1.d4 f5 Diagram

okay.. now i gots mah MCO-13 from 1990.. just in case anybodies out thar who don't.. but I don't need it to mention that this is the Dutch Defense.. something I don't know too much about, although I play ..f5 in the Queen's Indian here and agin2.g3 [ 2.c4 Nf6 3.g3 e6 4.Bg2 Be7 5.Nf3 0-0 6.0-0 d5 7.Nc3 c6 is given in MCO-13 as "the Stonewall Formation."

OOPS!! and 5Nh3!!! {:D woe, hold the fone, nelly!] 2...d5 3.c4 e6 4.Bg2 c6 [ 4...Nf6 5.Nf3 c6 6.0-0 Bd6 is one position given in MCO-13] 5.Nh3 Bd6 Diagram

6.0-0 [ Something that jumps to my mind to exploit this "weirdness" in the position is 6.c5 Bc7 white avoids it, and it is hard to say the relevance. In my experience, I guess a large pawn wedge like this can be good, but often black just busts it open for good counterplay. 7.Nc3 a5 perhaps could prepare ..b6 at some point.. but Fritz says 8.Bf4 Nf6 9.0-0 0-0 10.Bxc7 Qxc7 I'm not sure what is going on] 6...Nf6 [ 6...Ne7 7.Bf4 Ng6 8.e3 0-0 9.Nd2 Nxf4 10.exf4 dxc4 11.Nxc4 Bc7 12.Ng5 h6 13.Nf3 Nd7 14.b4 Nf6 15.a4 Nd5 16.Qb3 b5 17.Nce5 Qd6 18.Rfc1 Bb7 19.Nd3 a5 20.Nc5 Rfb8 21.Ne5 bxa4 22.Rxa4 Bc8 23.Ncd3 Nxb4 24.Nxb4 Rxb4 25.Rxb4 axb4 26.Nxc6 Ra6 27.h4 Rb6 28.Ne5 Ba6 29.d5 Bc8 30.h5 Kh7 31.Ng6 Qd8 32.Re1 exd5 33.Bxd5 Bd6 34.Bf7 Bd7 35.Re8 Qxe8 36.Bxe8 Bxe8 37.Qe6 Ba4 38.Qxf5 b3 39.Ne7+ Kh8 40.Qf8+ 1-0 Kirilov,V-Vatnikov,J/Vilnius 1949/MCD (40); 6...h5 7.Bg5 Be7 8.Bxe7 Qxe7 9.Nf4 Qf6 10.h4 g5 11.hxg5 Qxg5 12.Nd2 Nf6 13.Nf3 Qg7 14.Qc2 Ne4 15.cxd5 exd5 16.Nxd5 Na6 17.Nf4 Bd7 18.Nh4 0-0-0 19.d5 Kb8 20.dxc6 Bxc6 21.Ne6 Qe5 22.Nxd8 Rxd8 23.Rad1 Rg8 24.Qc4 Rg7 25.Qd4 Qxd4 26.Rxd4 Rf7 27.Nxf5 Nac5 28.Bxe4 Nxe4 29.Nd6 Rd7 30.Rxe4 Rxd6 31.Re7 Rd2 32.f4 h4 33.gxh4 Rd8 34.Kf2 Be4 35.Rxe4 1-0 Vaher,A-Bogdanov,R/Estonia 2000/EXT 2003 (35)] 7.Nd2 [ 7.Bf4 0-0 8.Nd2 Qe7 9.Qc2 Ne4 10.Rad1 Nd7 11.f3 Nxd2 12.Rxd2 Nf6 13.Bxd6 Qxd6 14.e4 fxe4 15.fxe4 e5 1/2-1/2 Harzer,P-Klein,H/Bad Laasphe 1994/EXT 99 (15); 7.b3 0-0 8.Bb2 Qe7 9.Qd3 b6 10.Nd2 Bb7 11.f3 e5 12.dxe5 Bxe5 13.Bxe5 Qxe5 14.e4 fxe4 15.fxe4 dxc4 16.Qxc4+ Kh8 17.Nf3 Qxe4 18.Nd4 Qe3+ 19.Kh1 Ba6 20.Qb4 c5 21.Qe1 cxd4 22.Qb4 Nbd7 23.Rfe1 Qc3 24.Qa3 Rae8 25.Rec1 Qa5 26.Qd6 d3 27.b4 Qe5 28.Qc6 d2 29.Rd1 Qxa1 30.Rxa1 Re1+ 1/2-1/2 Rowland,A-Januszewski,M/Frankfurt 1998/EXT 99 (30)] 7...0-0 8.Nf3 Nbd7 9.Nf4 [ Fritz wants to play 9.Bf4 Qe7 a) 9...Bxf4 10.Nxf4 Qe7 (a) 10...dxc4?? 11.Nxe6) ; b) 9...dxc4?? 10.Bxd6; 10.Bxd6 Qxd6 11.Nf4 dxc4 It seems plausible to trade off dark squared bishops for white, while moving the knight to a better square, though here Fritz thinks he can get away with taking the "Queen Gambit" pawn.] 9...Qe8 10.Qc2 Ne4 11.Nd3 Qh5 [ Fritz keeps suggesting 11...dxc4 12.Qxc4 Nb6 13.Qc2 Nd5 I like it.
