Rated game, 20m + 3s Main Playing Hall, 10.08.2007
[Kmetz,Shawn]
1.c4 Nf6 2.Nc3 c5 3.g3 d5
Oddly enough as white I love to face this, as black I love to play it...
4.cxd5 Nxd5 5.Bg2 Nc7 The rubinstein ideally involves a reverse marcozy bind, c5, e5, Nc6 and ideally Ng8-f6-d5-c7-e6-d4! 6.Nf3 Nc6
7.a3 a move I was not familiar with. A reversed benko doesn't seem to offer much bite in this position so I continue setting up the bind.
7...e5 8.d3 Bd7 I think Be7 was better reserving judgement on where this bishop belongs. Qb3 is ever a threat and in such cases having this bishop on e6 might be better. 9.Rb1 f6
[9...Be7 10.b4 cxb4 11.axb4 Bxb4 12.Nxe5 is the idea I was worrying about, though it clearly doesn't work here due to the hanging knight on c3. 12...Nxe5 13.Rxb4]
10.0-0 Be7 11.Be3 Nd4
[11...0-0 12.Qb3+ Kh8 (12...Be6 13.Qxb7) 13.Qxb7 Rb8 is a nice trap that I wasn't sure of during the game since I kept looking at Qb3, Be6.]
12.Nd2
[12.Nxd4 cxd4 Hence, if white wished to remove my excellent knight, he must break up his bishop pair while the pawn structures look to lend themselves to an open games, or at least leave me with excellent bishops pointed at the queenside where the action appears to be happening. ; 12.Bxd4 cxd4 13.Ne4]
12...Bc6
[12...Rb8 would suffice, but it is not where I wanted my rook long term unless I planned to play b5.]
13.f3 [13.Bxc6+ Nxc6 14.Nb3 Nd4 leaves black with only one problem to solve, his depressing e7 bishop. but black can plan on playing Rb1& b4 or a kingside advance after 0-0 and f5.]
13...Nce6 14.Bf2 Qd7 The purpose was to secure my light aquares, but I think that e3, Nf5, Bh3! would really have accurately answerd this move. 15.e3 Nf5 16.g4
[16.Bh3 g6 (16...Nd6 17.Qb3 Kf7+-) 17.Qc2 Rd8 18.d4 cxd4 19.exd4 Nfxd4]
16...Nd6 17.Nb3 Nb5
[17...b6 18.d4 exd4 19.exd4 cxd4 20.Nxd4 Nxd4 21.Bxd4]
18.Na5 Nxc3 19.bxc3 Ba4 20.Qd2
[20.Rxb7 Bxd1 21.Rxd7 Kxd7 22.Rxd1 and blacks piece coordination will overcome the weakness of the c5 pawn thought the bishop pair is potentially dangerous. 22...Rab8 23.d4 cxd4 24.cxd4 exd4 25.exd4 Rhc8]
20...b6 21.Nc4 Rd8 22.Nb2
[22.Rfd1 Bb5 23.Nb2 Bc6 24.Nc4]
22...Bb5 23.c4 Bc6 24.Rfd1 Ng5
[24...h5 seemed an unecessary risk that would open up the light squares on my kingside to attack. 25.gxh5 (25.Bh3 hxg4 26.Bxg4) 25...Rxh5]
25.Qe2 0-0 26.h4 Ne6 27.Bh3 g5
preventing g5
28.h5
[28.hxg5 Nxg5 29.Bg2]
28...b5 otherwise white will have all the winning chances via a minority attack on the queenside.
29.Bf1 b4 30.axb4 cxb4 31.d4 giving my knight an outpost on f4 but gaining connected passed pawns... 31...exd4 32.exd4 Nf4 33.Qc2?
[33.Qe3 Rfe8 (33...Bd6 34.d5) 34.d5]
33...Bxf3 34.Re1 Qxg4+ 35.Kh2 Bd6 36.c5 Bc7 37.Bg3 Qxh5+ 38.Kg1 Qg4
[38...Nh3+ 39.Bxh3 Qxh3 40.Bxc7 Qh1+ 41.Kf2 Qg2+ 42.Ke3 Rde8+ (42...Rfe8+ 43.Kd3 Be4+ 44.Rxe4 Qxe4+ 45.Kd2 Qe3+ 46.Kd1 Qe1🙄 ;
38...Qh1+ 39.Kf2 Nh3+ 40.Bxh3 Qxh3 41.Kxf3 Qxg3+ etc.] 39.Kf2 Nh3+ 40.Bxh3 Qxg3+ 41.Ke3 Rfe8+ 42.Kd2 Qf2+ 43.Kd3 Qxc2+ 44.Kxc2 Be4+ 45.Rxe4
[45.Nd3 b3+ 46.Kd2 Ba5+] 45...Rxe4 46.Bf5 Rexd4 47.Rh1 Rd2+ 48.Kb3 Rh2 49.Rf1 a5 50.Be6+ Kg7 51.Nc4 Rd3+ 52.Ka4 Ra2+ 53.Kb5 b3 54.Nd6 Bxd6 55.cxd6 Rxd6 56.Bxb3 Rb2 57.Ka4 Rd4+ 58.Ka3 Rxb3+
59.Kxb3 the rest, is a matter of technique. 🙂
59...a4+ 60.Ka3 Kg6 61.Rb1 h5 62.Rb6 h4 63.Re6 Kf5 64.Re2 g4 65.Rf2+ Kg5 66.Rg2 f5 67.Rh2 h3 68.Rh1 Kh4 69.Rg1 g3 70.Rf1 Kg4 71.Rg1 g2 72.Re1 h2 Warren56 resigns 0-1
