If he holds a Queen, we loose 2 extra BB. If he does not hold a Queen, we win 1 extra BB. So, does he hold in Queen in less than 33% of the cases? I doubt it as there are many more QT combinations out there than KK combinations (though his play would fit KK better)

So I'd just call.

If someone has the guts to raise and fold to a 3-bet here with something like 99% certainty then this of course would be the best option.
