Well, the main idea is to try to lure some opponents into a different set-up of the Stonewall (e.g. with Knights already on Nc3/Nf3). I use a lot 'risky' move-orders that try to achieve positions favourable to me.
This move-order has one serious defect (the Bf4 variation), but it's a risk worth taking OTB, purely for practical/statistical reasons (i.e. not all Whites will play that against you).
..and a matter of taste - I take the Staunton seriously (maybe I'm not a great defender or theory learner), plus I want to be able to concentrate first on the Stonewall, then learn some Anti-Dutch, then return to the Leningrad. Having tried learning all of them at once did not worked for me in the past..
@tafl: yes, if you know your Anti- stuff well
Thank you chk, for your effort and prooving some of my statements right.
The Bf4-problem only occurs if you use the d5/e6/c6 move order excusively to get to the stonewall. In the position after 1.d4 d5 2.c4 e6 3.Nc3/Nf3 e6 White will play one of the following moves in 98% of your games:
4.e4 if 3.Nc3 - the Marshall-gambit - good knowledge necessary
4.cxd - no problem after 4....cxd and later Bf5, solving all usual QGD problems with the bishop
4.e3 Bd6 5.Bd3/Nf3 f5! - no 5.g4 available, the above mentioned good Stonewall version
4.Nf3/Nc3 f5? 5.Bf4! - in this position, f5 is not a good choice.
Because the waiting move 4.Bd6 is now met by 5.e4, Black has no other choice but playing Semi-Slav-Mainlines (4....Sf6) or the
"Noteboom variation" which I recommended above.
It is a lot of work, but worth it, because it is really difficult to play for white - and in the range < ELO 2000 you will rarely find a white specialist in this line. Theoretically, there is no advantage for White - even Schandorff in his new QG-book offers no clear way to a White advantage (like he does in most other variations). And while searching for it, he completely ignores the mainlines in the Noteboom - he will know why!
