good enough in itself. After the exchange at c4, White's doubled pawn, even
though isolated, would do no harm, on account of its central position; it
would hamper Black's pieces and could not be easily attacked. But it was a
condition, sine quo non, to secure the Queen Knight against Ba5 by say a3, for
the trebled Pawn on the c-file has no mobility whatever.} Bxc4 9. dxc4 Ba5 10.

game should be lost in consequence. Hence White plays va banque for attack.}

{I played rather poorly at the Junior Invitational. This game came after two
consecutive losses: the first loss resulted from a blunder while up a rook and
the second from 22 moves of opening preparation by my opponent. Elliot was
also having a rough tournament, having lost his last three games. Somehow,
however, in this situation, we managed to create quite an interesting fight.}

This is my favorite opening- The Najdorf variation.} 6. Be3 e6 7. Be2 $5 {
This is a fine move, but it takes the game in a whole new direction, into
Scheveningen territories.} (7. f3 b5 8. Qd2 Nbd7 9. O-O-O (9. g4 h6 10. O-O-O
b4 {All of this is relatively mainline stuff.})) 7... Qc7 {This flexible move
is favored by Garry Kasparov. Black wants to play b5, but at the moment it is
bad; Qc7 is a move black always wants to play, while it is not yet clear
whether he wants his b8 knight on c6 or d7.} (7... b5 $2 8. Bf3 $1 e5 (8... b4

This looks extremely drawish}) 15. g5 Nd7 16. Bg2 {
White has a plan of playing Rf3-h3 and Qh5, although it is a bit slow.} f5 $6 {
Diagram # This is a good idea, but maybe bad timing. The only real plan I
could see for white was Rf3-h3 and attack, and f5 would be more effective if
white's rook was already misplaced. However, black must also always look out
for the possibility of white playing f5 himself, so I decided to end that idea
right away. ***PLEASE INSERT DIAGRAM HERE before 17.Qe2!***} (16... Rae8 17. f5

positions because I thought the knight on d5 would be too powerful and white's
extra space on the kingside would give him good attacking chances, but in
reality there is not too much to fear and black is likely to be slightly
better here.}) 17. Qe2 $1 {
A good waiting move from Elliot. White now threatens Qc4.} Rae8 {

white plays Qg4.} 21. Qg4 {Diagram #} Nb6 (21... d4 {This was the computer's
suggestion, after which it says black is better. In the game I thought forcing
white's bishop out of the way to make room for his rook and permanently giving
the white knight a healthy home at e4 was a bad idea, but concrete variations
prove otherwise.} 22. Bxb7 Qxb7 23. Bc1 Qd5 24. Ne4 c4 {
