The analysts for the World Team in the Kasparov vs. The World are all rising young chess superstars. These are the next generation of names that will rise to the top of the chess-playing world. If you're unsure what move to play against World Chess Champion Garry Kasparov, our analysts can point you in the right direction with their thoughtful responses.

Fifty glorious moves against Garry Kasparov; well done World. That's the equivalent of going ten rounds with Tyson - and you are still standing.

Over two weeks ago, the race began to get a new queen. With the help of their kings, both sides forced their pawns down the board to the eighth rank. The result: a dead heat. Garry has just 'promoted' a pawn (to use the chess jargon) and The World can do the same on this turn. Actually, it is in the rules of the game that you can promote a pawn to any piece you like: a knight, bishop, rook or queen. But in practice it is very rare that a player 'under-promotes' as the queen is by far the most powerful piece, combining the powers of rook and bishop.

So, The World will get a new queen, and then what? We have arrived at a queen and pawn ending where, in spite of The World having an extra pawn, Garry still has the advantage. Why?

The aims in this ending are the same as in others: to get a pawn to the eighth rank to get another queen. White's single pawn is already far advanced up the board, and supported by the king, to boot. Black's pawns, a long way from the queening square, isolated, and without proper support, do not represent a threat in the same way. Therefore, The World is on the back foot.

How is The World to defend? There are two main ideas.

(1) CHECKING

The main weapon will be to subject Garry Kasparov's king to a barrage of checks. If the king is unable to escape the checks, then the game will end in a draw by 'perpetual check'.

(2) ADVANCE THE PAWNS

While Garry battles to advance his single pawn, The World should attempt to advance its pawns - for two reasons. Although Black's pawns are behind in the race, it does no harm to keep the pressure on; but, as well as that, those pawns can actually be a hindrance to Black, providing cover for White's king to shelter from the checks. Advancing them as far as possible removes that cover and makes it more likely that a 'perpetual check' will occur.

That is a very crude outline of the strategy involved in this ending. Play is going to be extremely complex and subtle. For instance, moving the king one square in the wrong direction could make the difference between a draw and a loss for The World. It is a bit like stepping through a minefield. However, I believe that with accurate play The World can hold the draw. Go to it!

d1=Q to Kasparov's h8=Q

I would play 50...d1=Q. There are no other possibilities in this position. Now we are in an interesting queen game with better chances for White.

d1=Q to Kasparov's h8=Q

The World Team has only one move to make: d2-d1=Q. Finally, after those virtually forced moves, the game arrived at this Queens' endgame. The World Team should hold with no difficulty, since almost all of the lines analyzed show an equal game with the World Champion.

d1=Q to Kasparov's h8=Q

There is only one possible to consider, which is d2-d1=Q.

d1=Q to Kasparov's h8=Q

I recommend The World plays the move 50...d1=Q (Pawn on d2 to d1 with promotion to a Queen).

Our move is obligatory - we must make a Queen. Therefore 50...d1=Q.
