19.  PxP

P-K4 was comparatively the best move, although Black’s attack would have become overwhelming after P-B4, e.g. 20.  P-B3, B-B5, etc.

19. ...          BxPch!!
20.  KxB         Q-R5ch
21.  K-Kt1       BxP!

Emanuel Lasker won a celebrated game from Bauer (Amsterdam, 1889) with a similar sacrifice of two Bishops, and very likely this is the reason why Tarrasch’s beautiful game only earned him the second brilliancy prize at Petrograd (1914).

          22.  P-B3

If KxB, then Q-Kt5ch; 23.  K-R1, R-Q4; 24.  QxP, R-R4ch; 25.  QxR, QxQch; 26.  K-Kt2, Q-Kt4ch and QxKt.

          22. ...  KR-K1

Not Q-Kt6, because of Kt-K4.

23.  Kt-K4 Q-R8ch 24.  K-B2 BxR 25.  P-Q5 P-B4 26.  Q-B3 Q-Kt7ch 27.  K-K3 RxKtch! 28.  PxR P-B5ch

With Q-Kt6ch Black mates two moves earlier.

29.  KxP R-B1ch
30.  K-K5 Q-R7ch
31.  K-K6 R-K1ch

        Resigns.

If K-Q7, B-Kt4 mate, if K-B6, Q-R5 mate.
