Suggestion - New Variant - Gravity Chess

I'd recommend play-testing some games in the forums. I think you'd find white tends to win.
Once white moves a pawn, the pawns drop down, giving white a half-open file. At that point, any black pawn move immediately gives white a free rook. Black therefore has to move a knight instead - but that makes the rook drop down, leaving the pawn unprotected. White therefore gets at least a free pawn guaranteed on his second move.
Not only that, but there's now a white rook in perfect position to eat his way down through the black position.

Yes
How about this - At the start of the game it is normal chess ( but from a side view ) . After the first kill , gravity becomes active and after every kill , gravity and anti gravity became active alternatively . If there are no kills for 3 moves continuously , it comes back to normal chess . And , you can capture pieces using gravity / anti gravity in your first two rows .
I already posted this in Beta but I want to see what you guys think about it
