Black opts for this move, intending to remove white’s bishop from the a2-g8 diagonal, where it aims the weakest spot – f7 pawn.
White has a strong position in the centre; it should compensate the sacrificed pawn.
It seems that black started to underestimate white’s recourses. Black is lacking in development, thus the game opens in white’s favor.
10.exd5 Qxd5 11.Ba3!
Morphy immediately places his bishop on the most aggressive outpost, preventing black from further castling.
Black is attempting to cover the d5 square, though white’s initiative continues without any difficulties.
Other than the rook on f1 white has all his pieces in almost ideal positions, the question are how to continue?
A breakthrough at the most defended spot! White big lead in development permits him to sacrifice another pawn.
13… Bxd5 14. Nxd5 Qxd5
Finally all files are open. Black cannot prevent the loss of his Queen any longer.
and Black resigned as after 15…Kd8 just 16.Bc4 is curtains.
For instance : 16… Qd1 17.Rad1 Kc8 18. Re8 Mate!
