White's pawns can move backwards but black's can't.

What are things black likes to do that they wouldn't do anymore? How does white abuse this?

this thread is completely un-understandable.

Suppose the rules of chess were changed where white's pawns could move backwards one square. What does this change?

Also suppose, separately and exclusively, a different change where white's pawns could also capture backwards normally, what does this change?

It's an unfair change that buffs white, black receives no change.

What irritates me the most is that white's pawn can time travel but not black's. It' so unfair.

@migutier What do you mean time travel? Do you mean like go backwards and calling what I suggested time travel or that in lichess white uses less time for pawn moves? Sorry to ask, that probably isn't what you meant but I want to make sure?

@IPunishDaddy2007 my answer was a joke, I thought your post was one also. If it's not the case I apologize, the truth is I did not understand it.

Oh, I am trying to brain storm what would happen if one side's pawns could move backwards and the other side had to play by our current rules

@IPunishDaddy2007
Why the hell would one do this? The game would be so unbalanced that no one would play it. Thinking about it would be pointless.

@Official_LLL That's like asking why someone might want to solve puzzles from an illegal position or explore openings / lines nobody would ever play or even explore odds games or the like.

Or why a LoL player might want to look at certain matchups in isolation or why a chess grandmaster might want to study an individual piece, or even why someone might play training games hyper focusing on some complex or idea.

Think about it, i'm sure you'll be able to figure it out.

It would have a massive impact on the game and give white an overwhelming advantage. Pawn structure strategy is fundamentally based on mitigating the fact that pawn moves inherently 'weaken' structure because they can't move backwards. It would also allow white to open up closed positions without the need for breaks or giving up pieces. etc. I have no idea about the extent of the advantage but I would say at least rook odds, probably more.
