Observer article 9/ch/1997
Fame at last! In an alleged book review in the Observer (Books p16), Jay Rayner writes about a "man called Bob"
(one of my many pseudonyms) in whom "a lot of people have shown an interest". Read and ponder!

Perhaps the Chinese curse "may you live in interesting times" could be re-worded into "may you be considered an
interesting person". Infamy, infamy, they've all got it in for me!

1.e4 e5 2.Bc4 Ke7 3.d3 Kf6 4.Nc3 g6 5.Qe2 Qe7 6.Bd2 Bg7 7.Qf3# 1-0
spend only 2 minutes looking at it, so I guess it can be done faster

6 moves is possible, in at least 3 reasonably distinct ways:

1 d4 e6 2 Qd2 Ke7 3 Nc3 Kf6 4 Nf3 g6 5 g3 Kf5 6 Qf4# 1-0
1 e4 e6 2 Nc3 Ke7 3 Bc4 Kf6 4 Qf3+ Kg5 5 d4+ Kh4 6 Qh3# (or 6 g3#) 1-0
1 d4 f6 2 e4 Kf7 3 Qd3 Kg6 4 e5+ Kh5 5 Be2+ Kh4 and White can now mate
in several different ways on move 6

5 moves is possible too:

1 e4 f6 2 Nf3 Kf7 3 Bc4+ Kg6 4 d4 Nc6 5 Nh4+

I'm not sure if 4 moves is possible and still satisfying the condition.
