I'm going to play a game or two of this game on game courier if possible, I notice your comments about this game Kevin, if you want a game you can send me invite, i'll play the black and green side!!

Link is here, i'm giving the link because it is spelt 'chatarunga', not the usual way.

Of course, if we play this game, we are playing with double mate rules that is on this page :)

Oh, if anyone else wants a game, send me an invite, i'll play the black green pieces.

@ Greg:

Here's another CV rules page, this time by a different author than myself, that I've found that currently has had its text formatting somewhat messed up, again perhaps due to a change in CVP's database formatting some time back.

This looks like a fabulous game that would seldom be dull. I don't know if one side can force a win or even a significant advantage straight from the opening, but as long as this is a mystery it adds to the charm of the variant. The 2 games between the author and Joe Joyce, circa 2011, were illuminating for me. These were played using the non-rule enforcing preset "4-Handed Chaturanga" that is still currently used to handle any 4 army (though 2 player) Chaturanga variant on Game Courier, it seems.

My tentative estimates for the piece values of this variant would be: S=0.625; P=1; N=3.5; R=5.5 and the fighting value of K=4 (though naturally it cannot be traded). Bear in mind that years ago ZoG estimated the value of an alfil [an S in this variant] on an 8x8 board to be about 1.16, or almost twice what I have it as. I reached that value by taking an initial value for S of (N-1)/8 - for being thrice binded - and then multiplying that by 2 (as a bonus for usually being a speedier short-range leaper than the otherwise somewhat similar N) to get my final value for S.

[edit: some implications of the rules of this particular variant are not totally obvious to me, though I believe I understand them: Firstly, I asked myself, can a player ever capture one of his own pieces (aside from under the special case of the meeting of the 4 ships rule)? That is, can a piece that belongs to his army of the other colour be captured by a piece of the colour that he is moving, e.g. can, say, a yellow king ever capture a red pawn? The answer seems to be clearly 'no'. For in the rules there is stated: "The black armies pieces and pawns can be captured by the yellow and red pieces". Nothing is mentioned about green being able to capture black's pawns and pieces. That said, a similar question I had about the rules was whether, say, a yellow piece can ever be giving check to the player's other (red) king, and the answer again seems to be clearly 'no' (just as a yellow piece or pawn cannot capture a red one). Lastly, perhaps the most vexing question I had was if, say, the red & yellow kings could ever legally be on adjacent squares. In the rules there is stated: "A king also cannot move to a square that is being attacked by an enemy piece, even if that enemy piece's king is in checkmate". There is nothing stated about a king moving to a square attacked by a friendly king (the quoted statement also in a similar way reinforces my conclusion in the previous paragraph). Thus it seems clear that indeed the red & yellow kings could legally be on adjacent squares.]
