Mission accomplished; the knight clearly outshines the bishop.

By the threat ...h5-h4, Black provokes a new weakness.

8.h4 Rg8 9.Rd1 Qg7 10.Qf3 Kh6 11.Kg2 Ra8!

With 12...Ra2+ coming up, Black is clearly better.

Initiating favourable exchanges in order to install an eternal knight on e5.

Preferable was 1...Bxd7 2.Ne5 Nf6! , followed by ...Be8 and ...Nd7 to challenge the white knight, although 3.Qc3 preparing b3-b4 keeps some advantage.

Swapping the last piece capable of challenging White's knight.

From now on White is better on the whole board, thanks to his powerful knight.

Initiating favourable exchanges in order to install an eternal knight on e4.

After 6...Nxc3?! 7.Qb3 Nb5 8.Bb2 0-0-0 9.f5 White gets some initiative – Botvinnik.
