5…Be7 5....B—B4 leads to a variation in the Giuoco Piano, known as Max Lange's attack. The move in the text is not good.
6…O-O If 6....KtxP; 7 Kt—B5, 7 O—O (or 7....P—KKt3; 8 Q—Q5+, or 7....P—Q4; 8 KtxP ch., 8 K—B sq.; 9 QB—KR6, 9 K—Kt sq.; 10 BxP+); 8 Q—Kt4, 8 P—KKt3 (or 8....Kt—Kt4; 9 KtxB ch.+); 9 Kt—R6 ch.+
7…Ne5 Which only ultimately leaves a further mark for the hostile attack from the dangerous KBP, P—Q3 was much better.
8.Be2 Excellent play which provides against Black's entrance of Kt—Kt5, after P—Q4.
9…Nc6 Of course, if 9....QKt—Kt5; 10 P—K5 wins a piece.
11…Bc5+ An ill-judged move. The square of QB4 ought to have been reserved for the entrance of the Kt in order to weaken the adverse attack by B—Q3. The retreat of the Kt—Q2 at once was therefore, by far superior.
15.Qh5 A very weak move which creates a dangerous hole in Black's King's side. Either Kt—Kt3 or B—Q2 were much better.
18…Nc5 A much better defence was 18....Kt—Kt2; for if 19 P—K6, 19 KtPxP; 20 PxP ch., 20 KxP; 21 QxRP, 21 Q—B3, with a good game.
19.e6 Beautiful play and winning by force.
20.f6 Quite good enough, but the more simple initiation of the final assault by 20 PxKtP would have finished sooner, and also might have led to attractive brilliancies. For, supposing 20 PxKtP, 20 PxP (if 20....R—K2; 21 R—B7, 21 RxR; 22 PxR ch., 22 KxP; 23 Q—R5 ch., and wins. Or if 20....P—KR3; 21 BxP, 21 P—K4; 22 Q—R5, etc.); 21 R—B7, 21 KxR (or 21....B—Kt2; 22 BxP and wins); 22 Q—R7 ch., 22 K—B3 (if 22....B—Kt2; 23 R—B sq. ch., and wins); 23 R—B sq. ch., 23 K—K4; 24 B—B4 ch., 24 K—B3 (or 24....K—Q5; 25 Kt—K2 mate); 25 B—Kt3 dis. ch., and mates next move.
