I first saw this position in 1989, I solved it as an excercise in mating
attacks.

I don't remeber my time, but Qh6+!! was my first inclination, then I worked
it out in a matter of several minutes.

I then gave it to my Mach III Master in Jan. 1990, it took it 2 min. 45 seconds
if I'm not mistaken.

Better time than me!;-)
