Brand NEW Chess rule, that should be a rule....

the king should be allowed to dribble.

No, I was serious about that. Chess with best play is a draw. It isn't that of an disadvantage to have black anymore. In the current world cup there were many black wins out of equal positions because white risked too much too win.

In the suggested variation OP suggested a draw cannot be achieved because even if all pieces are exchanged there will always be a player who reaches the other side first because in chess we alternate between the players.

well, same thing for a pawn.  If all the pieces are exchanged, somebody always ends up with that lucky pawn that is closer to the finish line.  I still think the "Touch Down!" play is awesome.  Try it a few times, it's highly addictive.  Talking about it isn't the same as playing it.

So you think that with finessed masterful play of the '+Touchdown' variant described, the first_move advantage would be significantly higher than it is in standard chess, perhaps enough to guarantee a victory ?

I think the idea needs some reworking.  As the game is very balanced. I would propose that to offset whites advantage of first move: which is a substantial advantage in beginning game. For example: in top levels if white wants to draw there is very little black can do about it sometimes. So if the Black king can get to the white Kings starting square (E1)  and only the Black king would be allowed this win condition. It would balance out some of whites opening advantage with some of blacks endgame advantage, hence keeping the balance. In addition it would have to be the E1 and only E1 square that the Black king needs to make it to, as it will be easier for white to protect one square instead of a whole rank. I think this balances out Black and White to almost perfect equality. And being black would not be a disadvantage like it currently is in almost all formats. It could be called "Robbing the Whitehouse" or "The Squatter win Condition" or even the "Long King Walk" or just name it after me.

An idea expanded on this "touchdown" idea, could be a new variant called "Football" chess, where the two players take turns trying to get their king to their opponents back rank, while the other player defends. If the defending player "checkmates," the opponents king, it would be a "turnover." The game could end after a given time or a certain amount of attempts by each player, and the winner would be whoever scored the most points. Interesting idea.

Its called racing jings

*kings

you can just block with other king

The dumber the idea, the lower the rating-mic drop.

At least make it a variant

It is Racing Kings, but there the setup is different.
