  Chessical: Poschauko's winning combination is unsound, but Donner does not see the flaw.

Donner could have played: <19... Rxe3!> 20. Rxf7+ Qxf7 21. fxe3 Be7 22.Bg5 when the 3 pawns will struggle to make up for the Rook.

Donner obviously believed that <21...Rg8> was safe and sufficient, but overlooked the mate after:

<22. Bg7+!> Rxg7 23. Qh6+ Kg8 24. Qxg7 mate

Dec-20-09  zanshin: Yes, in retrospect <21...Rg8?> set up the mating net. Necessary was something like <21...Bf4> but there are still plenty of traps in the position.
