The Bishop is better placed now at B 2. At R 4 it was, owing to the changed
position, less useful. At its new post it strengthens the centre.
... 13. P to Q 4
Black anticipates White's possible P to Q 4 by himself advancing.
14. Castles 14. P takes P
15. P takes P 15. Kt to Q sq.
Black now executes the manoeuvre which was suggested at his ninth move. But
it is not so good at this stage. The position is now as shown in Fig. 7.
