GM Sandipan Chanda took on Vassily Ivanchuk in the sixth round of the Gibraltar Masters 2018. Let's go over the initial moves:

Black (Ivanchuk) pushed his pawn to a4 in this position.

Black has just played a5-a4 with the obvious intention of not letting white to expand on the queenside.Though this idea is typical, I am not sure if its an asset or liability in this position as the pawn on c5 is clearly a major asset for White. It not only restricts Black's pieces but also has firm control over dark squares as moves like Nc3-b5 to d6 are always in the air.

Sandipan takes the pawn on a4 with the knight. But Rxa4 Bb5+ Bd7 Bxa4 Bxa4 yields two pieces for a rook and a pawn. Isn't it supposed to be a good position for Black?

Look at the engine evaluation! They are shouting out loud that Black is better!

White goes Qb4  and though engine claims that Black is better here, I think the position is double-edged in a practical game as white's queenside pawns would become dangerous.

Qd7-b5 was a clear error by Ivanchuk which was met with the cute move b3!

Much better would have been to 0-0. And the question arises how should White play?

I have analyzed the above position in great depth and come to the conclusion that it is not as black and white as the computer suggests. There are areas in grey and Black must play very carefully in order to keep his advantage. Have a look at my analysis below:
