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?
