Alexander Alekhine Sergei Freiman Cologne 1911 White to move
White’s position is better, but at the moment, the black pieces are harmoniously placed, and are able to hold the defensive lines. The next move is designed to provoke disharmony in Black’s position.
A bad reaction, as now White gets the f5-square, which is too great a concession.
He loses after 23...Rd7? 24.f4+–.
The most tenacious was 23...f6 24.Qc3 Qe6 25.f4 Nf7 26.f5 Qe5 27.Qd3 g5 28.Bg3 Qe7 29.Nc4 Bf8 30.Qe2, although here too, Black’s position looks lost, because of the great number of weaknesses.

Alexander Alekhine Emanuel Lasker New York 1924 (3) Black to move
The d4-pawn is isolated and needs defending. Black exploits this:
The weakening of a whole group of dark squares, which this move forces, is very significant, especially in view of White’s lack of a dark-squared bishop.
An attempt to cover the square f4 against an entry by the black queen. But the knight is badly placed here, because it does not perform any other functions. White’s problems are growing.
Including yet another piece in the attack on the dark squares, decides the game.
