Rare Weapon against the Leningrad Dutch

GM Grigor Grigorov of Bulgaria was kind enough to send me the following interesting article, enjoy!
Hello dear reader!
I have the pleasure to introduce you in the extremely interesting Leningrad system in Dutch defense. The flexible pawn structure in this variation makes the arising positions very difficult to be analysed with a computer. One needs deep understanding in order to treat correctly such types of positions. That's why the Leningrad system is the favourite choice of creative players like Nakamura, Bartel and Malaniuk.
In the present article I would like to share with you my favourite weapon against this dangerous system. The variation that I am going to show you is not only positionally sound, but also it's less popular than the main lines. My practice shows that the majority of the players are not well prepared against this rare line. You can also seize the opportunity to cause nightmares to your opponents.

Ge2e4] Diagram [#] We have reached the main crossroad of this rare line. By
his last move white prepares the advance e2-e4 after which the rook will be
able to excerce pressure along the semi-open "e" file. I would like also to
emphasize on the fact that white hasn't played yet the move c2-c4 and and he
has the possibility to restrict the "g7" bishop by means of c2-c3.} Ne4 {The
main move in this position. Black takes radical measures against the pawn
advance. He wants to open the "f" file for his rook after possible exchange of
the knights. Before we continue it's necessary to take a look at other
possible continuations.} (7... Nc6 {[%cal Ge7e5] Very interesting idea. Black
not only prepares the e7-e5 advance but also increases the pressure over the
"d4" pawn. The main drawback of this move is that the knight is placed in
front of the "c7" pawn. As a consequence, the "c" pawn can no longer
participate in the fight for the center by c7-c6. Furthermore, as it will
become clear later, in some cases whis could use the restricted mobility of
black's Queen In genearal, you must think twice before placing your knight in
front of the "c7" (c2) pawn!} 8. e4 $1 {In order to use the "bad" position of

blockade of the "e5" pawn by means of Ng5-e4 and Be3. 2) exchange a pair of
rooks along the "d" file. 3) Launch a queenside expansion ( b2-b4, a2-a4 )

the missing pawns doesn't seem to be sufficient. His only decent idea is to

ressources to prevent this plan.} Rfe8 24. Kf2 Bf8 25. b4 $1 $18) (11... Qd7 {

their weakness on "e7" by playing e7-e5 as soon as possible. In order to
achieve this advance, he should remove his pieces from the long diagonal ( b6,

Despite of the fact that white's advantage is obvious, I would like to give
you some useful tips which will help you to convert your advantage in such
type of positions. As you could see, black has enough ressources to defend the
weakness on e7. That's why we should try to create a second weakness in
black's camp. In order to achieve that, we should take the following actions:
1) Exchange white-squared bishops by means of Be4 in order to make use of the
weakened "e6" square. 2) Place the rook on e6 while the queen should on e4.
3) Create second weakness on the kingside using h4-h5 pawn contact.}) 16. Bd4

to use that drawback, white could play b4 as soon as possible. Later he may
