In this structure, White's plan is to advance the pawn to c4. Depending on the situation, he may exchange on d5 and, after some exchanges, saddle Black with an isolated d-pawn. Alternatively, he can continue to push the pawn to c5 followed by a general pawn advance on the queenside as occurs in the game.

14.a4
QUESTION: Where is White planning to castle after this move? Surely the kingside is out of the question with all those advanced kingside pawns? ANSWER: White definitely wants to castle on the queenside as long as he is safe there. At the moment he does not have enough going on the kingside and a premature queenside castling might be detrimental to his king's health. Thus 14 a4 secures the knight on b5 and is actually a waiting move as well. White may want to forgo castling and put his king on d2 or f2 instead. Note especially that Black has no great move for the moment and he cannot eject the b5-knight.

Jobava does not need any further invitation to start opening the kingside with some sacrifices.
