(1) Kernighan,Mark (2249) - Moldovan,John (1809) [A47]
4th Sy Fish Memorial Kenilworth, NJ (3), 20.10.2011
[Moldovan & Houdini 1.5a]

40 moves in 45+5, then SD/15+5 (delay) A47 Queen's Indian Defense London System

1.d4 e6 2.Nf3 Nf6
[A switch from the 2...f5 I played on Sunday in Westfield and something new in our series.]

3.Bf4
! Prié

3...b6
[3...c5 /\ ...Qb6; & 3...Bd6!? are other ways to play.]

4.e3
[For 4.h3 ?! Prié 4...Bb7 (4...Ba6 ! Prié 5.g4!?N ) 5.e3 Be7 see my US15P07 win vs. Pitter & Minkov - Sherer : Kenilworth Ch. 2008.]

4...Bb7 5.Nbd2
[For 5.Bd3 (! Prié) see my opponent's 2008 KST win vs. Sherer.]

5...c5
[5...Nh5 ! Voronkov; For 5...Be7 see my 2009 GSCL loss to Fernandez.]

6.Bd3
[6.h3 is most accurate. As a London rule of thumb, White should answer ...c5 or ...Be7 (possibly ...d6, as well), whichever comes 1st, by making a retreat at h2.]

6...cxd4
Another rule: When the enemy's b-Knight has been commited to d2, Black should trade Ps at d4.

7.exd4 Be7
...Nh5 = was best here and at moves 8-10.

8.0-0
Again >= h3, here or on the next 2 turns.

8...0-0

9.Re1 d6 10.c3 Nbd7
[For 10...Re8 see Kernighan - Mangion : Fish Memorial 2010]

11.h3
[For 11.Nc4 see Fernandez - Stoyko : GSCL 2009-10]

11...Re8
[RR: 11...Qc7 12.a4 a6 13.Bh2 Rfe8 14.Qb3 Bf8 15.Re2 Bc6 16.c4 Qb7 17.Rae1 d5 Kamsky - Carlsen : Tal Memorial Blitz, Moscow 2008]

12.Bh2 Nf8
[12...a6 , /\ completing the Hedgehog setup with ...Qc7 and ...Rac8, before choosing between Stoyko's ...Nf8 approach or Dzindzichashvili's ...Bf8 method, is more flexible.]

13.a4 a6 14.Ng5
[>=14.a5 b5 15.c4+/= ]

14...Ng6
[>=14...Nd5 ]

15.Nde4
[>=15.Ndf3 ]

15...Nxe4 16.Nxe4
Diagram

16...Bxe4?!N
After a rather long thought, I decide to swap my good B for Mark's pesky N and trade-off my inferior d.s. B. [>= Kernighan's 16...Nh4!= , which I never considered,; 16...f5 17.Nd2 Olejarczyk - Przybylski : Warsaw 2010 17...Bg5!= , which I missed,; 16...h6= ; & 16...Qd7= ]

17.Bxe4 d5 18.Bd3
[‹18.Bxg6 hxg6= ]

18...Bd6 19.Bxd6 Qxd6 20.g3
This prevents ...Nf4 and prepares to attack a6 with Qe2.

20...a5
Anticipating White's plan, I push my a-pawn out of harm's way.

21.h4 Nf8
Another pro-active move. 22.h5 N moves 23.h6 would have loosened the dark squares around my K.

22.Kg2
[‹22.f4 Nd7= ; & 22.h5 h6= ]

22...e5 23.Bb5
This gains a tempo but takes the B out of play. [>=23.Rxe5 Rxe5 24.dxe5 Qxe5 25.Qb3+/= ]

23...Re6 24.dxe5 Rxe5
Diagram

25.Rf1
Looking to take advantage of his lead on the clock (12 minutes to 6:47) and keep the game complex, my foe goes against conventional idP wisdom and avoids a trade of Rs. [>=25.Qd2 Rxe1 26.Rxe1 Rd8 27.Rd1 /\Ne6 (27...Qc7= ) 28.Bc4!+/= ]

25...Qc5
This stops White from hitting d5 a 3rd time, with the opportunistic 26.Bc4.

26.Qd2 Rd8 27.Rad1 Ne6
Black's pieces are very well placed now and are ready to support ...d4 which, once the back-rank weakness is addressed, dissolve the isolonus.

28.b4
This gains another tempo but makes my d-pawn a passer.

28...axb4 29.cxb4 Qd6 30.f4?!
[>=30.Rfe1 ]

30...Re4 31.f5
[>=31.Rb1= ]

31...Nc7
Diagram

32.Rb1?
[>=32.Bd3 Rxb4 33.f6=/+ ]

32...Nxb5 33.axb5 f6?
This stops the aforementioned f5-f6... [... But >=33...d4-+ ]

34.Rfe1 Qe5 35.Qf2 d4-/+
Black offers a draw. White accepts. Game drawn by agreement. Time left - Kernighan 0:11, Moldovan 3:15 Estimated time used - Kernighan 47:49, Moldovan 44:40 Longest think by White - 4 minutes for 15.Nde4 and 21.h4 Longest think by Black - 12 minutes for 16...Bxe4 1/2-1/2
