"DarkThought" avoids Nxf3 after less than 10 seconds and locks onto Rxf3 instead. The change of mind is due to the fact that "DarkThought" sees one of the Pawns queening after Rxf3 (fail high) while it does not see any progress for Black after Nxf3 (score stays at around +6). So, it does _not_ spot the draw after Nxf3 because the perpetual is just too deep. =Ernst=
