Vienna Game (compare p. 35).

It is contrary to the principles governing sound play to bring out the Queen early in the game. The opponent frequently has an opportunity of gaining a move by driving off the Queen, developing a minor piece at the same time. In the present case Black might have gained the advantage in the following way: 5. … Q Kt-B3. Now if: 6 KtxKt then Kt-Q5!; 7 Q-Q3?, PxKt; 8 QxP?, B-KB4. If, however, 6 B-Kt5, Black obtains the better game by playing 6. … KtxKt; 7 KtPxKt, Q-R5ch; 8 P-Kt3, Q-K5ch; 9 QxQ, PxQ; 10 BxKtch, PxB, with two Bishops on open diagonals. There is no harm in the doubled pawn, as White cannot attack it. Black’s immediate threat is B-R3 or KB4, which exerts pressure at Q6, and White will find it difficult to advance his QP.
5. … P-KB4
This move is open to discussion, as the Kt which it means to support can be driven away by P-Q3. On the other hand, if White does play his QP to Q3, Black can prevent its further advance by P-Q5, after which the White KP is insecure and the KB somewhat shut in.
6. P-Q3 KtxKt 7. PxKt P-Q5 8. Q-B2!
White offers his QBP in order to be able to strengthen his centre by P-Q4, and to free his pieces. To protect his QBP would be inferior, e.g. 8 Kt-K2, Kt-B3 or 8 B-Kt2?, PxP; 9 BxP, B-Kt5!; 10 BxB, QxR5ch; 11 Q-B2, QxBch; 12 Q-Q2, Q-Q5.
8. … PxP?
It would have been better, of course, to continue developing with Kt-B3, which at the same time maintains the pressure on Q5.
9. P-Q4 B-K3
