I got burned in 1985 for tuning on a vax and playing on a Cray, and barely found this problem after round two of the 1986 WCCC tournament. I try to 'play' on what I 'test' on when possible now. IE I would definitely feel more at ease playing anyone using my quad xeon, as opposed to a 16-way alpha machine.
