Understanding the Sicilian Scheveningen (Keres Attack)

1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 e6
6 g4 Line

What's the game plan for White?

White intends to gain space on the kingside
( 6 g4, 7 h4, h5) and pressurize Black's game
in that sector (8 Rh1-g1, 9 gxh5 10 Bg5).
In the center, he aims to take advantage
of the half open d-file ( 11 Qd1-d2, 13 0-0-0)
and execute an appropriate f2-f4 advance.
However, the isolated h-pawn could be a
potential weakness in his set-up.

What's the game plan for Black?

Black wants to contain White on the kingside
( 6 ... h6, 8 ... h5) and retaliate on the
opposite wing, beginning with 12 ... a6,
followed by 13 ... Bd7 and 15 ... b5.
To give the attack more punch, he intends
to play ... Nc6-e5-c4. As always, a timely
... e5 or ... d5 is crucial to his survival
in the center. With regards to king safety,
... 0-0-0 is an option, although it's not
uncommon for the monarch to remain
seated on e8.

Not really, no. White's pawn moves on the kingside aren't there to
gain space but to spearhead an attack and discourage Black from
castling.

One of the key features of the Sicilian is that Black, by playing
1... c5 more or less commits himself to castling short or not at all.
Castling queenside is possible but fairly rare in the open Sicilian,
since it puts the king on the semi-open c-file.

This leaves two basic game plans. If White castles short, a pawn-lead
attack on the kingside weakens his own position and Black can hope to
counterattack if he can survive the initial assault. Alternatively,
if White castles long, he can lead with his pawns on the kingside
but exposes himself to the potential for a black pawn storm on the
queenside. The side that switches to defence too early or too late
typically loses.

The point of the Keres attack is that White gets his pawn storm in
first and will castle long when he has time. Black has three castling
options. Castling short looks suicidal, since the pawn-storm race is
sure to be lost. Castling long is awkward, as it leaves the king on
the semi-open file and denies Black his traditional queenside counter-
attack. Not castling at all leaves Black's king vulnerable in the
centre. So, all of Black's castling options leave him with difficult
problems to solve.

Do the stronger players think I'm missing anything here?

Hence "... and pressurize Black's game in that sector (8 Rh1-g1, 9 gxh
10 Bg5).
