I just enjoyed the way this auction could look superficially natural if you squint hard enough, despite the fact that every single NT bid was artificial
2N opening showed 5+-5+, Spades and either hearts or clubs (nominally 10-13 points, same playing strength as Fantunes 2-bids)
3N shows slam interest in whatever my second suit is
4D is a cue for hearts
4N is RKCB
5N is even KC count with a working void
