G/55 + :05 increment A35 English Opening Symmetrical 4 Knights

1.Nf3 Nf6 2.c4 c5 3.Nc3 Nc6 4.e3 d5
[For 4...g6 see my 2009 draw vs. I. Zhurbinskiy.]

5.cxd5 Nxd5 6.Bc4
[>=6.Bb5 as in my 15th USCCC Prelim draw vs. Marthinsen (in various databases, including chesslive.de) & my 2005 STCC clincher vs. KillerQueen (Checkmate Compilation file).]

6...e6
[RR6...Nb6 7.Bb5 Bd7 8.0-0N g6 9.d4 cxd4 10.Nxd4 Bg7 11.Nxc6 bxc6 12.Be2 0-0 13.Qc2 Nd5= Moldovan - Macaspac : G/4+2, Rahway 06/01/2010 (14) Moldovan - Macaspac : G/4+2, Rahway 06/01/2010]

8.b3N
[8.d4 is the norm but I didn't want the Panov CK/ Semi-Tarrasch IQP position that results from 8...cxd4 9.exd4 ]

8...Bf6 9.Bb2
This takes care of c3 but doesn't get me anywhere. [Perhaps 9.Ba3!? /\Nxc3 (9...Ndb4 10.Qb1 0-0 11.Bb2 b6 12.a3 Nd5= is an option; but 9...Qa5 10.Bb2+/= helps White.) 10.dxc3 Qxd1 11.Raxd1 b6 12.Nd2! Bxc3? (12...Bb7 13.Ne4 Be7 14.Nd6+ Bxd6 15.Rxd6 Ke7 16.Rdd1 Rhd8= is correct.) 13.Ne4 Be5 14.Bxc5! bxc5 15.Bb5 Bb7 16.Nxc5 a6 17.Ba4 0-0 18.Rd7+/= was worth a try.]

9...a6
[9...Nxc3 10.Bxc3 (or 10.dxc3 0-0 (10...Qxd1 11.Raxd1+/= ) 11.Qc2 b6 12.Rad1 Qc7= ) 10...Bxc3 11.dxc3 Qxd1 12.Raxd1 Ke7 13.Ng5 h6 14.Ne4 b6 15.Bb5 Bd7 16.Rd2 Ne5= was also okay.]

10.Qe2
Played to keep Qs & Bs on. [10.a3 would have allowed Black to simplify with 10...Nxc3 11.Bxc3 Bxc3 12.dxc3 Qxd1 ]

10...b5 11.Bd3 Bb7 12.Rac1
Diagram

Bringing the QR into play, in case the Bd3 has to retreat to b1.

12...Qe7?
This overloads the lady. [12...0-0= was right.]

13.Be4?
[13.Nxd5 exd5 14.Bxf6 gxf6 otherwise White wins the c5P 15.Nh4+/- would have messed-up Black's K-side.]

13...0-0-0?
The Q-side is too drafty for the K. [Dan should have played 13...Rd8= followed by ...0-0.]

14.a3?
Too slow. [>=14.a4 ]

14...Bxc3?
Why give-up the good B? [14...Kb8+/= ]

15.dxc3 f5 16.Bc2
[16.Bb1 /\Na5 17.Ba2 seemed too artificial but I could have continued with Ne5 & c4.]

16...Qf6?
Putting the Q opposite the d.s. B is asking for trouble. [16...Nf6+/- ]

17.Rb1??
Diagram

[17.Bd3+- was the right way to protect b2... but I was worried about weakening b3.]

17...e5??
[We missed 17...Nxc3 18.Qe1 (18.Bxc3 Qxc3 19.Rfc1 Qf6 20.a4 maybe better) 18...Nd4! when 19.exd4 (19.Nxd4 Nxb1 20.Bxb1 cxd4 21.Bxd4 ; 19.Bxc3?? Nxf3+ 20.gxf3 Qg5+ 21.Kh1 Bxf3# ; 19.Qxc3?? Ne2+ 20.Kh1 Nxc3-+ ) 19...Nxb1 20.Qe2 Nxa3 21.Bxa3 cxd4 nets Black a R & 3P for 2 minors.]

18.c4 Nc7 19.cxb5
[>=19.Nxe5! Nxe5 20.f4 winning a P.]

19...axb5 20.Rfc1?
Again overlooking Nxe5!, etc.

20...g5??
Diagram

[20...Qe6+/- , getting off the Bb2's line, was best.] Now White wins:

21.Bd3 g4?
[>=21...Rhf8 22.Bxb5 g4 23.Ne1 Qd6 ]

22.Ne1
[>=22.Nxe5! Nxe5 23.Rxc5 Rd5 24.Rbc1 Rxc5 25.Rxc5 Re8 26.Bxb5 ]

22...Ba6?
[22...b4 was a much better try.]

23.Rxc5 h5?
[>=23...Rd5 ]

24.Rbc1 Rh6
& Black resigned without waiting for my reply. Time left - Moldovan 23:55, Komunicky 9:25 Time used - Moldovan 33:05, Komunicky 47:35 Longest think by White - 6 minutes for 14.a3? Longest think by Black - 8 minutes for 22...Ba6? [After 24...Rh6 25.Rxc6 Qxc6 26.Rxc6 Rxc6 27.Bxf5+ White emeges with a Q+B & 2Ps vs. 2R.; >=24...Bb7 ] 1-0
