Bristol countered by Novotny


In a recent chess game, the following position occured:

(= 11+11 )

D. Abel - E. van den Doel, Bad Zwischenahn, January 2011
White to move

The game continued with 22.Bh8! Sd4! 23.Bxd4 Rxd2 24.Qxd2 Qd5 and a few moves later a draw was agreed.

Would love to see some examples of this - Bristol countered by Novotny - from compositions.

Best,
Siegfried

Not to forget the Umnov effect ...
(This is from latest issue Schach 2011/3).

From an OTB view, what speaks against Rxd4 instead of Bxd4,
followed by Rd8 on Q-any, with a simple win? Just curious :-)

This win is so obvious. Probable explanation could be that c5 is a black pawn but then I cant find a reasonable previous move for black - was it RxSe2, but why?)

@Hauke and Seetharaman:

Black can defend with 23... Qf8.

i - Abel had prepared 20.Bf1 but forgot the move
ii - 23.Rxd4 Qf8 also should be equal
iii - 25.Be3 Qc6 is not better

(after Ilja Schneider; Schach 03/2011, p.54)

Obvious move is obvious. Wonder where I got my 2300 ELO. :-)

Thank you Bojan. I wrongly assumed that even after 23... Qf8 24. Rd8 is winning! My apologies to Siegfried.
