{This game was played in the final round, in our match against Armenia. In
order to secure the title of European Champions, it was essential for our team
to win this match, regardless of the score. After a tense struggle over many
hours, the match ended in three draws, plus this far from error-free, but,
from the sporting point of view, extremely important game for Russia.} 1. e4 e5

this variation, and she quickly played a natural, but probably not the best,
move.} ({More interesting is} 13... Qc7 14. Nbd2 Qxc6 {with a complicated

comfortable deployment of the white pieces on the queenside.}) 14. Nbd2 d5 $2 {
In this position, this typical method of opening the game only plays into
White's hands; the e5-pawn is significantly weakened, and my pieces obtain
some excellent posts in the centre.} ({Even so, after quieter continuations,

{Players seem to start looking for other deviations from the Marshall Attack
than just the Anti-Marshall systems.} d6 9. c3 {This variation, which is
usually reached via the 7...d6 8.c3 0-0 9.d4 move order has become quite
popular lately.} Bg4 10. d5 {Although this move might look like a premature
release of the tension in the centre and seems less consistent than 10.Be3, it
can lead to interesting fight where an unaware opponent could easily go wrong.}

relatively successful with the more straightforward} 12... Bxf3 13. Qxf3 cxd5
14. exd5 {. However, towards the end of the century it became clear that by a
well timed a4 White could put the queen side under serious pressure. Therefore,
Black started being more circumspect about giving up the ligh-squared bishop,
a potential reliable defender of the b5-pawn.}) 13. dxc6 Qc7 {Since the pawn
structure is relatively immobile, the best routes for the pieces can be easily
established. The knight has nothing to do back on c6. It would not only fail
to control the relatively weak d5-square but would also be restricted in his
actions by the c3-pawn and his own e5-pawn. Therefore, the queen is better
suited for winning the pawn back, while the knight can dream of being recycled
via c4-b6.} 14. Nbd2 Qxc6 15. Nf1 Nc4 {Black has an active position and needs
just one tempo to complete his development. However, his queen's knight has
not reached complete stability yet which is likely to cause further losses of
time.} 16. a4 {In the Ruy Lopez, this move can be quite unpleasant even if it
doesn't always lead to the occupation of the a-file. The weakness of the
b5-pawn (after the predictable exchange axb5, axb5) could easily become more
annoying than might seem at first sight.} Re8 {A generally useful move,
clearing the f8-square for the bishop in order to prepare the thematic break ..
.d5.} 17. Ng3 {Black finds himself at crossroads now: where should he (re-)
develop his light squared bishop?} Be6 {From aesthetic point of view, this
move looks the most natural. The bishop doesn't interfere with the queen,
which is also placed on a light square and puts the enemy queen side (the
b3-square in first line) under pressure. However, the move has a major
drawback: the bishop can eventually be chased away with Ng5. This will most
likely provoke a further ...h6, which slightly weakens the king's position,
offering White additional ideas for an attack.} ({It is hard to give a
definitive evaluation to the pros and cons, so let's also investigate the main
alternative, consisting of} 17... Bb7 {. This move might look more active,
since it puts the enemy king under some potential threat. However, if White
will manage to maintain sufficient obstacles in the way of the otherwise
terrible battery formed by the queen and bishop, the slightly one-sided
character of Black's strategy would become noticeable.} 18. Bd3 Bf8 19. Qe2 {
Given the placement of the black pieces, the b5-pawn is not easy to defend,
which makes White's last 2 moves easy to understand.} d5 {In order to maintain
the balance even, Black must react in the centre, increasing the scope of his
pieces along the a8-h1 diagonal and clearing the d6-square for the knight in
order to defend the b5-pawn after a further b3. However, this is a double
edged decision since now the b1-h7 diagonal will be open and the e4-square
will be cleared for White's pieces.} 20. axb5 axb5 21. Rxa8 Bxa8 22. exd5 Nxd5

the critical test for the whole line starting with 17...Bb7. The black queen

speaking, Black has a wonderful position. He has just completed his
development in a very harmonious way, while the enemy forces are not that well
coordinated. Strategically, he can also be satisfied, because in the long run
the weakness of the light squares in the white camp (c4 and e4 in first line)
might tell. However, things are not that one-sided. First of all, Black's
minor pieces do not have active possibilities yet and display only defensive
functions (such as controlling the e5-square). Besides, White's kingside
majority is quite threatening. In conclusion, the position remains enormously
complicated and probably equal, although subjectively speaking I would prefer

probably hoping for a slow but consistent attack, based on g5, Qxh5 and g6.

correct, he might have relied on the fact that the enemy minor pieces are
restriced by his central pawns, forgetting for a minute that he has not
completed his development yet, a detail that makes such moves away from the
centre very risky.} (26. Ng5 Bxg5 27. Qxg5 $13) (26. Ne5 Bxe5 27. fxe5 $13 {
