LeSwamp: A) 7.Ne2?! Other moves, such as 7.0-0 ; 7.Ne4 or 7.Bf4 could be better to secure an advantage.
B) 9.h3!? This move looks like a loss of time. Worthy of consideration are : 9.Qc2 ; 9.Bf4 ; 9.0-0 .
C) 9...Ne8?! Not too good. 9...Bd6= ; 9...Re8 /= or even 9...a6 seem better.
D) 10...g6? 11.Bh6! Puts Black in trouble. There were only two sound moves : 10...Nf6 and 10...h6 . Now, after only 10 moves, Corzo almost got a winning game!
E) 12...f5?! 13.0-0-0! Worsens things! 12...Re8 13.Bxg7! Kxg7 14.h5! Rh8 huge advantage White ; or 12...Bf6 huge advantage White.
F) 13...Rf7?! There were 13...a6 with idea of b7-b5 ; 13...Bf6 14.Nf4 (14.Kb1 Kh8 ) Rb8 with idea b7-b5 ; 13...Re8 .
G) 14.Ne5? Nxe5 (only move) Corzo missed 14.Nf4! Bd6 15.Kb1 with a winning game.
H) 20...b5?! Giving a pawn to open the b-file to try attacking the White king is understandable. But in the present situation, it simply loses time and material for nothing valuable. 20...Bd7! 21.h5 (21.Bg5 Raf8 clear advantage White) Nxh5 (21...g5? 22.Nd5! Bd8 23.Bxg7 Kxg7 24.h6+ Kf8 25.Nb4! Qb6 26.Rxd7!! Rxd7 27.Qe5! Rf7 28.Qh8+! Ke7 29.Re1 ) 22.Nxh5! gxh5 clear advantage White.
I) 21...Qb6!?/?! 22.Bc4! Better is 21...Qc5! 22.Bg5! (22.Bc4 Rb8 (only move) clear advantage White) Qe7 huge advantage White.
J) 22...Bxc3?! Better were 22...Rb8 23.b3! (23.Rd3 a5 huge advantage White) c5 ; or 22...Rf8 .
K) 30...Kh6?? Hara Kiri! Capablanca had to play 30...Kg8! huge advantage White, but with still some tiny hope.
L) 32...Qf3?! 33.g5+! 32...Qd4 33.g5+! Kh5 34.Qxh7+! Kg4 35.Qxg6! Rb8 .
M) 36.Qxg6. Stronger was 36.h5! gxh5 37.Rc1! with a very easy win. (37.g6?! Rd8 38.Rc1 (only move) (38.g7?? Rd1+! 39.Kc2 Qe2+ 40.Kb3 Rd3+ 41.Qxd3+ Qxd3+ etc.)).
N) 36...Rd8?! 37.Qc2! Better is 36...Rc8.
O) 37...Re8?! 38.g6! 37...Qd3 38.Qxd3+! Rxd3 39.g6! Rd8 40.g7 Kxh4 41.g8Q Rxg8 42.Rxg8 would put a longer resistance! Resigning was also a possibility!
P) 40...Kg4?! 41.Qg5#. 40...Rh2 41.Qc8+! Kg2 42.Rc1! with idea of g6-g7 ; or 40...Kg3 41.Qg5+! Kf2 42.Qc5+! Ke2 43.Qe5+ Kd2 44.Re1! etc.
