It was called ICAC (International Competition in Analytical Chemistry) and it was held in other places as well. In early-mid-eighties thrice in Hungary - twice in Veszprem and once in Szeged. At least, that's the three times I was there. If memory serves me well I finished fourth in Veszprem in '83 or '84 (we took second place as a team), but I am not sure about details.
But no, I don't have questions, even if I had some of them. Three moves equals one house fire, and I moved more than thrice.
