9...d6 10.Bf4 h6 11.h4 Qe8 12.d5 Na6 0-1 Jones,B-Depasquale,C/Suncoast 1999/CBM 68 ext (35) Black gets a version of the main line Leningrad, with White's Queenside pawns doubled and hence immobilised.]

10.c5+ Kh8 11.cxd6 exd6 12.Bg5 Qc7 13.Bf4! # No rest for Chris! The Bishop on g5 will get hit by h6 anyway so John works on the d6 weakie instead. h6 14.h4 Qe7 15.Qa3 Rd8 16.Rfe1 Qf6 17.e4 fxe4 18.Rxe4 Bf5 19.Re2 Na6 20.Qb3 Nc7 21.Ng5!! # Crushing move! White's minor exchange sacrifice is valid because he has maximised his development. Black can only watch helplessly as White's pieces invade at will. hxg5 22.Bxg5 Qf8 23.Bxd8 Rxd8 24.Rae1 Bc8 25.Re7 Ne8 26.Rf7 Qg8 27.Be4 d5 28.Bxg6 Nd6 29.Rc7 Rd7 30.Qd1 Qd8 31.Rxd7 Qxd7 32.Qh5+ Kg8 33.Qh7+ Kf8 34.h5 Ne4
