If White had played 9. P takes Q P, Black's best reply would have been 9. ... P takes P, attacking the Rook; if 9. P takes Kt P, Black replies 9. ... B takes Kt P, with a promising attack.

THE VIENNA OPENING.

If, after 1. P to K 4, P to K 4, White plays 2. Kt to Q B 3, the Vienna Opening is the result. The Q Kt does not act immediately, but rather seems to relinquish the advantage of the first move; but this is only apparently so. For in all Openings the Q Kt plays an important rôle, and, having this piece in play, White soon resumes the attack, and with increased vigour in certain variations.

The defences for Black are—2. ... B to B 4; 2. ... B to Kt 5; 2. ... Kt to Q B 3; 2. ... Kt to K B 3. The latter yields the most satisfactory results. 2. ... Kt to Q B 3 may lead to the Steinitz Gambit, a difficult game for both sides; whilst 2. ... B to Kt 5 is the least satisfactory variation of all.

In this variation it is not advisable to take the offered Gambit pawn, though Black might have done so if he had played 2. ... Kt to Q B 3 instead of 2. ... Kt to K B 3.
