I am a blind chess player on Lichess. I came across a position in which I wanted to promote to a rook. I learned that you can promote by writing like this:
a8=n // promote the pawn at a8 to a knight.
Thus, I modified it to this:
b8 = r // promote the pawn at b8 to a roke.
The error it gives me is: "Envilate move."
I'm not sure what I did wrong. How is it done? Here is the link to the game: https://lichess.org/QlZNv9I8 It might look stubid because I wasn't playing the game.
I figured out what is wrong. To promote a pawn to another piece, I need to first type the letter in which the pawn is, followed by the position I want the pawn to go, and lastly the equal sign with the piece I want to promote to.
Here is an example:
"Promote a pawn to a knight"
ee8=n "promote a pawn to a knight"
Here is how it works.
My pawn is at the letter e and I want the pawn to go to e8. So I typed:
ee8
The pawn should be a knight that is where =n came from.
Again here is the algebraic equation to use:
ee8=n
