This is the move usually recommended for the defence. Black may however adopt, 9. P. to K. R’s 3d, apparently with little disadvantage.

10.B. to Q’s 3d.10.K’s Kt. to K’s 2d.
11.P. to Q. R’s 4th.11.Castles.
12.R. to Q. R’s 2d.12.K. to R’s sq.
13.R. to K’s 2d.13.P. to K. B’s 4th.
The game is about equal.

Variation B. on White’s 9th Move.
WHITE. BLACK.
9.Q’s Kt. to B’s 3d.

We have long suspected that the force of this form of the attack has been vastly underrated. The following variations are taken from an able analysis by Mr. G. B. Fraser, of Dundee, who has kindly presented the result of his labours in the investigation of this attack at our disposal:—

9.B. to K. Kt.’s 5th.

This move is considered by all the modern writers on Chess to be Black’s best reply.

10.Q. to Q. R’s 4th.10.B. takes Kt.

In reply to White’s last move, Black may play either 10. Q. to Q’s 2d, or 10. B. to Q’s 2d, instead of the move in the text. If he adopt 10. Q. to Q’s 2d, White replies with B. to Q. Kt.’s 5th, apparently winning a piece. It has been suggested to us that perhaps Black’s best move is 10. K. to B’s sq., to which White might reply with K. Kt. to his 5th; and on Black’s moving K. Kt. to R’s 3d, advance the P. to Q’s 5th. (For B. to Q’s 2d, see [Variation A.])
