They all want 36.-Nc7. Solved instantly by Tiger, Junior (even J5), Shredder (even S3) and CM (though some newly created personalities might need more time). Also Yace finds the correct continuation after less than 1 minute. Appearantly this knowledge is missing in F6/DF. For the latter I aborted the analyse after 10 min, though.
