Hmm, it seems to me that the optimum forum meeting heights are now no longer at round thousands of feet, but rather at x200 or x800 feet, bearing in mind everyone here seems now to be adding or subtracting two hundred either way. Perhaps I’ll try harder to stay dead on the thousands from now on, seeing as most of you lot are now leaving that band well alone. 😉
As far as what to do in that particular instance, I couldn’t agree more with what everyone else has said; exercise your own judgement as captain (with a small ‘c’) of the aeroplane and do what you need to do to ensure separation. DO NOT assume the other guy has seen you. As Douglas Bader once said, “Rules are for the obeyance of fools, and the guidance of wise men.”
