   [Event "Horsham Club Championship"]  [Site "Horsham"]  [Date "2016.4.12"]  [Round ""]  [White "Mansson, James C"]  [Black "Heath, Chris W"]  [Result "1-0"]  [Eco "E11"]  [Annotator ""]  [Source ""]   1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+ 4.Bd2 Bxd2+ {This line is rather passive. Black is better off defending the bishop, e.g.} ( 4...Qe7 ) ( 4...a5 ) ( 4...c5 {!?} ) 5.Qxd2 ( 5.Nbxd2 {seems less natural as White wants the knight on c3.} ) d5 6.Nc3 b6 7.cxd5 {This seems a good moment to exchange, as in the resulting "Carlsbad" structure, Black's ...b6 does not create a good impression.} exd5 8.e3 O-O 9.Bd3 Re8 ( 9...Bb7 {is more common.} ) 10.Qc2 Bb7 11.O-O h6 {?!} {This weakening of Black's pawn structure is a mistake, as now Ne5 gains force.} ( 11...Nbd7 12.Nb5 Ba6 13.Qa4 {is awkward for Black.} ) ( 11...Nc6 {is best, though after} 12.a3 {White is doing well in a superior "Carlsbad" position.} ) 12.Ne5 Ba6 13.Bxa6 Nxa6 14.f4 Ne4 {?} {This is just a blunder.} ( 14...c5 {should have been tried.} ) 15.Nxe4 dxe4 16.Qc4 {!} $20 {This is what Black overlooked. White wins material because of the double attack.} b5 17.Qxf7+ Kh8 18.Qg6 Qf6 19.Nf7+ Kg8 20.Nxh6+ Kf8 21.Qxf6+ gxf6 22.Rac1 {This endgame is naturally a clear win for White, who gradually improves the position of his pieces, before commencing the advance of his kingside pawns.} Re6 23.Nf5 Rd8 24.Rfd1 Rd5 25.g4 c6 26.a3 b4 27.Ra1 b3 28.Rac1 Rb5 29.Rc3 Nc7 30.Rdc1 Rb6 31.Rc5 Nd5 32.Kf2 Ne7 33.Nxe7 Kxe7 34.h4 Kf7 35.h5 Kg7 36.Kg3 {Black had seen enough and so resigned.} 1-0
