Thanks for the question, I will probably deal with it in more detail in my Feb update (which I hope will be online before the end of this month!), but here is a quick answer:
     In short: yes, I think White should be very happy with the doubled d-pawns and open lines! Smiley
Apart from the Watson game, on my databases White has a near 100% score from this position, and the reason is that Black wastes a lot of time with his knight bringing it to the poor square on a6. In order to free his game he is obliged to play ...c6xd5 at some point which dissolves the doubled pawns, and allows the white knight to d5. The game Gil Reguera,J (2310) - Servat,R (2460), Orense op Orense (4), 1997, is a good example: 1 c4 e5 2 g3 Nf6 3 Bg2 Nc6 4 Nc3 Bb4 5 Nd5 Bc5 6 e3 Nxd5 7 cxd5 Nb4 8 d4 exd4 9 exd4 Be7 (9...Bxd4 loses as in a Spraggett game) 10 a3 Na6 11 Ne2 0-0 12 0-0 c6 13 Bf4 cxd5 14 Nc3 d6 15 Nxd5 Be6 16 Re1 Re8 17 Nxe7+ Rxe7 18 Qh5 d5 19 Bxd5 Bxd5 20 Rxe7 Qxe7 21 Qxd5 etc. Remember that White was significantly out-rated here, too!
     If Black plays this way a move later, then White's best is to play 9 d4 exd4 10 exd4 and simply transpose.

...Nxd5 and ...Nb4 in the 3 Knights System

I originally sent this question via email to GM Kosten. Any one else wishing to contribute is more than welcome. Here it is:

Dear GM Kosten,

I purchased your book, "The Dynamic English" and I'm also
a subscriber to Chesspublishing.com.

I have a few questions about a particular 2-move sequence
that troubles me in the English.

In your book (Chapter 4 The Three Knights System: 4...Bb4),
you give the following variation:

1 c4 e5 2 g3 Nf6 3 Bg2 Nc6 4 Nc3 Bb4 5 Nd5! Bc5 6 e3 0-0
7 Ne2

and then as a subvariation, there is a continuation

7... Re8 8 0-0 Nxd5 ("as ever, tactical tries tend to
rebound against Black") 8 cxd5 Nb4?! 10 d4!

and I can certainly see that this variation is to White's
advantage.

However, what if Black decides to play ...Nxd5 followed by
...Nb4 earlier?

For example, the game Watson-Enkhbat, U.S. Championship,
Seattle, 2003 went this way:

1 c4 e5 2 g3 Nf6 3 Bg2 Nc6 4 Nc3 Bb4 5 Nd5! Bc5 6 e3 Nxd5

(not covered in your book, but there is a game at your
website with that move, Christiansen-Charbonneau, Richmond,
Canada, 2002. However, in that game, Charbonneau played
7...Ne7, instead of 7...Nb4)

7 cxd5 Nb4 8 d4 exd4 9 exd4 Be7

and I can't say that I'm a big fan of the doubled d-pawns.

In a game of mine, Black played the ...Nxd5, ...Nb4 later than
in the Watson-Enkhbat game, but earlier than mentioned in your
book. It went like this:

1 c4 e5 2 g3 Nf6 3 Bg2 Nc6 4 Nc3 Bb4 5 Nd5 Bc5 6 e3 0-0
7 Ne2 Nxd5

(again, the move is not mentioned in the book,
but there is a game at your website, Balashov-Najer, Elista,
2000, that continued that way. Again, Black chose to play
8...Ne7, instead of 8...Nb4)

8 cxd5 Nb4

and here I played the meek 9 d3 which gave me a passive game.

9 d4 seems appropriate here but, as in the Watson game,
White would end up with doubled d-pawns: 9... exd4 10 exd4

What is your opinion of the early ...Nd5, ...Nb4, and what
would you recommend against it? Is White to be satisfied with
the doubled d-pawns?

Thanks in advance.
