I was pleasantly surprised to see two reactions on my post from februari.

@Dji
I think 25....Qh6 has never been played in this position. But that doesnt mean it's not an acceptable move. In fact I think black can reach equality as well, provided he is willing to take on an endgame with two rooks against Queen.

@Markovich@
Well in the period 1995-2000, I got something like 80% anti-marshalls, thematic tournaments excepted. This was probably the influence of Kasparovs preference. However this percentage has decreased to something like 60%. So 2 real marshalls out of 5, which is acceptable to me.
Only this month won two real marshall games as black.

[b][color=#006633]The Marshall attack etc., etc..


Congratulations on a nice win.  It shows well how to exploit White's theoretical mistake on move 22.  I'm curious to know what proportion of the time do your opponents play into the Marshall.

The Marshall attack is one of the most heavily analysed variations in the Spanish.
However it is perfectly playable in correspondence games, where the jungle of variations
can be sorted out at ease. A good example on the deep preparation in correspondence chess
is Timothy Hardings recent contribution in his Kibitzer column for www.chesscafe.com this month.

In this post I will show you another deep preparation, and a Novelty on move 25!


Malushko-Micawber, corr. 2006/2007

[b]1.e4,e5 2.Nf3,Nc6 3.Bb5,a6 4.Ba4,Nf6 5.0-0,Be7 6.Re1,b5 7.Bb3,0-0 8.c3,d5 (marshall)
9.xd5,Nxd5 10.Nxe5, Nxe5 11.Rxe5,c6 12.d4,Bd6 13.Re1,Qh4 14.g3,Qh3
15.Be3,Bg4 16.Qd3, Re8 17.Nd2,f5 18.f4,g5 19.Qf1,Qh5 (pawnpush variation)

20.Qg2 (best);gxf 21.Bxd5,xd5 Now whites best continuation is 22.Qxd5+

(a) 22….Kg7 23.Bxf4,gxf 24.gxf,Kh8!
    Subscribers to the e4/e5 section can find a deep analysis of this position.
    The conclusion seems that black is OK



Is there some analyse about 25.Nf1  25...Qh6     ?
  

Eternity it's very long especially towards the end!

9.xd5,Nxd5 10.Nxe5, Nxe5 11.Rxe5,c6 12.d4,Bd6 13.Re1,Qh4 14.g3,Qh3
15.Be3,Bg4 16.Qd3, Re8 17.Nd2,f5 18.f4,g5 19.Qf1,Qh5 (pawnpush variation)

20.Qg2 (best);gxf 21.Bxd5,xd5
(diag)





[i]{Now whites best continuation is 22.Qxd5+

(a) 22….Kg7 23.Bxf4,gxf 24.gxf,Kh8!
     Subscribers to the e4/e5 section can find a deep analysis of this position.
     The conclusion seems that black is OK
(b) 22… Kh8 23.Qxd6,fxe 24.Rxe3!! (24….,Rxe3?? 25.Qxf8+) }


22.Bxf4?           (white loses a tempo)
22........ Bxf
23.Qxd5+, Kh8
  (black has achieved Kg8-Kh8 in one move, where in var [a] he needs two)
24.gxf, Be2!
25.Nf1
(diag)




In fact the game started here, both white and black playing fairly quick
The first game reaching this position in fact ended here: Dely-Pogats, 1961, Hungary, 0.5-0.5


25……..Bf3   26. Ng3,Qxh2+ 27.Kxh2,Bxd5 28.Re5 with an unpleasant endgame.
Although judged equal by both Nunn (1989) and Anand (1993)
Simmelink-Farinas, internet 1998, 0.5-0.5 (58)
Moeslle-Yefeerov, corr.1994, 1-0 (38)

25……Bxf1! My own recommendation to T. Harding in 2000 with the intention
                      26.Rf1,Re2! = or 26.Rxe8,Rxe8 27.Rf1,Qe2! 28.Qf3,Qxb2 unclear

25……..Qg4+ 26.Ng3?,Re3! 27.Qg2,h5 28.Qf2,Rf3! 29.Qxe2? (better Qg2), Rxg3!+
Corjeda-Jaime, corr. 1993, 0-1
This game gave me the idea to reach the position after move 27 by transposition,
as 25…Qg4 is refuted by 26.Qg2! exchanging queens.
__________________________________________________
_________________________
25……. ,Rg8+N          This natural move is in fact a novelty
26.Ng3  , Qg4           This is the attacking scheme I proposed even with a temp down!
                                      26.....Re3 is refuted by 27.Qxg8




27.Qg2?,                  Here white started thinking for the first time,
                              but his natural move is in fact an error
                              White should have forced a draw with 26.Qc6!, Re3/Re4 27.Qf6+
27……..,  Re4!            My original intention 27…Re3 is also good  transposing to
                              Corjeda-Jaime above.
                              Looking at the position again this seemed even more convincing!
                                       Note that both moves prevent white to play for a draw with Qc6
                             (27...Re3 28.Qc6,Rgxe3 winning)         

28.a4     ,                 White’s natural break, but what else?
28……. ,  h5               Black carries on with his plan, intending h4. White seems unable to
                              take any effective countermeasures.
29.axb   ,Bf3!           White resigned!! (diagram)
