LIFE Master AJ: A briefly annotated game:
Nikolay Popov – Anatoly Karpov
Leningrad, USSR; (R#6) / 1967
1.e4 e5; 2.Nf3 Nc6; 3.Bb5 a6; 4.Bxc6 dxc6;
5.0-0 f6; 6.d4 exd4; 7.Nxd4 c5; 8.Nb3 Qxd1;
9.Rxd1 Bd6; 10.Na5 b6; 11.Nc4 Be7;
12.Bf4 Be6; 13.Ne3 Bd8; 14.Nc3 h5;
15.Ncd5 Rc8; 16.h4! c6; 17.Nc3 c4!?; 18.a4,
OK, but ...
<[Better was: 18.Ne2! c5; 19.Bd6, ±.]>
18...Ne7; 19.Bd6 0-0; 20.a5 b5; 21.Bc5,
<[RR 21.g3, ]>
21...Re8; 22.Ne2 Ng6; 23.g3,
<[Better was: 23.Ng3 Nxh4; 24.Nxh5; "~" (unclear) with active piece play. ]>
23...Bg4!; 24.Nxg4 hxg4; 25.Rd7!?, <(♘c3)>
25...Rxe4; 26.Nc3 Re5; 27.Bb6 b4;
<[RR 27...Bxb6; 28.axb6 Rb8; 29.Rxa6 Re1+; 30.Kg2 Ne5; 31.Re7 Nf3; 32.Ne2, '=' - Fritz 13. ]>
28.Na4 Be7; 29.Rad1 Re2?!;
This looks slightly suspect.
<[ Better was: 29...Bf8! =]>
Missing a big opportunity.
<[ Better was: 30.Kf1! Re5; 31.Ra7, ±]>
30...Bf8; 31.cxb4 Ne5; 32.Kf1 Rc2; 33.Rd8?, (>/= ♖a7! )
33...Rxd8; 34.Rxd8 Kf7; 35.Rd1!?,
<[RR 35.Be3 Bxb4; "~" - Fritz 13. ]>
<[ Better was: 35...Bxb4!; - Fritz 13. ]>
Now 36.b3 was best, according to the iron monster.
36.Bd4? Bxb4; 37.Nb6 c5; 38.Bc3?, (>/= 38.♗e3 ♘e5)
Good enough to get the job done.
<[ But better was: 38...Rxf2+!; - Fritz 13. ]>
39.bxc3 Rxf2+; 40.Kg1▢,
(This was the only legal move.)
White is lost ...
Behind a couple of buttons, resignation is even an option here.
The rest is not that interesting ... and it is close to being "best play" for both sides.
41.Kg2 Ne5; 42.Na4 Rd3; 43.Rc1 Rd2+; 44.Kf1 Ra2; 45.Nxc5 Rxa5; 46.Ne4 Ke6; 47.Ke2 Nd3; 48.Rb1 Re5; White Resigns.
