[Alekhine calls the text move a "mistake" and thinks that White had a strong play with 19.a4 and 20.a5 when "White strengthens the pressure on the queen's side without risk, and it is difficult to see how Black can proceed." But Alekhine failed to consider 19...a5! and, despite the ensuing complications, Black is all right after 20.bxa5 (or 20.c5 Nbd5 21.bxa5 Bxc5 22.Rc4 Qd6 23.Rec1 b6= ) 20...Nbd7 21.Rb1 Nc5 22.Qb6 Qc8 23.Qb5 Nd3 24.Re2 Rd7= ]

[Alekhine correctly identifies this as the turning point, but he does not suggest the best continuation. After 28.Be3? Nxe3 29.fxe3 Alekhine the analyst misses what Alekhine the player surely would not have overlooked -- the strong 29...Rd2! (Alekhine continues with 29...Rd3? 30.Qxd3 and White's game is, as Alekhine correctly says, "defensible.") 30.Rc7 Qb5 and the queen will make White miserable.; Instead of Alekhine's 28.Be3?, White should play 28.Rc5! Nf4 29.Bxf4 Qxf4 30.Rc8 and White has equal chances.]

28...Nf4 29.Qf3??
[Alekhine correctly spots this fatal error by White. He even gives what looks to be White's best play here: 29.Qe3 although after 29...e5 Black definitely has the advantage.]
