45. “Deep Sicilian” Practice


[Event "Koge"] [Site "Koge"] [Date "2014.??.??"] [Round "?"] [White "Baklan"] [Black "Krasenkow"] [Result "1/2-1/2"] [ECO "B45"] [WhiteElo "2656"] [BlackElo "2631"] [Annotator "Wahls"] [PlyCount "45"] [EventDate "1968.04.05"] [EventType "tourn"] [EventRounds "11"] [EventCountry "DEN"] {My original intention was to present this game already last year. But
then I changed my mind and decided that it might be wiser to provide you with
some theoretical knowledge about the "Deep Sicilian" Logic first. With that
foundation, you will now be able to understand the game on a much higher level.
} 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 Nc6 6. g3 {[#] Ranking only
on 7th place in popularity, this move is clearly underrated. It is not worse
than 6.Be2 (rank 4) and definitively better than 6.Be3 (rank 3). Black has
many decent options, now. One would be to enter the g3-Scheveningen by playing
6..d6. I refrained from presenting this line, as the position tends to be a
complicated Deep Sicilian, where Black might find himself being attacked on
the kingside. It is true, against 6.Be2 I do recommend entering the
Scheveningen with 6..d6. The difference is that there I present the line 9..e5,
with which Black establishes a foothold in the center, thus avoiding any
serious attack.} Bb4 7. Bg2 O-O 8. O-O d6 {[#] That's the defining move of my
repertoire variation. I picked it for two reasons. First of all, my analyses
turned out to be very satisfactory, which complies with the important
characteristic of QUALITY. Secondly, there were only 9 games available, which
made this line virgin territory to some degree. There was plenty of scope for
original analyses and hence the characteristic of ORIGINALITY was complied with,
as well. If you remember my blog post 44, this combination is what makes for a
QUALITY SIDELINE. The structure is special in so far, as we see a hybrid
between a Deep Sicilian (pawns on e6 and d6) and a Sicilian with active piece
play, since the bishop has moved beyond the central pawn shield. Which of the
two elements is the dominating one, depends very much on White's decisions. As
it turns out, after 9.Nde2 Black will have the best of both worlds - the sound
Deep Sicilian structure and active piece play linked to the special location
of the bishop.} 9. Nde2 $6 {[#] This move follows a certain logic as it
prevents doubled c-pawns and clears the d-file for potential pressure against
d6. However, the drawbacks way heavier. Pressure is released from c6 and the
queen's knight is left on an awkward place were it will very likely be
attacked by Black's b-pawn. The deeper meaning of this will become evident in
the course of this game.} a6 (9... h6 $2 {happened in 1-0 (38) Souleidis,G

to prevent 10.Bg5.}) 10. h3 {White prepares both pawn thrusts, g4 and f4. The
latter could otherwise run into Ng4-related tactics. Additionally, a bishop on
e3 won't have to fear this knight sortie anymore.} (10. Bg5 $2 h6 11. Bxf6 Qxf6

Nde2. However, as it represents the line 9.Nde2, I decided to use this order
for the sake of simplicity.} 10... Bc5 $1 $15 {[#] As the knight on c3 is
firmly fortified, the bishop turns towards a more interesting diagonal. At
the same time, the square b4 is vacated for the b-pawn. Obviously, Black is
doing fine, but is he really slightly better, as I claim? If you let Stockfish
with his 3500 Elo run for several minutes, it declares equality. In my
opinion, it is positions with such discrepancies, which are truly interesting
and where your chess understanding is put to the ultimate test. Okay, this is
how I make my case: As we know from the great Bent Larsen, by opting for the
Open Sicilian, White is actually playing a gambit, as he sacrifices his
valuable centre pawn for Black's c-pawn. In return he gets space advantage and
initiative. Now the proof is on him, to convert these dynamic assets into
something more tangible. Otherwise, Black's superior structure will possibly
count in the long run. So, how is the state of White's initiative? In order to
show something, White will have to push his kingside pawns, as it happens in
the game. However, if we compare White's attack with other Open Sicilian
positions, we realize that he is actually rather late to the party. After all,
he invested in moves such as 9.h3 and 10.Nde2 and will move his pawn to g4 in
two steps. Such long-winded attacks bear the risk of not being efficient. But
that's not all. In this specific context not being efficient isn't a neutral
outcome but a negative one, as irreversible weaknesses of White's king safety
will occur in the wake of such pawn thrusts.} 11. g4 {The questions is whether
White is doing better by omitting to weaken his kingside and play solidly
instead. While this might be or might not be the case, there still is a
problem. Solid play will not deter Black from conducting his automatic
queenside expansion with the consequence of gaining space, dislodging the Nc3
and creating weaknesses in the camp of White's queenside pawns (minority
attack). Additionally, he still has his pawn majority in the centre. No, there
is no way for White to escape his fate of being the underdog, as I see it. If
you still have blog post 52 in mind, you will recall that this is exactly what
I depicted as WHITE'S DILEMMA IN THE DEEP SICILIAN.} (11. b3 Rb8 12. a4 (12.
