Shortly after this particular game began, the Raumschach preset was corrected to show alternate colors for the squares on the second and fourth boards. See also L. Lynn Smith's Zillions file for Monster 3D Chess. In that 6x6x6 variant the Unicorn moves as in classic Raumschach, while the colorbound Hippogriff 'leaps to the opposite corner of a 2x2x3 area'.Game: Universal Chess Log: judgmentality-makov333-2009-248-434 David Paulowich wrote on 2009-09-13Spotted Gryphon This colorbound piece moves like a ferz and may also continue outward as a dabbabah-rider, until it captures a piece or is blocked from further leaping. It can reach all squares of the same color that a Gryphon can, with the advantage that its movement can only be blocked on those squares. See my Rose Chess page for a Chainsaw (Dragon) movement diagram.Game: Universal Chess Log: judgmentality-sissa-2009-244-339 David Paulowich wrote on 2009-09-05White overlooked 1.Rose c1-b3-c5-e6-g5 mate.

This game design requires the White Elephants to start on ranks one and two, in order to place them on squares of opposite color from the White Ferz. If, on the other hand, the game started with Elephants on the first and tenth ranks, then the fifth rank would be dominated by White Elephants and the sixth rank by Black Elephants. That initial setup might make it more difficult for the players to advance their pawns into enemy territory - and result in more drawn games.Game: Shogi Log: hambledon-sdc.stats-2008-256-740 David Paulowich wrote on 2008-09-18Promotion is immediate, after making a normal move that ends (or begins) in the promotion zone.

Why bump the colorbound pieces up 25 points? The Ferz is a handy little piece, worth a solid 150 points on a 10x10 board, plus a 25 point bonus for promoting (just like the Pawn). While the Alibaba may be worth not much more than 200 points, the Elephant should be nearly as valuable in the endgame, when there are few pieces on the board. Ralph Betza once estimated the combined Alfilrider and Dabbabahrider piece as worth no more than a Knight on an 8x8 board. Instead of generating pages of pseudomathematics here, I will just list some reasons for liking these pieces: the War Elephant can force a stalemate victory against a lone King, while King and (ordinary) Elephant can actually draw against five War Elephants, provided they all travel on squares of the opposite color to the Elephant.Game: Chieftain Chess II Log: david_64-joejoyce-2008-91-546 David Paulowich wrote on 2008-07-31Knight = 300, Guard = 300, Shaman = 360, Hero = 450 are my latest estimates for this 16x12 board. I am giving the three-steppers lower values than in Opulent Lemurian Shatranj, as I feel that the much larger board and multiple moves per turn cause a 'leveling out' of the piece values. The Chieftain (giving the player an extra move) is worth at least two Heroes.Game: Rose Chess XII Log: david_64-sissa-2008-194-848 David Paulowich wrote on 2008-07-16 This movement diagram uses hollow squares for the War Machine and X's for the War Elephant (not used in this variant).

It has been used recently with the name 'Lion' in games by David Paulowich. This piece may leap either 2 or 3 squares horizontally or vertically, or may step a single space digonally. This piece stays on squares of the same color except when it makes the somewhat awkward (0, 3) leap. The ScoutThe scout may step one square horizontally or vertically, or leap exactly three squares horizontally or vertically. Also, a Scout that has not moved yet this game has the added ability to move (once) like a Knight. Like the Knight, it is forced to change the color of the square it occupies with each move. Piece diagrams and descriptions taken from Greg Strong's Hubbub. The Lion is used in Unicorn Great Chess. The 'War Machine' in Rose Chess XII moves like a Scout, but without 'the added ability to move (once) like a Knight'.Game: Rose Chess XII Log: sherman101-cvgameroom-2008-19-956 David Paulowich wrote on 2008-01-28The Notes section on my Unicorn Great Chess page has a link to the preset: 'Computer Play: Fergus Duniho was kind enough to playtest this game with me in 2001 and create a PBM preset here.'

I do recall a wild position 28 moves into my game with Gary Gifford, which left me with Cannon and Elephant vs. Knight.

This prompted me to looks up some Shogi references: http://www.delorie.com/gnu/docs/gnushogi/gnushogi_18.html There is no special castling move in shogi. The term 'castle' is used in shogi to denote a defensive formation consisting of (usually) three generals which protect the king.

Permit me to ramble on for a while here. Suppose a master slides the White Bishop f1-b5 in a Ruy Lopez. According to the strict 'touch-move rules' FIDE passed in the 1930s, that Bishop has touched the squares e2, d3, c4, b5 and Black has the right to pick any one of those four squares and force White to move to that square. Tournament directors had to ignore that particular rule, as many high level players continued to slide their pieces across the board. Since then, players have tended to ignore how the Bishop gets from f1 to b5. And the younger players grew up on: click f1, click b5, click SEND MOVE. Which raises a tricky question: Are we enforcing 'touch-move rules' in this tournament? To be specific, if I attempt an illegal move, can my opponent demand that I then make a legal move with the same piece?Game: Catapults of Troy Log: antoinefourriere-cvgameroom-2005-158-780 David Paulowich wrote on 2007-09-30Black's Pawn launch on move 19 passes over multiple pieces.

The Wazir has a move of length 1.0, the Ferz has a move of length 1.4 ( the square root of two ).' Regarding Betza's statement, in the endgame a piece may need to move quickly from (b2) to (h8).

And invent positions like this one: WHITE (to move and win) King(a3), Cannon(g1), Bison (g7) BLACK King(b1), Cannon(a1) After 1.CxC KxC the Bison will force mate in 3 more moves: g7-d6-f3-c4. If Black fails to capture the White Cannon, then the three White pieces will eventually force checkmate. And so the position after 1.CxC KxC also serves as an example of a forced mate in 3 by a single Falcon. In general, a pair of Falcons should be able to mate a lone King. Even a pair of Knights can force a lone King into a corner and stalemate it - but they lack the ability to force checkmate.David Paulowich wrote on 2007-04-111. c2-c4 1... n b8-c6 2. c4-c5 2... n c6-e5 3. c5-c6 3... n e5-g6 4. c6-b7 // PxP 4... n i8-h6 5. b7-a8; Q-a8 I just ran this sample game to verify that Pawns promote to Queens (and presumably other pieces) in this rules enforcing preset.

First: 6 moves for White and 6 'mirror' moves for Black. Next 6 more moves for White, representing his goals for the opening phase of the game. Points of Interest: Cannons are attacking Pawns in the initial setup, so precautions need to be taken before the Knights are moved. The Elephants on the h-file now defend the j-file Pawns. On the other side of the board ... Cannon(a10) x Pawn(a3) can be met by Elephant c4-a4, followed by Knight d4-b5. The best move for the trapped Cannon is: sacrifice itself for the Pawn(c3). And what about that Ferz on f2? Will it serve any purpose in the game besides defending the Pawn on g3? One plan for the endgame is to move a Cannon to f1 and 'fire over the Ferz' to control 8 empty squares on the f-file. The Black King and one Elephant must stop on the f-file whenever they cross the board, which is a major headache.Game: Shatranj Kamil (64) Log: judgmentality-cvgameroom-2007-69-586 David Paulowich wrote on 2007-03-11Jeremy, Checking the [Exclude Pieces not in Setup:] box will spare the players (and onlookers) the delays involved in loading those 1200(?) images.

I plan on taking at least 36 hours per move, in order to justice to this complex game. I agree with the rule allowing a King to move into check, stay in check, or be exposed to a discovered check during the sequence of moves that make up a single turn. For example, in our last game - Black King captures the White Knightrider [placing the Black King in check again] followed by Black Queen captures White Queen - would have saved the game, if only you had been allowed enough moves to clear a path for the Black Queen.David Paulowich wrote on 2007-02-11Apparently this board is still set at 18 units wide (a - r). This is causing problems with the display, especially when it is Black's turn to move. I propose using these rules: first turn 4/8 moves, progressive rules for later turns even a single capture removes the giant ferz even a single check endangers the giant wazir, and must be countered to avoid mate.Game: Tiling Rider Chess Log: judgmentality-david_64-2007-29-031 David Paulowich wrote on 2007-02-09Yes, if you can force my Queen to stop on the 11th and 12th ranks, then there is no checkmate. I took the Knightrider mate you were kind enough to point out to me and adapted it to a Knightrider support of a Queen mate. Note that my Rook (next to my King) has an important role: preventing you from playing a 1-move Knightrider mate on the 'giant square' directly in front of the Rook. WILD GUESS at piece values: Ferz=1, Wazir=1, Guard=2, Knight=3. Clearly Knightriders and Queens are powerful attacking pieces. I think that Rooks are stronger than Bishops (no surprise there), but a solitary Ferz can race forward at a steady 2 squares per move and provide the forward line of defense we now know to be crucial in this game. Even with elongated moves, a solitary Wazir advances 2+1+1+2+1+1. How big is the increase in value when a player forms an aggregates? Well, a Queen may be worth as much as 3 Wazirs plus 3 Knights (that can never form a Rook or a Knightrider). Bad luck for a player to get reduced to 3 of one piece.David Paulowich wrote on 2007-02-09Turn 10 checkmate, because the White Guards on k13 and k14 can only be captured by giant pieces. If the the Black King captures the White Queen, then 3 more moves are required to eliminate all Knight checks. If the the Black King captures the White Knightrider, then 3 more moves are required: h13-h11; g13-h12; [Black Queen captures White Queen]. My hypothetical comments two days ago have nothing to do with this mate. Many thanks for the game!David Paulowich wrote on 2007-02-07'Square Tiling Rider Shatranj' is a perfectly good name for the 16x16 game - it is still your variant, after all. Looking forward to a game with you - but I may wait until next week to begin. I am in a kind of opposite situation to you, with MIR CHESS 36 having started out as the simple idea of an 8x8 version of SHAKO, but my refinement MIR CHESS 32 added several original touches. 'My heart says yes, but my mind says no.' Trust your mind - note how easy it is to move an aggregate to a location adjacent to your opponent's royal piece, so any 'jump off the aggregate bus' rule would allow (part of) the royal piece to be captured in the same game turn.David Paulowich wrote on 2007-02-07I am tempted to place a nonroyal Giant Ferz on k1, k2, l1, l2 (also k15, k16, l15, l16) and then remove the a1-a16 and b1-b16 columns from the board. This results in a 16x16 variant giving each player 14 copies of each small piece. The (NEW) a1 to p16 diagonal will be shades of blue - which matches the 'black' squares in standard 8x8 chess. The (NEW) locations of the royal giants match that in the 8x8 Shatranj setup. I am unsure which player actually has an advantage under my proposed 4/8 moves rule. That sounds like fun!David Paulowich wrote on 2007-02-02You asked for comments: Your variant reminds me slightly of highly symmetric 9x9 variants, but in fact this 18x18 setup has different pieces on the the 'i' and 'j' files - and the 13th row matches the 3rd row while the 12th row matches the 4th row. This lack of symmetry seems to be a small advantage for Black. Here is a rules change to help Black some more in future games. TURN ONE: White makes exactly 4 moves and Black makes exactly 8 moves. TURN TWO: regular rules apply, with White moving up to 9 times and Black moving up to once more than White.Game: Grand Rider Chess Log: brainburner-judgmentality-2007-29-748 David Paulowich wrote on 2007-02-02I suppose Black moved a Berolina Pawn on move 5.

Only actual play will determine if I have successfully merged two variants into one enjoyable game. As for the question Joe asked at the end of this game, I suspect that the General is not strong enough to beat a Knight in the endgame. This seems reasonable, as the endgame K+R versus K+N is usually a draw. In fact, I cannot find a winning strategy for King and Dragon Horse versus King and Knight. I set up Zillions to play this endgame against itself on a slow setting, with no progress being made after 60 moves. That is somewhat shocking, as I consider the Dragon Horse to be worth a pair of Knights.

So what have I learned this time around? STRATEGY: the Half-Duck is worth 50% more than the Short Rook, making it too valuable to risk trading. I should have used my Short Rooks aggressively and perhaps traded them for the Charging Knights. TACTICS: If Black plays 29...CH b2-b1(check) 30.CR d2-e1 the Chancellor will have to run away, losing a tempo. Black saw the diagonal move 30 at the last moment, because he had been thinking of the CR as a ordinary Rook. What should Black have played earlier? After 28...WR f7-f6 29.CO f4-d3 the Chancellor will still have to run away. After 28...HD e7-f6 29.CO f4-g6 Black has saved his Half-Duck from capture, but White seems to have a mating attack similar to the one that ended this game.

Ra1-a5 should force a draw. White's Elephant pair is very strong in the center of the board and Black has to worry about the weak Black Pawn (a7). Christine, now you know which endgame to avoid. You needed to force a trade of the light-square Elephants early in the game - then your General could have exploited the colorboundness of the lone White Elephant. If that was not possible, you could try to trade your Elephant for two White Pawns. Good winning chances for Black - also some losing chances(!)Game: Mitosis Chess Log: mageofmaple-cvgameroom-2005-156-774 David Paulowich wrote on 2005-07-02WARNING! any attempt to move a piece from f9 or d9 results in: <p>Syntax Error on line 161 <p>The function t has not been defined.Game: Modern Shatranj Log: joejoyce-zcherryz-2005-154-231 David Paulowich wrote on 2005-06-29http://www.chessvariants.org/d.betza/pieceval/fig2key.html <p>gives some of Betza's thoughts on piece values. My piece values are intended for the late endgame, when a Rook will dominate the board. But nothing is carved in stone - many writers reduce the Rook's value to 14 or so (4.66 Pawns). Feel free to quote my numbers - but I reserve the right to change my mind in the future. How would I rate the pair of MS elephants? I mistrust colorbound pieces. In fact, I have made a career out of trading a Bishop for a Knight in the opening and using my 'deadly Knight pair' in the middle game. Also I generally get good results in one Knight versus one Bishop endgames. <p>Here are some simple endgames. FIRST: K+N vs K+R is usually a draw, except when the White King happens to be on the edge of the board. Perhaps there may also be a chance for a stalemate victory in a Shatranj variant. SECOND: consider the position WHITE K(b2) and E(e5), BLACK K(d3) and G(c4). After White moves the Elephant, the Black General will check on c3, pushing the White King to the edge of the board. I really don't know if there is a forced mate here - Zillions can be useful for testing endgame positions. THIRD: K+E+E vs K+G+P pits a 16 point force against a 15 point force. But Black may be able to advance the Pawn until White is forced to trade an Elephant for it, leading to the sort of endgame I dealt with in the previous note. Generals appear to be much stronger than Elephants.David Paulowich wrote on 2005-06-27Pawn=3, Elephant=8, Knight=9, General=12, Rook=15 is my 'best guess' for the values of the pieces. Back in 1996 Ralph Betza said your General (also called Commoner) was no stronger than the Knight, but he later corrected that mistake. Setting the King itself at 2.5 x 3 = 7.5 points would only make sense if you assign a large penalty for being vulnerable to checks. Elephants and Knights are valuable on a crowded board, but less so in endgames where their ability to leap is mostly irrelevant. <p>I believe I can offer more than just a guess as to what constitutes suffient mating force against a lone King on the 8x8 board. King and one General will suffice, as will King and two Elephants. King and two Knights can slowly force a stalemate victory. Compare the forced mate in sixty moves (or so) in some FIDE endgames where King and two Knights first blockade the lone enemy Pawn, then force the enemy King into a corner, then move in and 'stalemate' the King. After the Pawn makes a move or two, one of the Knights shifts from 'stalemate' to checkmate.Game: Opulent Chess Log: mageofmaple-cvgameroom-2005-122-773 David Paulowich wrote on 2005-05-04Greg: the Rules Button for this game links to Wildebeest Chess.Game: Shatranj Log: joejoyce-rlavieri2003-2005-99-890 David Paulowich wrote on 2005-04-23Assuming that you do not promote a Pawn to a Ferz, then your variant is different enough that you should write it up as a stand-alone variant. I suggest you first check out my Shatranj Kamil (64), soon to be a last minute entry in the 10-Contest. I will have a lot to say about bare king loss, and other rules.

That variant has two 'Dragons' that move like Elephants or Counsellors, plus a single 'Champion' that moves like a Counsellor or forward orthogonally (compare the Silver General in Shogi). Pawns promote to a variety of pieces. Also, I am currently putting the finishing touches on Shatranj Kamil (64), with 18 pieces in each army on an 8x8 board, including a brand new version of the Elephant. Pawns promote to Silver Generals.Game: Kamikaze Mortal Shogi Log: mageofmaple-fergus-2005-89-723 David Paulowich wrote on 2005-04-21'In the first story he was called Galloway.

Nothing else.David Paulowich wrote on 2004-12-04This variant expands on an idea from the Kibitzer article 'Bring Back Free Castling!' by Tim Harding. A king may free castle with either the nearest rook on its left side or the nearest rook on its right side. When the players drop the kings on the a-file and the rooks on the b-file and i-file, for example, the only possible castling move is switching the king and the b-file rook. The 'outside rook' can never take part in castling. This rule could even be used in variants with more than two rooks for eack player. More often the rooks will be on opposite sides of the kings. Suppose White has K(c1), R(a1), R(j1) and none of these pieces have yet moved in the game. Let Black have K(e3) and Q(e4). White to move can free castle only by moving the king to d1, e1, f1, or g1. Since the Black queen attacks h1, the king can neither end its move on h1 nor pass through that square to i1 or j1. The rook on j1 can move in free castling to c1 or to any other square between c1 and the one the king ended its move on.Game: Wormhole Chess Log: carlos-cvgameroom-2004-295-796 David Paulowich wrote on 2004-12-0420. g3-h3;-g3 <p>20... g4-c4;-g4 // Ch x P <p>I used to play only three games at a time and made use of my Omega Chess set.

Bishops must be placed on opposite color squares. Each player must also copy the opponent's drops, placing pieces on the same files. This process will take three game moves for each side.Game: Wormhole Chess Log: carlos-cvgameroom-2004-295-796 David Paulowich wrote on 2004-12-03I am happy to allow one 'take-back' per game.

As pointed out in my previous comment, the Knight on k6 is defended by the Black Chancellor on k8. I believe that the first time in this game a Chancellor has actually moved two squares in a straight line was on Black's move 37.David Paulowich wrote on 2004-11-21http://www.chessvariants.org/large.dir/contest/kings-court.html <p>is the first web page I consulted before signing up for this game. The chancellor diagram shows a 'Q2N' move - it can move one or two squares like a queen or make a normal knight move. This preset uses crowned knight symbols for the chancellors, which might confuse some players. Especially if they are thinking about the different definition of the chancellor given in the (lesser) Kings Court variant on the commercial site. <p>The KingGame: Fischer Random Chess Log: math-cvgameroom-2004-313-900 David Paulowich wrote on 2004-11-15What happened to the record of moves 8-9-10?

This 80 square variant is so 'trappy' that the ChessV program has twice tossed away material against me in the opening.

It all comes down to search depth. In some lines the White Unicorn can capture the Rook on i8, but it will be trapped after ... Knight j7-h6. These lines may register as 'false victories' in computer analysis. Running Zillions-Zillions test games at 3 minutes per moves can be extremely effective, but it it cannot rescue a game from human error. After Zillions came up with 8. Bishop e2 - j7, Pawn h6 x i5 9. Bishop j7 x i8, Knight f7 - h6 it was clear that I had tied myself up in knots trying to hang onto the extra Pawn. I chose to capture the Bishop and gamble on my opponent missing the best continuation, a strategy which has served me well over the years. Not this time! Congratulatons to ChessV and its creator.David Paulowich wrote on 2004-10-10'Any Pawn may make an initial double move. Whenever a double move takes a Pawn to a space horizontally adjacent to an enemy Pawn, the enemy Pawn may take it by en passant on the next turn. On reaching the last rank, a Pawn promotes to a Chancellor, Queen, or Unicorn, but not to any lesser piece.' This should replace the definition of a Pawn in the Lions and Unicorns variant, which lacks the more complex initial setup of Unicorn Great Chess. Another suggestion: both of these variants could simply link to themselves when you click on the RULES button. At present they link to a Great Chess rules page, a legacy of the Great Chess preset they were based on.David Paulowich wrote on 2004-10-09In this second game of Lions and Unicorns Chess, White is ChessV and Black is ZPaulowich (a combination of me and Zillions 1.3.1). The Unicorn moves like a Bishop or a Nightrider, while 'Lion' is another name for Ralph Betza's 'Half-Duck'. My three games on this site are using an obsolete email account that expires on October 31. I don't even have an email program on my primary computer and hope to continue playing in November without this emailing moves feature.Game: Lions and Unicorns Chess Log: MageOfMaple-paulo-2004-268-719 David Paulowich wrote on 2004-10-081.

My previous note showed the loss of tempi resulting from Black playing Lion a8-a6 one move later (move 6). So the line in that note is a positional blunder, at least at the master level. And the line played in our game ended in a tactical blunder. Hard to spot exactly when it happened, especially when I am running a weaker chess program. <p>I am happy to take the Black pieces in Game 2, as long as you are aware that it may terminate on October 31. I have no intention of changing my personalid file here to include my new email address. I will post more details on that PBM page. David Paulowich wrote on 2004-10-03My 533 MHz computer (AMD K6-2) runs Zillions 1.3.1 at 3 minutes per move, for both sides. After watching TV for an hour, I can return and examine one possible future for the game. This is more important to me than finding a theoretical 'best move', which I would most likely disagree with anyway. Also, I prepared an opening trap. Black was supposed to play: 6 ... Lion j8 - j6 7. Lion j4 x j6, Pawn i7 x j6 8. Pawn b2 - b4, Lion a5 - a8 9. Pawn b4 - b5, Knight c6 - e7 10. Lion a1 - a3, Knight e7 - g6 leaving White with a positional advantage. <p>Something went very wrong and now Black is sacrificing pieces to avoid checkmate. I can take credit for the opening moves, as well as the decision to capture Black's Knight on move 13, instead of the more valuable Bishop. But Zillions is giving a massive boost to my tactical strength. I am in danger of turning into a trained monkey, pushing buttons on the computer and staring at the blinking lights with no comprehension.Game: Pocket Mutation Chess Log: mikenels-paulo-2004-248-816 David Paulowich wrote on 2004-09-05And Rule 4 in this version is cut back to: <p>'If the piece put into the pocket was removed from its owner's eighth rank, then it promotes to the next higher value class.

Currently I am busy working on changing the rules file 'alf-capablancaschess.zrf' into 'alf-lions_and_unicorns.zrf'. That's right, this is a draft set of rules placing Chancellors, Lions, and Unicorns on an 80 square board. This time around I am going to prepare a brand new web page before the ZRF files and PBM presets go up on the internet.
