Game No. 123 in the book (round 14): a Scotch Opening won by Emanuel Lasker (Black) against Jacques Mieses, annotated by Lasker.
5…Bb6By this move Black turns the opening into a sort of Giuoco Piano.
7.Nd5Losing time, in order to exchange the disagreeable Bishops. Black obtains now an even game.
9.Nxc6This exchange strengthens Black's centre; it was unnecessary and deserves censure. From here Black takes the initiative.
17…f6White must not be allowed to get a free board for his Bishops by playing P - K 5.
26.Bxb3The exchange is forced, for if B - Kt 1, Black would stalemate the Bishop by P - Q B 4 and Q B 5, followed eventually by the entry of the Knight at Q 6 via Q B 4 or K 4.
28.Rd1White should have rather played P - Q B 4, in order to get rid of the disagreeable weakness at Q B 4 and Q Kt 3. The Pawn at Q B 4 would be exposed, it is true, but this would be the lesser evil.
31…Nc5Just in time to prevent the counter-stroke P - Q R 4.
36.Qc2After the exchange of Queens, the Q Kt P could not have been defended in the long run.
37…Re6Black intends to play the King via K B 2, K 2, Q 2, Q B 1, Kt 2 to Q R 5, and then decides the game either there or on the King's side. Meanwhile White can undertake little or nothing.
38…h5Necessary, lest after K - B 2, P - K 5 should attack the K R P.
40.g4White sees that Black's King is trying to get away into safety, before the pounding by the advancing Pawns and the Rooks commences; in trying to prevent it by an immediate onslaught, he compromises his own position.
41…d5Decisive.
43.Bxe1If 43) R x R, Kt - Q 7; 44) Q - Q 1, R x R ch; 45) B x R, (Q x R?, Kt x P ch) Q - B 8 ch and wins.
