THE GREATEST THING SINCE BOBBY FISCHER!

Sorry I couldn't make 4 colors. Someone please upload a photo with green and brown on the right.

READ TILL THE END IF YOU'VE A BRAIN IN YOUR SKULL!

I strongly believe it would be worthwhile for Chess.com to add a real cooperative game feature to the App. There should be two boards attached side by side. IJKLMNOP squares will be added after the H squares. Four colors and four players. [White & green vs black & brown.] Top two are allied and bottom two are allied. Piece setup and most game rules are the same as in regular chess. Move order: bottom left, bottom right, top left, top right.

If you lose your king you still play on with all your pieces so long as your allies' king is still on the board! There are countless new tactics and strategies available in this format, and the fun is tenfold for the co-op. You can hide your king in your allies' fort and go all out offensively while he plays defence, or you can launch a devastating attack together. You can castle near your ally in middle of the board, or on opposite sides. Like I've already said, if in check, you don't have to save your king if your allies' king is still alive. [You can deliver checkmate with your king.] If the teams' 2nd king is in check both players are forced to defend it by whatever means they have. He who goes first doesn't have to, if the second player can. Time is counted for the team, not the player. You can also message your ally what move to play. To suggest a move to your ally you simply press the squares and they get to see it as a suggestion. There could be a limit to how many suggestions are allowed. Suggestions and chat can also be turned off entirely in the settings when choosing the game, to make it more important who your ally is. In serious tournaments it will always be off. Friends can play together against opposing teams. When playing randomly you will automatically get teamed with someone at your rating. If one player resigns but his ally wishes to play on, a new player will take his place. The new player's rating isn't affected if he loses, but goes up if he wins. The options are limitless in what could transpire on such a board. My knight takes a pawn and then my ally eliminates its defender [the fourth color] with his bishop. Or if you're in check, you move your bishop (and snatch a piece) freeing your allies rook to now shoot 15 squares to block it. Or maybe your ally has only a king. You haven't, and you're protecting it, hoping he makes the right move each time he's checked. If your allies' pieces are all eliminated, you may lose even if up substantial material, since they get two turns and you only one. For instance if you fork a king and knight, the forked knight simply checks you, and his ally then slides his rook to block your check even undefended. You must move your king or take the knight, and your queen is lost. Stalemate is only if the color with the only remaining king on the team cannot move. If you lose your king and are losing and your ally has only a king or blocked pawns, he runs for a corner and you surround him with your pieces to stalemate him. The enemy meanwhile tries everything to stop it. Before each move you must take into consideration the move order of the enemy.

Super-GM's like Hikaru, Erigaisi, Niemann, and Keymer, could play against others. Once developing strategy and coordination with someone, you'll be far better with them than even with a higher rated player. You'll have to choose a buddy, and hone your skills with them. What if MAGNUS and HIKARU team up against NIEMANN and HANSEN!? Streaming online, Hikaru (chortling away) sacs Magnus's queen. ('Should I give Magnus's queen?' he asks, his hand on his rook, who'm he promptly sacs for Hans' knight, forcing Carlsen to sac his queen to save it and thus gaining a slight advantage.) In revenge, Magnus needlessly exposes Hikaru's king to Eric's bishop, upon which Hikaru bursts out laughing. A Hansen-Niemann vs Naka-Magnus game will easily be one if the greatest shows chess has ever seen.

ADDING THIS FORMAT COULD LITERALLY DOUBLE THE USERS ON CHESS.COM IN JUST A COUPLE OF MONTHS!

Its popularity would skyrocket, so many people joining just for the co-op. The excitement of such a game cannot be overstated.

There is so much room to improve chess. The greatest minds on the planet should be putting their heads to improve, expand, and promote the game just as they do to play it. Hikaru and Naroditsky should be asked on this variant. The rules don't have to be exactly as I layed out. They can change them slightly if it makes the gameplay and co-op better. (Perhaps pawns should be allowed to promote to kings in this format.)

Millions of new puzzles can be made. There's also no worries about cheating or theory in this format.

Even just adding a co-op mode to regular chess is a great way to expand the game. The best way to add co-op to regular chess is to make that two people must agree in order for any move to be played. Any move you attempt is shown as a suggestion to your partner. If they second it, it goes. In low time, or if chosen, any of you can move, simply whoever goes first. A 2nd option is that every second move is traded off between the two, and a 3rd is that one picks the piece, the other moves it.

IF YOU LIKE THE SUGGESTION, VOICE YOUR SUPPORT HERE AND NOW. IF NOT THE DEVS WON'T DELIVER. USE YOUR INFLUENCE TO MAKE IT HAPPEN.

Yours truly.

I dont know why nobody has said anything here, but I believe this is a very cool idea.

Thanks.

Its fine. Can't believe more people aren't here tho.

I'll be here to make the crowd of supporters seem bigger that way more supporters join lol.

MagnusCarlesn oh mah gahh

If I post a comment here once every couple hours it'll keep the thread at the top of the list, thus gaining more posts and support for the idea to be instated. These forums work like dominoes, if you can just get the momentum going, it'll roll on, on it's own.

Okay. Lets start. 1.p4

It's white first, then green, [then black & brown,] so it would be say: 1. e4 p4, g6 j6

After e4 and j6 White's queen is targeted by brown's bishop. He can defend it either by his g pawn, f pawn, knight or bishop. If white defends with his bishop, then brown must either trade, or defend his, or he'll lose it, because if he can't recapture with his queen or He'll lose his king. His ally though can also defend it on his coming turn by moving his pawn to h5. 2. Be2 o3, h5 Nn6

There are thousands of new tactics and strategies.

A discover-check where an ally can reveal the attack of his partner is counted as a check with all its rules, but only if it's in one move; if it's green or brown checking, and white or black revealing it.

As for stalemate, I wrote that even if only the player on the team with the second king can't move, it's already stalemate. However, this rule must be tested. If it's too easy for the losing team to force draws by stalemating their ally, then the rule will be changed; that stalemate is only if both players on a team cannot move a turn.

Anyone that's read this post, please spread word of the idea best as you can!

Magnus Carlsen has all but said traditional chess is stale and he prefers 960. Honestly, compared to this co-op I'm proposing, they're both boring. Magnus himself would 100% be thrilled with the idea of allying with another GM on this board against 2 rivals. The format can be played with all the 960 versions as well, if it's theory is ever mastered at top lvl. Yet even so, the possibilities in this version is a 1,000-fold that of traditional chess, and there’s no need for it.

I HATE THINKING IN NEW DIMENSIONS AND GOING INTO WILD CHESS THAT HAS NO THEORY!

Then be glad I didn't make it 6 players with QRSTUVWX columns as well. The plan is for this to be the norm one day.

I been playing around with some ideas involving a 10 by 10 or 12 by 12 board with a few new pieces, with comparable but slightly different than standard moves (no OP super pieces). This looks really cool though too! So many different strategies to consider! Teammates work together to control the center? Or separately to control the center of their wing? Just that question alone really makes me ponder.

The main point of this variant is is to experience truly exciting teamwork with a friend in what’s very similar to regular chess, while maintaining full control over your complete arsenal. Here I've seamlessly integrated it into the game. In all major sports there's the sense of comraderie amongst teammates, adding a critical thrill to the games. There's no feeling quite like when teamwork is flowing smoothly; and even the best quarterback is worthless if his buddies don't show up. Chess lacks this integral component and I wish to change that.

In tournaments, each team gets to choose which of their players will be white [black], and which green [brown].

I believe the stronger player should always go first, since he can reveal tactics and strategies for his ally, though it's got to be tested to say for certain.

Also white short-castles to the center, & green long-castles, so there's an inherent difference to which color you are. But players are nearly completely dependent on their ally, so I doubt there's such a thing as being better at one color than the other.

As for for each teammate trying to control the center of his wing, or making a joint effort for the boards' center, that's probably only up to Stockfish to decide. I feel like after 10 moves in, even top engines will be baffled by all the possibilities.

I also think the Rooks' value will go up, and the knights' slightly down, in this format.

I love the idea, we need more variants in chess and I think you have found it
