White moonbus, Black lazza, initial ratings within ten points. Notes by moonbus.

This is so far a book line of the Petrov. Equality.

White plans to exchange on e6, leaving Black with an isolani. However, the plan proves to be fatally flawed.

Black's energetic response shows the flaw immediately: Black now has a higher-value target than the isolated e6 pawn, namely White's f2 pawn.

White's lack of development, and Black's superior mobility, make the game completely one-sided. White can no longer hold the f2 pawn or prevent the invasion of his position by the Black pieces.

This is a splendid diagonal for the bishop, as it strikes f2 and g1.

The alternative, ... QxQd8+, RxRd8; Bg5, Rd5 did not look any more promising. White cannot move the queen anywhere else, otherwise there are back-rank mate threats.

White's position is so shattered that it can hardly be improved. Nonetheless, White tries to block Black's powerful bishop.

Opening an escape square, in anticipation of an imminent double-rook assault.

White can no longer avoid the exchange of rooks on the back rank and subsequent loss of the a2 pawn. Further resistance is futile. White resigned. 0-1
