(1) Sherer,Max (1688) - Moldovan,John (1812) [E23]
Kenilworth Summer Tournament Kenilworth, NJ (1), 12.06.2009
[Moldovan & Rybka 2.3]
E23 Nimzo-Indian Defense
Spielmann Variation (4.Qb3)
[This was supplanted by the less-exposing, center-focusing 4.Qc2
(my opponent's choice in our last Nimzo debate) decades ago but has the B-attack & surprise value in its favor.]
[The Milner-Barry-like Zuerich Variation, 4...Nc6
, was a good alternative.; 4...a5
; & 4...Qe7
should also be fine.]
[This is the main line. Here are some others from my practice :
(via transposition) 6.dxc5
Hoffman - Moldovan : Springfield 06/13/1999 10...a6=
; - 5.a3
proel - Moldovan : G/15, Buho21.com 10/13/2006 7...Bxc3+
; & finally - 5.Nf3
guestkqkw - Moldovan : G/15+5, jeu.echecs.com 04/14/2008 /\11.Nxe5?
(! Horowitz) was an option.]
[A necessary reinforcement. 6.a3
can be met by 6...Nd4=
I'm already on my own & at a crossroad. Had this been a correspondence game, I would have taken a few days here to check my references & compare lines.
Alas, in OTB play, there's no luxury & the decision musy be made in minutes.
[In Play The Nimzo-Indian (Permagon, 1985), Gligoric says this "pushes White's Q back to a better square" (it does & also loses time) and recommends 7...Nxd2
with "a satisfactory and flexible position.)
However, Alekhine & Tartakower preferred the text. They said NxB would give White "strong pressure on the open file" & "chances on the d-file."]
! Horowitz 9.a3
Botvinnik - Myasoyedov : Leningrad 1930]
is most common & has scored very well (72% from 25 games). But, Rybka says 12...a5
[Black has to secure the e4 square for his Nc5 at some point & he probably needs ...f5 to do so. But delaying it until White has played a3 is more precise & 9...b6
makes keeping the fP at home & controlling e4 with 11...Ne7!?
[There have been 2 games with 10...b6
; & 1 with 10...Qe7
[This breaks-up White's B pair but without the Ne4, the d6 square will be, as noted on move 7, weak & vulnerable. 12...b6
>= ...Qe7, here or next.
[In addition to the aforementioned Qe7, also >=14...Qf6
would've saved a tempo.]
[This sets a trap, which Max falls into, but 17...Rac8+/=
was best; despite he fact that White can really put the squeeze on.]
[This loses an Exchange. He should' ve played 18.R1d5
Rybka; or 18.c5+/-
I didn't want to give up the minor exchange but allowing Nd4 /\ Nb5-d6 would've been too troublesome.
[I looked at 23...Rc5=/+
but missed that 24.e6?
can be met by 24...Kf8-/+
After this move, I spaced-out & didn't realize it was my turn until 3 minutes had elapsed!
was a better try.]
[This lets me force a trade of Rs. >=35.fxe5
White offers a draw.
would have won.]
Black offers a draw... White accepts.
Time left - Sherer 15:48, Moldovan 4:09
Estimated time used - Sherer 43:17, Moldovan 54:51
Longest think by White - 4 minutes for 26.Bf3.
Longest think by Black - 9 minutes for 22...Bxf3!
Not a good way to start the event but I'm just a half-point back & there are 12 weeks (possibly 24 games!) left.
