{Nigel has a 3:2 lead, so it is quite simple for Zahar. He has to win the last
game, a draw is of no use. This "must win situation" is unpleasant, but every
chessplayer has already been in there.} 1. e4 e5 2. Nf3 Nc6 3. d4 {Zahar was
not too successful with the Ruy, so he goes for a new opening. But the real
surprise is his next move.} exd4 4. Bc4 {# The last time I saw this position
was probably when I played a junior tournament.} Nf6 5. e5 Ng4 {For the second
time in the match I try to find very old books to give you a little more
information. And I found a very nice book written by Keres in 1973. Those were
the days, the book has 350 pages and I could learn six or seven different
openings when I was 12 years old. Nigel's 5.Ng4 got half a page, and Keres
knew already in 1973 that "this knight move is better than it's reputation".}

# White gets this Na3 for free, because Black has to play a6 to stop Nb5.} a6

do not mind putting their knights on the rim. It is important to have f7 well
protected.} 10. Re1+ Be7 11. Bg5 Nf5 {#} 12. Bb3 $5 {Here Zahar spent oceans

Karlsbad 1907 International Chess Tournament, pp. 372-373. All comments are
Tartakower's unless otherwise noted.  The feature of the following beautiful
game is the thorough manner in which White takes advantage of the e-file,
which he opens at the cost of the temporary sacrifice of a pawn (8. 0-0), and
finally controls at the cost of another pawn (19. d6). His forces penetrate
into the hostile position (18. Re7, 25. Nfe7, and 29.Ne7), with the most

Tartakower's unless otherwise noted. The most admirable feature in this
important game is the manner in which White keeps the whole board under
control: consolidation on the right wing (15Bh6), break through on the left 
(23.a4), and decisive sacrifice in the centre (28.Rxd8). Marshall: It was in
this game, one of my most memorable tournament encounters, that I demonstrated
the soundness of this famous old attack, Although the merit of my innovation
