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!MalushkoMicawber, corr. 2006/2007 1.e4,e5 2.Nf3,Nc6 3.Bb5,a6 4.Ba4,Nf6 5.00,Be7 6.Re1,b5 7.Bb3,00 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 (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 Kg8Kh8 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: DelyPogats, 1961, Hungary, 0.50.5
25……..Bf3 26. Ng3,Qxh2+ 27.Kxh2,Bxd5 28.Re5 with an unpleasant endgame. Although judged equal by both Nunn (1989) and Anand (1993) SimmelinkFarinas, internet 1998, 0.50.5 (58) MoeslleYefeerov, corr.1994, 10 (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!+ CorjedaJaime, corr. 1993, 01 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 novelty26.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 CorjedaJaime 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)
