Wait a minute. Wasn't Capablanca able to do that?

Capablanca's dead, baby. Capablanca's dead.

Sometimes, mates in eight are fairly obvious -- say because it's
effectively mate in three but the loser can keep making suicidal
interpositions to delay the inevitable. In this case, though, the
mate is by no means obvious: my copy of Fritz 8 takes a couple of
minutes to find a mate in 12. (I think it's interesting that Hans Ree
claimed in 1999 that `computers find this in a second'[1]: mine
certainly doesn't and, while it's not so hot by modern standards, it's
a hell of a lot faster than a 1999-vintage machine. My guess is that
Ree's computer found a mate in eight fairly quickly but that there is
actually a defence to it.q)
