Go up one level in this thread

Somebody has their story backwards.  Fritz 7 could not find it after 30 minutes.
 However here is the analysis of Hiarcs 8.  It finds Rxd4 in 6 seconds and never
lets go.  This on a 1.4G Athlon Thunderbird.  However none of the programs that
like Rxd4 see any reason to resign 5 moves later.
