I'd like to know more about this notation:
For example,
1rbqk2r/p1n2p2/3p3p/2pPn3/2B1N1p1/1P2B1b1/P2Q1PP1/2R1K2R w Kk - 0 1
What does it mean?

It's called Forsyth notation. The lower-case letters are black
pieces, capital letters are white, and numbers stand for empty
squares. It starts with Black's back rank, at the square a8, and
proceeds left to right and top to bottom. To interpret:

1rbqk2r -- a8 empty, black rook on b8, black bishop on c8, black
queen on d8, black king on e8, 2 empty squares, black rook on h8, / =
end of rank
p1n2p2 -- black pawn on a7, empty b7, black knight on c7, two empty
squares, black pawn on f7, two empty squares.

And so on down the diagram. I'm sure you've got the idea now. If I
recall correctly, the "w" near the end means "white to move," and the
"Kk" means both kings are still able to castle (I think).
