Very nice game. Good effort! A few suggestions to make it better.

The instruction to give x and y is a little confusing i tried entering 3, 6 then 3 and 6 ... it took me a while to figure out that I needed to enter one and then the other. making this small change could make it easier:

try:
 print('give x and y')
 x = int(input("x:"))
 y = int(input("y:"))

Not really a "code problem" per se, but rather a chess problem. The numbering on the board should start from the bottom left corner and move out. And it should count from 1, not from 0. Chess Board

r n b q k b n r 0 
p p p p p p p p 1 
P . . . . . . . 2 
. . . . . . . . 3 
. . . . . . . . 4 
. . . . . . . . 5 
. P P P P P P P 6 
R N B Q K B N R 7 
0 1 2 3 4 5 6 7 8 

So that the white Rook on the King side is at coordinates (1,1) and the other white rook at coordinates (1,8)

The system accepts negative values for x and y, as well as the number 8... all of these generate an error (since the grid currently starts counting at 0)

At the start of the game, the left-most white pawn is sitting all the way across the board

 r n b q k b n r 0 
 p p p p p p p p 1 
>P . . . . . . . 2 
 . . . . . . . . 3 
 . . . . . . . . 4 
 . . . . . . . . 5 
 . P P P P P P P 6 
 R N B Q K B N R 7 
 0 1 2 3 4 5 6 7 8 

You could use unicode chess pieces, this would allow you to free the alphabet and use the traditional Letter-Number chess coordinates. This is the Wikipedia link. You can get them into python using chr()

for i in range(12):
 chr(9812+i)

output:

'♔'
'♕'
'♖'
'♗'
'♘'
'♙'
'♚'
'♛'
'♜'
'♝'
'♞'
'♟'
