What a cool tool ... for others who read this and want to know ... if you edit the message you will need to put the & lt and & gt back in as the code is translated each time it is posted so in Fencer's post if edited and updated without the resubsitution it would look like this :)

Don't use absolute URLs. Something like this works for everyone:

Now all Fencer has to do is teach us how to actually get the & lt and & gt (sans spaces) to write to the page without being changed into < and > :)

If anyone is interested, check out the following game:

http://brainking.com/game/ArchivedGame?g=165709

Basically, we ended up in a situation where the kings were next to each other. The only way to win the game in situations like this is to force the opponent king into a situation where you can blow a piece up that blows their king up without blowing yours up...

Thanks to slmoore25 for a great game and the permission to post the game for others to learn from!

jestone, you wrote :

Do you think that these values are also applicable for Loop Chess? Otherwise, which are values for this last game?

By looking on the Web, I found the other proposed values :
Q=4, N=2, R=2, B=2, P=1

Anybody can say to me what we can retain of it?

It's an interesting point. With plenty of pieces still on the board I think two checks is usually good value for a piece. One check can go either way so involves delicacy of judgement.

Subjekt: new name for this game and anti-chess
this game and anti-chess seem like an all out front dedicated to a main purpose that often involves sacrificing a piece. For example, a player may knowingly take the pawn in front of a king, which puts the queen into danger from the opponents queen, but it is worth one check. My proposal is that these games be called something like Kamikaze chess or something.

Subjekt: hoisted by my own petard
Sometimes we learn from our mistakes, & sometimes we don't even learn from our sucesses. Observe this recent win of mine:
#109725. Nice smothered mate, no?

But then later, came this: #101783. No need to finish that. Sometimes I wonder where my brain has gone!

At least it brought to mind the title of this little note, explained below.

“To be hoist by one's own petard,” a now proverbial phrase apparently originating with Shakespeare's Hamlet (around 1604) not long after the word entered English (around 1598), means “to blow oneself up with one's own bomb, be undone by one's own devices.”

Subjekt: Relative piece values
I have been informed that Loop chess as played here, is similar to a 4-player variant called bughouse chess. Upon doing a Google search on that latter topic, I found a site that discussed some interesting ideas that might apply to Loop. I copy them here & hope they will be of some relevance to we Loop players...

Piece Values:

Most serious chess players are familiar with the Piece Value Table: Q=9, R=5, B and N=3, P=1. In bughouse however, the values are completely different. While there is no general consensus on bughouse values, here is an approximation.

Q=10, N=7, R=4, B=2, P=1

The knight and queen rule the bughouse chessboard. The queen often can be placed into a position with mate. The knight is useful as well because it can check from a distance and not be blocked. Many bughouse mating attacks begin with a sacrifice on KB7 followed by a knight check. For example, after 1.e4 e5 2.d4 exd4 3.Nf3 Nc6 4.Bc4 Bc5 5.Bxf7+ Kxf7 6.Ng5+ all white needs is a queen for f7 and black will get mated. The bishops value is seriously diminished, as it often performs no better than a pawn, and sometimes not even as well. The pawns promotion abilities may in some positions be worth significantly more than a bishop.

Subjekt: Some analysis to even up this game
To all -

Dmitri King previously mentioned that I had suggested a way to even up this game by having 2 'Queen' Maharajah's (able to be captured) and 1 'KING' Maharajah (must be checkmated like a King to win). Here are some more particulars on that.

I think that it SHOULD be obvious to ALL experienced players that Black should win by force in less than 30 moves with the current rules in Maharajah Chess. (Forced mate in 30 or less.) The fact that black could simply FORCE a minimum of a draw by moving a Knight back and forth while white wonders around aimlessly is also a telling factor. But of course, it would not make sense for black to settle for a draw. It is just a BIG tipoff to black's advantage.

Here's a simplified analysis of the value of pieces to make this into a reasonably even game for both sides. In regular chess, the pieces are assigned the following point values: Queen 9 points, Rook 5 points, Bishop & Knight 3 points, and Pawns 1 point.

In my opinion, a piece that can move like a queen and knight all by itself is somewhat more valueable than a queen and knight separately, simply because all alone, it covers ALL areas of a 5x5 zone if it is 2 spaces away from an edge and could quickly and easily mate a king even with a couple of other minor pieces around. So if a Queen and Knight separately are worth 12 points, I'll assign the regular Maharajah piece a value of 14 points. BUT...and a BIG BUT, the fact that this piece is like a King and cannot be captured reduces his value quite a bit. I'll say by 3 points. So I would say that the white's current Majahara piece is worth about 11 points.

Now if you add up the ENTIRE side of black's pieces, you come up with 40 points (counting the King as 1 point). Now I would say that you should reduce the value of each pawn by 1/2 point because they cannot promote to a queen or other piece. The reduction is 4 points there. So the total 'value' of black's pieces is 36 points.

So black is playing with a 36-11 piece value advantage. It's like playing over THREE queens down!!! NOW, you know why black has such an overwhelming advantage!!!!!

I have seen several suggestions here and NONE of them are enough to even up the sides. Some have said the following: give white the loop possibility, give him 4 pawns, give him 8 pawns, give him the Knight+ moves, or even give him ANOTHER Majahara! NONE of these is NEARLY enough. Even TWO Majahara's would be a BIG disadvantage. By BIG, I mean amongst experts (2000+ FIDE or USCF rating), black would win 95+% of the time. (Probably more like 99%+)

Here's an analysis of what I think that it would take to even the sides up. First I'll give some definitions:
Majahara Queen = Majahara piece that CAN be lost but still moves like a queen and knight. (As shown above, the value of this piece is ABOUT 14 points.)
Majahara King = Piece like now that CANNOT be lost or moved into check. (The current Maharajah piece valued above at about 11 points.)

Based on this, here is what should even up the sides. Have 2 'Queen' Maharajah pieces and 1 'King' Maharajah piece for white. The total value of these pieces would be: 14 + 14 + 11 = 39 points.

Now, black MUST be able to promote his pawns if he reaches the back rank so as to bring the value of his pieces back to the usual opening point value in regular chess of 40 points.

With a 40-39 point count on pieces, there should be some VERY interesting games where White could perhaps sacrifice one or two Queen Maharajah's to pick off a slew of black pieces and ultimately move in for a mate using the King Maharajah. Or black could maticulously and carefully march his pawns down to promote them so that he can fight off and capture the powerful Queen Maharajah's so that he can finally mate the King Maharajah. I foresee that black would need to queen 2 or even 3 or more pawns so that he could finally move in and trap the King Maharajah or pick off the Queen Maharajah's as needed.

THAT would be VERY interesting and I could see some VERY long and drawn out battles amongst high-level players, perhaps lasting 100 moves or more!!!

I'd be curious to hear everyone's thoughts on this.

Subjekt: blacks overwhelming advantage
I've played a few games of this now. It does appear there is at least one "perfect" game for black. Of the suggestions below, the only ones that might address the existance of a relatively simple perfect game are the 1-3 move and the addition of extra maharaj pieces, IMO. I like both ideas but I think you'd have to play them out to see if it worked in practice.

I think you might need to reread the rules. Basically, when you or an opponent takes a piece all the pieces on adjacent squares (except pawns) belonging to both sides are also taken in the "atomic" explosion. Awesome really!

Subjekt: Re: maharajah chess
Good to see the discussion has again begun. Most of the suggestions (he says pushing his chest out boasting :) ) were probably mine. Each has some merit but my favourite is the extra extended knight 3-1L move. As DK says, black can play such that all pieces protect each other, but what it does do is allow white to treaten the black King without interference from a string of pawns. Without playing the game I am not sure if this sufficient force to prise open a black defence but think it is really worth a try.

And on another matter, I would like to join the queue to play black against Uil's white Maharajah :)

10. dubna 2003, 00:56:09
Dmitri King 
Subjekt: maharajah chess
I saw an idea where someone suggested the maharajah be given extra moves, those of a knight that can move in a 3-1 L. I do not believe this will change things a whole lot. The problem is, white cannot make any kind of attack on a defended piece, since it has no piece to back up a capture with. It is not difficult for black to keep all his pieces defended. Losing as black is inexcusable. Heck, losing a PIECE as black is inexcusable. I lost a rook in one game only because I failed to notice it was threatened. That is a pure careless error, it was not the result of clever play by my opponent.

Regarding what one person said about having 35 moves be a draw and 50 be a loss. That also does not work. The game appears to be a forced win for black in approximately 20 moves, as was demonstrated to me by a player whose name I cannot remember. It might have been whisperz.

The only way ot make this a game (right now it hardly qualifies as one, given the tremendous advantage that black has) is to add more pieces for white. Gary Barnes suggested having THREE maharajah pieces, one of them a King maharajah and theo ther two Queen maharajahs. The queen ones can be lost, but not the King. Even then black may have an advantage.

Uil-- I saw that you posted that you are undewfeated as white (although it seems like you have since picked up one loss). This is surprising, but it doesn;t prove much. It had to be careless play by your opponents that resulted in all those wins as white.

I am willing to guarantee that I will win this game as blakc against ANYONE. I am not even willing to do that in pente or Keryo pente, despite not having lost once yet as player 1 in either game.

The game of maharajah may have history, but it need to be changed. If the purists are bothered by this, then call it something different. But as it stands now, I cannot see any reason to play maharajah chess.
