Cotati Chess

I propose a variant rule called Cotati style chess, named after the town in California where I came up with the idea.  It is super simple.  It changes only ONE rule.

Setup

Standard.

Pieces

Standard.

Rules

Instead of a "promotion," when a Pawn gets to the other side the player instantly and automatically wins.  

Note normal Chess rules must be followed. Therefore a player could not make a winning Pawn move (called breaching) while in check unless the move actually got them out of check,  Also, if such a move put them in check it would not be allowed.

Notes

It plays very nicely and gets rid of some of the nonsense, like a losing player fishing for a stalemate or an immature player building a harem (getting multiple queens).  Many Chess variants like GOTHIC or MILLENNIUM could be played Cotati style if the players agree.
