Why not try that other
Marshall Gambit?
By IM Merijn van Delft & IM Robert Ris
Frequency
Between Wijk aan Zee and events like the Topalov-
Kamsky match and Linares, we have time to look at
the level slightly below that. At the Moscow Open
many new interesting ideas were played.
WHAT’S HOT?
Score
In our game of the week White did a good job with the Marshall
Gambit in the Semi-Slav. Since White lost quickly in the high-
profile game Van Wely-Gustafsson in Dortmund last summer,
many questions remained, but in Lysyj-Sjugirov some of them are
answered. In fact, in the diagram position all three ¥ moves have a
nice score for White. Below we take a closer look at 9.¥a5.
Creativity is the key word in describing further opening
developments this week. While some former world champions
have predicted the death of chess and these days opening
novelties are found beyond move 20 or even move 30, it is still
possible to invent new stuff early in the game. Even in very well
known positions, that is!
Nikolenko’s 6.¤d5!? is a very tricky anti-Dragon line that never
caught on after it was played by Tal amongst others back in the
seventies. Entirely new is Boris Savchenko’s 6.¤3e2!? as a way
to battle the solid Caro-Kann, and Hillarp Persson’s 8...b5!? in
the Slav is a spectacular new pawn sacrifice that was repeated in
Moscow by Lastin. Chess is not exhausted yet!
Source: Megabase + TWIC, 2500+ only
At the level slightly below the absolute world top, most openings seem to be playable again. Remarkable is the further suffering of the
Sveshnikov. In all grandmaster games this week, the positional 9.¤d5 ¥e7 10.¥xf6 ¥xf6 and now the trendy move 11.c4 was played,
with good results for White. Is it too much to weaken the d5 square after all? The game
Timofeev-Smirnov features a beautiful positional exchange sacrifice followed by strong
domination (see page 3).

Beating the Semi-Slav: 9.
¥
a5 in the Marshall
Suddenly the Marshall Gambit of the Semi-Slav (4.e4!?) appeared in a super tournament last
year (Van Wely-Gustafsson, Dortmund 2008) but the brave Dutchman lost after a mere 18
moves. At the Moscow Open, GM Lysyj fared better, using a devastating novelty.

1.d4 d5 2.c4 e6 3.¤c3 c6 4.e4!?
The Marshall Gambit is a very principled way to
grab the initiative right from the start. After 4.¤f3
Black may want to play the sharp Noteboom
Variation 4...dxc4 5.a4 ¥b4 6.e3 b5 7.¥d2 a5
8.axb5 ¥xc3 9.¥xc3 cxb5 10.b3 ¥b7 11.bxc4 b4
12.¥b2 ¤f6 with lively play ahead.
4...dxe4 5.¤xe4 ¥b4+ 6.¥d2 £xd4 7.¥xb4
£xe4+ 8.¥e2
Now Black is a pawn up, but his black squares
are weakened and he is lacking in development.
8...¤a6
8...£xg2 has always had a dubious reputation,
ever since the game Ragozin-Botvinnik,
Moscow 1951.

5.¤c3 e6 6.¤h4 ¥e4 7.f3 ¥g6 8.£b3 b5
This odd-looking move was
invented back in 1971 already
and used by both Ljubojevic and
Tal. With the chosen move-order
White is aiming to avoid a sharp
theoretical Dragon. White is
threatening ¤b5 and so provokes
Black to weaken his black squares
with 6...e6. In Nikolenko-Li Chao,
Black's 9...¤e5 is a serious error
and so you can see it's not White
who gets punished for playing twice
with the same piece in the opening!
The Caro-Kann is a tough opening
to beat, although it was under
pressure during the Corus Chess
Tournament. The classical main
line with 4...¥f5 is well analysed,
but new ideas keep cropping up.
Even on move six novelties are
possible as is witnessed by Boris
Savchenko's 6.¤3e2!? against
Vuckovic. The idea is to exchange
the bishop on g6 while ending
up with a more potential ¤ on g1
instead of g3.
This inspired new idea was
introduced during the Corus
Chess Tournament last month
by Hillarp Person. The Swede
probably got inspired by Dobrov,
who played the same move in the
Latvian (7.g4) attack in the Semi-
Slav. Giri's decision not to accept
the pawn sacrifice doesn't seem
to be the critical test of Black's
setup, since c8-bishop is outside
the pawn chain compared to the
Chebanenko-Slav (4...a6).
White is scoring very well with the
relatively new 11.c4 in the positional
main line of the Sveshnikov. In
Timofeev-Smirnov the novelty
17.cxd5, giving up the strong
square on d5, was backed-up by
the fantastic positional exchange
sacrifice 20.¦xc5! after which White
kept domination until the end.
