which only furthers Black’s development. White would only be justified in this course if he could now win a pawn with 8. PxP, but Black would win it back and have the superior game after
8. … P-Q5 9. Kt-K4 Castles
followed by B-B4 and Q-R4ch. The correct move in this variation is consequently 6. B-B4, and a possible continuation would be: Kt-KB3; 7. P-K3, B-K3; 8. R-QB1 or B-QKt5 or B-Q3.
With this we will close the discussion of the variations initiated by 2. P-QB4, P-K3, and study the reply 2. … P-QB3. The first question which arises in our mind is: Which file will Black be able to utilise for his Rooks? An attempt to free the King’s file through P-K4 is conceivable. But White can prevent this by simply playing Kt-KB3.
Two other possibilities present themselves: after playing P-K3, Kt-B3 and QKt-Q2, Black could steer into a line similar to the Queen’s gambit accepted with PxP and P-QB4, or he could keep the centre closed with P-KB4 and Kt-B3, with the intention of playing Kt-K5 and using the KB file for activating his Rook via KB3. Diagram 40 gives the position reached after:
3. Kt-KB3 P-K3
4. P-K3 Kt-KB4
5. Kt-K5 Kt-B3

White would not accomplish much with 6. P-KB4. The more or less symmetrical lineup of the pieces would most likely lead to a draw after Black properly prepares freeing his hemmed-in Bishop with P-QKt3 and B-Kt2. A better plan would be 6. P-B3, preventing Kt- K5 and preparing the eventual advance of the King’s Pawn to K4. In reply to 6. … , QKt-Q2 White would then rather play 7. Kt-Q3 than exchange Knights, as after this exchange it would not be too difficult for Black to bring his Bishop into play on the King’s wing via K1. Both of White’s Bishops would be best placed on Kt2.
This “Stonewall” opening can also be played by White, who is then a move to the good in the variation just shown. But this opening has practically disappeared from modern tournament games, simply because the QB cannot easily be brought into play.
