are half of the Twisted and fleXible kNight. I believe those 2 pieces might also be new.

This game does break one of Fergus Duniho's design rules. The queen analog can checkmate the king analog by itself

I assume you mean this design principle: Avoid any piece that can force checkmate by itself, such as the Amazon or the Cavalry Chess Knight. I haven't analyzed your game and don't know whether it violates this principle, but I will point out that the key word in the principle is force not checkmate. For example, this principle does not rule out using the Paladin (or Cardinal or Archbishop), which is able to checkmate a King without any assistance from other pieces but is still unable to force checkmate without assistance.

George Duke wrote on Sat, Nov 22, 2008 12:48 AM UTC:
Zigzag General, with optional second leg, becomes related to some of the interpretations of Jetan pieces, but different from all of them. It is one- or two- or four- or five-path varying according to the arrival square. I am not sure if there is a three-way set of squares or six-way without relooking. Actually it becomes the best new piece I have seen this year, preoccupied with other multi-path questions and chatter. Next I should look whether ABS is really a best embodiment for ZZG. It is good that excluded are Knight components.

💡📝Joe Joyce wrote on Sat, Nov 22, 2008 12:36 AM UTC:
Thank you for the rating, George. I'm never quite sure what to say when you give me a good rating. [I'm very tempted to say: 'Who are you really, and what have you done with George?' :-)] You've rated and discussed a few of my games now, this one most recently. I'd like to make a few comments, but before I do, I have to ask: is the ZigZag General in this game appropriately named? It is certainly and deliberately a multipath piece. ;-)

Modern Shatranj, Great, Grand, Barroom, and Lemurian Shatranj are a tightly-connected series, each one growing out of the previous one. Obviously, they are what inspired the ShortRange Project. [Oh, yeah, Hypermodern is in there too, right after Modern.] I owe a great debt of gratitude to Christine Bagley-Jones, my collaborator on the ShortRange Project, effectively a co-inventor of Great Shatranj, and an independent designer of Hypermodern Shatranj. I also owe thanks to David Paulowich and Roberto Lavieri  [another independent designer of Hypermodern] for inspiration and encouragement and most of all, fascinating conversations. 

This game does break one of Fergus Duniho's design rules. The queen analog can checkmate the king analog by itself, even though the king can not only step to the adjacent 8 squares, but leap directly over those squares to the 8 directly beyond them. The ZigZag General is far and away the most powerful piece I've ever designed. It moves 4 squares at most, but can reach most squares within 4 and all within 3 squares when it moves, attacking 64 squares. It steps 1 or leaps 2 in any direction, then may step 1 or leap 2 in any direction again. Its restrictions are that it must stop upon capture and that it may not make a null move. 

The ZZG is a combination of the moves of the Twisted and fleXible kNights, the bishop and rook analogs. Interestingly, while each of these latter pieces reaches 32 squares, the ZZG reaches 12 squares more than either other piece could reach by starting on the same square because the TN and the XN overlap squares within 2 of start. 

This makes it more than the queen, which is just the combination of the squares the bishop and rook reach. On an 8x8, from one of the 4 center squares, the ZZG can reach 56 squares, missing only every other square along the 2 farthest board edges. Now the queen gets an extra pawn value for combining the powers of rook and bishop in the same piece, even though it takes no more than either piece could from the same square. What does the ZZG get for the combination and picking up ~21% more squares?

Thank you, Jeremy. I did enjoy putting this one together quite a bit, even to being inspired by leftover letters for piece names ('T' being rarely used, for example). It seems one decent endpoint to a series of shortrange games. The major pieces should be strong enough to satisfy the power-hungry gamer. You might want to restrict the 50-move time limit to only when both players are playing face-to-face and drinking, though. ;-) Enjoy

Jeremy Good wrote on Fri, Jan 12, 2007 10:51 AM UTC:Excellent ★★★★★
This is by far my favorite of all the diverse Shatranj games Joe Joyce has invented. Though I'd say they are all good, this one is excellent. If chess had evolved differently, with the scheme of short range movers becoming more powerful, Atlantean Barroom Shatranj would surely represent the apex.

💡📝Joe Joyce wrote on Wed, Jul 12, 2006 07:46 PM UTC:
Heck, no! More variants, I want more. Actually, the shatranj variants I've posted here pretty much give an overview of the territory set out in MS and 2Large. But there are obviously more games in the mix. For example, the Sliding General, a 2-step queen, is a very interesting piece that is not [yet] used. And the knight-ferz and knight-wazir are languishing in obscurity; yet they are very dynamic pieces, each worth about a rook, with interesting abilities and limitations. Perhaps there is a game hiding between Grand Shatranj and ABS that someone [maybe even you or I] will find and post. In the meantime, I'm still looking at more short range jumpers; can Lemurian Shatranj be far behind?

Christine Bagley-Jones wrote on Wed, Jul 12, 2006 12:17 AM UTC:Excellent ★★★★★
you got enough variants going here Joe? he he, well another great looking 'shatranj' type game, terrific idea with 'jumpingking'! + direction changing pieces very interesting!

💡📝Joe Joyce wrote on Tue, May 16, 2006 10:35 PM UTC:
Thank you very much for the comment, Mike, and I hope to be able to live up
to the compliment. After I accidentally designed Modern Shatranj, I got
interested in short-range and jumping pieces, and eventually realized I
had a series of games that could feature pretty much nothing but
short-range jumpers. And that seemed unusual enough to be worth pursuit.
Great Shatranj was the 1st, with no (rooks optional) piece moving over 2
squares, but some 'new' combo pieces; then Grand Shatranj, featuring
2-step pieces moving up to 4 squares, and 1 more 'new' combo piece (the
Squire/Jumping General/Mammoth). Finally, I found the idea of bent riders
irresistable, and decided to make a game with almost super-powered short
range pieces. The zigzag general comes close, and it may actually be a new
piece. All the 2-step pieces would be quite comfortable on larger boards,
I plan to continue exploring short and medium range pieces for a while.
I'm looking at some 3-square movers and contemplating what might go 5 or
6 squares. There's gotta be some opportunities for genuine new pieces

An excellent concept game and I think it will be quite playable. Joe's
whole series of Shatranj variants are fascinating. The varying power
levels of short and medium range pieces with few or no long range pieces
make for something quite different. 

This particular variant with its direction changing moves reminds me of

Great, Tony! Three pages, with 5 presets, are now waiting for approval.

David, thank you very much.

Thanks for the comment, Namik. The game you propose could be quite interesting, ABS vs Sym. As it stands, each side has 10 pawns, but Symchess has 12 pieces to ABS' 10. I might suggest throwing in a couple colorbound 1 or 2 square movers for ABS, 'FAD' leapers. They slide 1 diagonally or jump 2 orthogonally or diagonally, landing on every square of their color within 2. Just how closely the sides are matched is an interesting question. While piece values for Sym are pretty well determined, I know of no info on values of most of the (brand new?) ABS pieces. The zigzag general in particular is a deliberately overpowered piece restricted by its short range, as to a lesser extent are the twisted and flexible knights. So it's sort of 10x10 Chess with Very Different Armies. Very possibly worth doing.

Namik Zade wrote on Tue, May 2, 2006 11:59 AM UTC:Good ★★★★
Very nice. I think 'Atlantean Barroom Shatranj vs Symchess' preset will be interesting too.

Tony Quintanilla wrote on Tue, May 2, 2006 04:42 AM UTC:
Joe, you are correct. The preset on your link is perfect, but it is not separately listed. The preset is not posted as a separate page with a green icon. Only individually posted pages can be listed, whether member or editor created. Someone looking for a preset in the preset lists could then find it. As it is, one can only find your preset by looking at the game page or the comments on the game page. That's ok too. A separate page is not necessary, but you had asked about listing your preset. For that, a posted page is needed. That's an extra step that requires an editor at this time (that's the slow part!).

Hi, Tony:

I don't understand what you mean about having to make pages for the presets. Aren't their pages just like the following:

Atlantean Barroom Shatranj which is the url for Atlantean Barroom Shatranj? I'd love for people to actually know I made the presets. I suppose it's questions like these that demonstrate why I'm not an editor...

Tony Quintanilla wrote on Tue, May 2, 2006 12:15 AM UTC:
Joe, yes, the preset links work just fine, but I did not realize they were there. Could I suggest a note below the images noting the link to the presets? To list them as presets, we'll have to post separate pages for the presets. -- Tony.
