  [Event "Horsham Club Championship"]  [Site "Horsham"]  [Date "2015.10.27"]  [Round ""]  [White "Mansson, James C"]  [Black "Harbott, Peter"]  [Result "1-0"]  [Eco "D15"]  [Annotator "Mansson, James C"]  [Source ""]   1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.Nf3 Nbd7 {?!} {This is rather passive.} 5.cxd5 {!} { White exploits Black's move order by heading for a version of the Slav Exchange where Black's knight is passive on d7 rather than active on c6.} cxd5 6.Bf4 a6 7.e3 e6 8.h3 {By providing an escape square, White can maintain the bishop on the b8-h2 diagonal.} Be7 9.Bd3 b5 10.Ne5 Nxe5 11.dxe5 Nd7 12.O-O { White has an active position, while Black is somewhat passive and kingside castling is unattractive because of the bishop on d3. Black's main plus point is the potential weakness of the White pawn on e5.} Qc7 {?!} {This not a good square for the queen, which comes under attack down the c-file and along the b8-h2 diagonal.} ( 12...Bb7 {was suggested by Peter after the game.} ) 13.Rc1 ( 13.Nxd5 exd5 14.e6 Ne5 $10) Qb8 {?!} {This allows a neat combination.} ( 13...Qb6 {was more solid, but White has pressure on the kingside, e.g. via} 14.Qg4 ) 14.Nxd5 {!} exd5 15.e6 Ne5 ( 15...Bd6 16.Qh5 $20) 16.Qh5 Bf6 ( 16...Bd6 17.Bxe5 Bxe5 {transposes to the game.} ) ( 16...Bxe6 {giving back the piece was better, although after} 17.Bxe5 {White is on top.} ) 17.Bxe5 Bxe5 ( 17...Qxe5 18.Rxc8+ {!} Rxc8 19.Qxf7+ Kd8 20.Qd7# ) 18.Qxf7+ Kd8 19.e7+ {My opponent admitted after the game to missing this move.} Kd7 20.e8=Q+ Kd6 21.Rc6# 1-0
