The spectacular queen sacrifice

41. Qxh6!?

leads after its acceptance with

41...  gxh6

( 41... Qc5+! 42. Kh1 ( 42. Rf2 gxh6 43. e6+ f6 44. Nf7+ Rxf7 45. exf7 would win, if it werent for 45... Re1#! ) 42... Qxc4 with the threat 43...Qxf1++ seems to save Black! )

42. e6+

to victory for White in all lines.

42...  f6

( 42... Kg8 leads to checkmate immediately: 43. Nxf7+ Qxg3 44. Nxh6# )

43. Rxf6!

Uncompromisingly clearing the diagonal of the Bb2 - the threat is 44.Rxf8++!

43...  Kg8

After this the second player is only left with the choice of how she wants to be checkmated. ( The most stubborn defence was 43... Nxf6 44. Bxf6+ Rg7 ( 44... Kg8 leads after 45. Nf7+ Qxg3 ( 45... Ng6 46. Rxg6+ Kf8 ( 46... Kh7 47. Rg7# ) 47. Bg7+ Kg8 48. Bxh6+ Kh7 49. Rg7# ) 46. Nxh6# again to the familiar mate pattern with the three white minor pieces. ) 45. Nf7+ Qxf7 ( 45... Kg8 46. Rxg7# ) 46. exf7 - an astonishing pawn career - 46... Re1+ 47. Kf2 Rxb1 48. Bxg7+ Kh7 49. Bxf8 with a won endgame for White - amazing how quickly a full board can be swept empty! ) ( while no alternative was 43... Rg7 44. Nf7+ Qxf7 45. Rxf7 -+ )

44. Nf7+ Qxg3

( Following 44... Ng5 the most beautiful way is 45. Bh7+! Nfxh7 ( 45... Kxh7 46. Rxh6+ Kg8 47. Rh8# ) 46. Rg6+ Kf8 47. Bg7+ Kg8 48. Nxh6# )

45. Nxh6+ Kg7

( After 45... Kh8 there would have been another double check mate: 46. Rxf8#! )

46. Rg6#! 1-0
