| 13. | Q takes B: ch. | 13. | K to R sq. |
| 14. | Q to K 2 | 14. | B takes P, and wins. |
Not 5. ... Kt takes P, which would be met by 6. P to R 5, with a winning attack. And not 5. ... P to Q R 4, which is inferior to the text move, and weakens the pawns on the Queen's side for the End game.
| 6. | Castles | 6. | P to Q 3 |
| 7. | P to B 3 | 7. | Kt to B 3 |
| 8. | P to Q 3 | | |
The position is now equivalent to the Giuoco Piano, except that White has advanced his Queen's side pawns, which is a slight disadvantage.
