Another Scotch with 0-0-0 for Black

GJB vs CW
=========

1.e4 e5
2.Nf3 Nc6
3.d4 ed
4.Nxd4 Nxd4
5.Qxd4 b6
6.Bc4 (hoping that my opponent will play c5 and then I follow with Qd5 threatening mate or Qxa8)
6. ... Bb7
7.0-0 Qe7
8.Nc3 0-0-0
9.Bf4 Qc5
10.Qd3 (it is certainly not to White's advantage to trade queens in this position)
10. ... f6
11.Nb5 (the win of a pawn 'threat' is simple...)
11. ... Bd6
12. Bxd6 cxd6
13.Nxd6+ Kb8
14.Nxb7 (I have the option of winning the exchange in this position but opt to remove a defender of the Black King)
15.Bd5+ Kb8
16.Qa6 Qc7
17.Rad1 Ne7
18.Bb3 (again I don't want to encourage a potentially powerful knight from joining the game by swapping off!)
18. ... d6 (moving the Knight would surely have been better?)
19.Rd3 Qb7
20.Qa3 Qxe4 (a pawn grab ... )
21.Rxd6 Qb7
22.Rd1 Rc8
23.Rd7 Rc7?? (unfortunately a blunder due to ... Qxe7)
24.Qxe7 (Black Resigns)
