Subject: Very very tough test position for Rybka, Nikolic vs Fischer 1968

I posted the position of Nikolic vs Fischer 5 years ago in this forum and no
program can find Fischer's 19...Bg4!! even if you let all the programs compute
for several days.

The position is sound because I let the computer play the position and black
always win even if both white and black engine asses the position as winning for
white.

Now 5 years after with several times faster hardware and emergence of strong
programs and improved old programs, Can any program find Fischer's 19...Bg4 !!

 Nikolic,E - Fischer,R, Vinkovci 1968
