B30: Sicilian: 2...Nc6 3 Bb5, lines without ...g6
1.e4 c5 2.Nf3 Nc6 3.Nc3 e5 4.d3 g6 5.Be3 d6 6.Be2 Bg7 7.a3 [7.0-0 Nge7= ]
7...Nge7 8.Qd2 White's setup hasn't been terribly ambitious [8.Nd5 Nxd5 9.exd5 Nd4= ]
8...0-0 9.Bh6 a6 10.Bxg7 Kxg7 11.h3 b5 12.0-0 h6 13.Bd1 Be6 14.Ne2 f5 15.Ng3 f4 16.Ne2 g5 17.Qc3?! [17.Nc3 Nd4=/+ ]
17...a5 I'm definitely trying to have the best of all worlds here - with pawn rollers on both sides of the board [17...Ng6 18.Nh2 h5 19.f3-+ ]
18.b3? [>=18.Qd2=/+ ]
18...Ng6-+ 19.Qb2 [19.Qd2 h5 20.h4 Nxh4 21.Nxh4 gxh4 22.Kh1-+ ]
19...h5 20.Nh2 g4 21.g3 gxh3 22.gxf4 [22.c4 fxg3 23.fxg3 Qg5-+ ]
22...Nxf4 23.Kh1 Kh6?! the whole was to use the king as a defender of the h5-pawn, but it would have been better to avoid pins on the c1-h6 diagonal [23...Kh7 24.Qc1-+ ]
24.Nxf4 Rxf4 [24...exf4?! 25.c3-/+ and the the queen would influence the 2nd rank]
25.Qc1 Qf6 26.Rg1 Nd4 27.Rg3 [White can consider shedding a pawn here 27.c3 Nxb3 28.Bxb3 Bxb3 29.Qe3-+ ]
27...Rc8 I'm not sure what the point of this move was?? [27...Kh7 28.c3 h4 29.Rg1 Nxb3 30.Bxb3 Bxb3-+ ]
28.Rb1 [28.Qe3 Kh7 29.c3 h4-+ ]
28...Rc7 [28...b4 29.Qe3-+ ]
29.Qe3?! [29.c3 Nc6-+ ]
29...Rg7?! I was struggling to figure out how to improve the position [>=29...b4-+ ]
30.Rxg7?! [>=30.c3 h4 31.Ng4+ Bxg4 32.Rxg4-/+ ]
30...Qxg7-+ 31.Qg3 Qf6 I shouldn't be avoiding the queen trade, but I was trying to buy myself some time to try to understand the resulting endgame - we were both low on time here [31...Qxg3 32.fxg3 Rf2 33.c3-+ ]
32.Qe3 [32.f3 Qg5 33.Qf2 Rf6-+ ]
32...Qh4 [32...Qg6 33.Qg3 Qxg3 34.fxg3-+ ]
33.Qg3 [33.c3 Qg5 34.Qg3-+ ]
33...Qf6 [33...Qxg3 34.fxg3 Rf2 35.c3-+ ]
34.Qe3 Bd7 [34...Qg5 35.Qg3-+ ]
35.c3 Ne6?! maybe technically this isn't really that bad, but from a practical sense it would have been [>=35...Qg5! 36.Qg3 (36.cxd4?? Qg2# ) 36...Nc6 37.Rb2-+ ]
36.Be2 [36.Qxh3 Rh4-+ evaluates no better for White than anything else in Fritz, but it would re-establish material equality and hope!]
36...Ng5 37.Rg1? [>=37.f3-+ ]
37...Rxf2 38.Rxg5 Rxh2+ 39.Kxh2 Qxg5 40.Qxg5+ [40.Qf2 Qg2+! 41.Qxg2 hxg2 42.Kxg2-+ Bg4 43.Bf1 b4! 44.axb4 axb4 45.cxb4 cxb4 46.Kf2 Be6-+ and the b-pawn falls]
40...Kxg5 this endgame is an easy win for me
41.Kg3 h4+ 42.Kh2 Kf4 43.Bf1 Ke3 44.Bxh3 Bxh3 45.Kxh3 Kxd3 46.b4 axb4 47.cxb4 cxb4 48.axb4 Kxe4 49.Kxh4 Kf3 50.Kh3 e4 51.Kh2 e3 52.Kg1 e2 53.Kh1 after making this move White resigned 0-1
