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!;-) Terry
