Here are some chess puzzles taken from the games of the Georgian
champion, Zurab Azmaiparashvili. It's White to move and win except
where noted.

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).

Properly, it's Forsyth-Edwards. As I recall, Edwards added the stuff
on the end describing who has the move, who can castle and so on.

Correct.

Not quite.
K white can castle kingside
Q white can castle queenside
k black can castle kingside
q black can castle queenside
- neither side can castle
(Note that, here, `can castle' means that neither the king nor the
relevant rook has moved. There may be features of the position that
prevent castling right now -- attacked squares and intermediate
pieces, for example. The letters should appear in the order I've
listed them.)
To finish the description above, the `-' would be replaced by the
square to which an en passant capture could be made, if a pawn had
just advanced two squares (even if no en passant capture was actually
possible).
The two numbers at the end are the number of half-moves (ply) since
the last pawn move or capture, and the current move number of the
game.
Dave.

It's Forsyth-Edwards Notation (FEN).
