This was a position from Hartston-Portisch at the Nice Olympiad in 1974 and is the last of our attacks on h6. There are several variations, so see if you can anticipate them.    

  1.Bxh6 gxh6 [Tougher, but also futile, was 1...Nb2 2.Bxg6 fxg6 3.Qxg6 Qf7 4.Qg4 Nc4 5.Be3 Nxe3 6.Rxe3 Rf8 7.Qh4 Qf4 8.Qe7 a5 9.Qxc5 a4 10.Rd3 a3 11.c4 dxc4 12.Rdxa3 Rxa3 13.Qxa3 and White has two pawns plus. White will force the exchange of the pieces and be left with a won king and pawn ending.] 2.Qxh6 Nb2 [Trying to get rid of the nasty bishop.2...Qe7 3.Ng5 Ncxe5 4.Qh7+ Kf8 5.Rxe5 Qf6 6.Bxg6 Qxg6 7.Qh4 Ke8 8.Nxf7 Qxf7 9.Rh5 and the black queen will be lost.] 3.Ng5 Nxd3 [3...f5 4.exf6 Nf8 5.Re3 The invaluable rook lift. It will be interesting for you to work out how it's a mate in 7 or 8, depending on how Black replies.] 4.Nh7  Black resigned as it's a mate in 4 or 5.
