With rooks on the board, the opposite-coloured bishops are not such a drawing factor, and the realisation of Black’s advantage does not pose any great difficulties.

If Black could succeed in blockading e5, he would have an excellent game. However, it is White’s move, and he carries out a temporary pawn sacrifice, to open up play for his pieces on the light squares:
The black pieces are totally lacking mobility, whilst White’s cooperate excellently and control all the key squares.

In such a structure, the black Be7 would be better on g7. In that case, his king would feel safer, and the breaks e4-e5 and f4-f5 would not be so terrible. White’s pieces are all pointing at the kingside and on the long diagonal, and the Bb2 has no opponent. Whilst Black has no time to organise himself properly, White attacks.
19...Nh5 20.Ne4 Bxe4 21.Bxe4 dxe5 22.fxe5 leads to a large advantage for White – White can cripple the knight on g7 with g2-g4!.
White uses the same idea as in the game after the preliminary exchange 19...dxe5 20.fxe5 Nd7 21.Be4!. After the exchange of bishops, the white knight breaks into the black position with great effect, whilst after 21...Bc8, White carries out a nice attack: 22.Nd5! exd5 23.Bxd5 Bf6 24.e6! fxe6 25.Bxe6+ Kg7 26.Rxd7+!, mating.
