@FischerTal: 

I hope that you will learn a lot about Staunton Gambit. If you will experience some problems with opening the base, send me a email.

If you don't have Fritz or other Chessbase program, or Chessbase 8 or 9, then please download free Chessbase reader. 

YOU WON'T REGRET DRKODOS 

Kindermann's book is really excellent.
You can also have a look at New in Chess' Yearbook 85 (2007). There is an intersting article about the "early dutch sidelines".

I searched for Dutch Defence games in TWIC 700 between players rated over 2500, and found the following game:

Atalik,S (2597) - Gurevich,M (2607) [A87]
ch-TUR Ankara TUR (4), 26.03.2008

1.c4 f5 2.d4 Nf6 3.Nc3 d6 4.Nf3 g6 5.g3 Bg7 6.Bg2 0-0 7.0-0 Qe8 8.d5 Na6 9.Rb1 c6 10.b4 Bd7 11.dxc6 bxc6 12.b5 cxb5 13.cxb5 Nc5 14.a4 h6 15.Nd4 Nfe4 16.Nxe4 Nxe4 17.Bb2 Rc8 (the first new move; instead the immediate 17...Qf7 had been played) 18.Qd3 Qf7 19.Nc6 Bxb2 20.Rxb2 Bxc6 21.bxc6 Rxc6 22.Bxe4 fxe4 23.Qxe4 Rc4 24.Qe3 Rxa4 25.Rb7 Re8 26.Qxh6 Re4 27.Qd2 Ra8 28.Qd3 Qe6 29.e3 Kf7 30.Rc1 a5 31.Rcc7 Re8 32.Rb6 Rd8 33.Ra7 Re5 34.Rb5 Rxb5 35.Qxb5 Rc8 36.Rxa5 Rc1+ 37.Kg2 Qe4+ 38.Kh3 Qe6+ 39.Kg2 Qe4+ 40.Kh3 Qe6+ 41.g4 Rc5 42.Qb4 Rc4 43.Qxc4 Qxc4 44.Kg3 d5 45.Ra7 Qb3 46.Kg2 g5 47.h3 Kf6 48.Ra6+ e6 49.Ra7 e5 50.Ra6+ Kf7 51.Rd6 Qc4 52.Kf3 Ke7 53.Rh6 Qe4+ 0-1

A good win by Gurevich in a line I had considered slightly better for White. As it turns out, 12.Qb3! scores very well in practice and indeed looks at least slightly better for White.

I have both Andrew Martins video and his booklet on anti dutch systems.

Without exception, all old sources on anti-dutch systems are out of date. Only 3 books, touch the critical anti-Dutch systems, Kindermann (Leningrad System), Beim (Understanding the Leningrad Dutch) and McDonald (Starting out the Dutch Defence)

McDonald has a nice and quick introduction into the Dutch. Kindermann is most decent in giving an anti anti-Dutch reportoire. And Beim is a good addition with additional idea's to the Kindermann reportoire.

So if you want to play the Leningrad, the choice is simple. Buy Kindermann, and if you have money left, Beim is nice also.

If you want to play another system, it is hard. No single book gives you a reliable reportoire, so you need a mixture of books.

In my opinion, there is no good anti-Dutch book available, which gives an up-to-date overview of all lines.

1 Nf3 f5 2 d3 is awkward, if you are surprised behind the board. I always avoid the 1 Nf3 tricks by 1 Nf3 d6 2 e4 (or d3) c5 and I play a Najdorf. On other moves I play f5 and a Leningrad dutch.
