Ratings listed are those at assignment on March 14, 1991. end date : 09/30/1991 D06 Queen's Gambit Marshall's Defense (by transposition - 5.d4)

1.Nf3 Nf6 2.c4 d5?!
An all too-common error. As I have said before, when challenging the c4 P, Black must preface ...d5, with ...e6/c6 or wait for White to play Nc3.

3.cxd5 Nxd5
[3...Qxd5 maybe better.]

4.e4 Nb6 5.d4 e6
[5...Nc6 6.d5 Wu - Azzarello : Checkmate Ch. 2009 6...Nb8+/- ]

6.Nc3
[For 6.Be3 see Tomkovich - Cole : Kenilworth Ch. 2007.]

6...Be7 7.Be3 0-0 8.Bd3 N8d7
[>=8...Nc6 9.0-0 f5+/= ]

9.a4
>= 0-0, here (+/-) or next.

9...a5 10.Qc2N c5
[>=10...Nb8+/= retracting.]

11.Nb5 cxd4 12.Bxd4 h6?
This unnecessarily weakens the K-shelter. [>=12...e5!? 13.Be3 (13.Nxe5 Bb4+ 14.Nc3 Nxe5 15.Bxe5 Nd7 16.Bg3 Nc5 17.Bb5 Be6 18.0-0 Bb3 19.Qe2 Qd4+/= ) 13...Bb4+ 14.Ke2 Rb8+/- ]

13.Rc1?!

[>=13.0-0+- ]

13...Bg5?
[>=13...Bb4+ 14.Ke2 e5! 15.Be3 Qf6+/- looking to unwind with ...Rd8 & ...Nf8.]

14.Nxg5 Qxg5
This makes the Q a target. [I expected 14...hxg5 ]

15.0-0 e5 16.f4?
This exploits the overloaded Nd7... [... However 16.Be3 Qe7 17.Rfd1 was much better.]

16...exf4[]
[Of course, 16...Qe7? meets with 17.fxe5 /\Nxe5? 18.Bxb6 ]

17.Qc7?
[>=17.Be2+- ]

17...Qd8?
[>=17...Nxa4 18.b3 Ndc5 19.Bxc5 Bh3 20.Rc2 Rfc8 21.Be7 Rxc7 22.Bxg5 Rxc2 23.Bxc2 Rc8 24.Bd1 hxg5 25.bxa4 Be6+/- ]

18.Qxf4+- Nf6 19.Qh4 Be6
Diagram

[>=19...Nfd7 20.Qg3 Qg5 21.Qxg5 hxg5 ]

20.Rxf6!
White wins a piece. [For if 20.Rxf6 gxf6 21.Bxf6 Qxd3 , 22.Qxh6 forces mate after 22...Qe3+ 23.Qxe3 Rfc8 24.Qg5+ Kf8 25.Nd6 Rxc1+ 26.Qxc1 ] 1-0
