1.Nf3 d5 2.c4 c6 3.d4 Nf6 4.Qc2 g6 5.e3 Bf5 6.Qb3 Bxb1? {The move is dubious on positional grounds as it gives up the bishop pair to an undeveloped piece. As it turns out it simply looses material as well.} 7.Rxb1? {recapturing automatically thus missing that white can throw in the zwishenzug 7.Qxb7!} Qc7 8.cxd5 Nxd5 {giving white a central pawn majority and leaving the a2-g8 diagonal open while white has an unopposed LSB is quite dangerous, although allowing white rapid access to the c file and pressure on the c6 square is also unpalatabe} 9.Bd3 Bg7 10.Bd2 O-O?! {It would have been more accurate to have started with ...Nbd7 as that would keep castling options open and develop another piece.} 11.h4!? {After a long think. with the bishop pair and central pawn majority white can take a more positional approach to try for an advantage. However with black lacking a LSB, whites rook being on h1 and black lagging in development plus the chance for rapid central advances this approach become rather tempting.} Nf6 12.e4 h5 13.e5 Nd5 14.e6 fxe6? {Blacks best try was f5 with the possibility of counter chances.} 15.Bxg6 Qd6 16.Bxh5 Nf4? {First 16..Nd7 (developing) before committing to counterplay for the 'sacrificed' pawn.} 17.Bxf4 Rxf4 18.Qxb7 Bxd4 19.O-O Rf8 20.Nxd4?! {not as strong as simply taking the rook} Qxd4 21.g3? {Qxa8 instead is decisive. not that it matters too much as white is winning quite handily in either case} Nd7 22.Rbd1 Qe5 23.Qxd7 {(Rxd7!)} Qxh5 24.Qxe6+ Rf7 25.Qxc6 Raf8 26.Qd5 Qh6 27.Qg5+ Qxg5 28.hxg5 {#r}
