I am currently rearranging this blog into a "book" format. This is change is ongoing, so not all parts are working yet. However, most of these links work

Hi Ben,
The link to XYZ over 1-minor still seems not to work. The link on the right (XYZ over 1M) does work, but the text starts all the way at the left of the page.
Best,
Han
Thanks Han
I fixed the link (obviously xyz is over 1 minor opening only, as 2C after 1M is Riton, and 2D is weak non-forcing). Hopefully the page lines up correctly now and the both links work.
Coming soon, Multi-versus-Multi, responding to takeout double, simplified Kantar Roman Keycard Blackwood, the remainder of Equality.
Obviously, xyz is still in effect after 1H - 1S - 1NT.
The problem I imagined I saw was after interference. You said that xyz was off after responder passes. Since I like to play negative free bids and I thought I saw negative free bids used in other areas of your book, I believe xyz should still be on after partner passes. Even an aution like:
1D, (1H) P (P)
Dbl
qualifies for xyz, x=1D, y=P, z=Dbl.
Responder has lots of choices. Pass would be for penalty. 1S would show 4 spades and less than 8 points. 1NT would suggest playing in NT and promise a heart stopper. 2C would be a puppet to 2D and would almost certainly be weak. 2D would be at least a 1 round force asking more information about openers hand. The auction could end in 3D. 2H would be an invitation to game in NT if opener has heart stoppers. 2S would show 5+ spades and invitational values too good for a negative free bid. Finally 2NT would be Lebenshol.
Admittedly, this makes things a bit more complicated but playing negative free bids never made the openers job easy. In an auction such as that shown above, opener is virtually forced to double. He could also bid 1S with 4 spades and extra values or 1NT as a balancing bid and not necessarily showing extra values but probably at least a partial stopper. After either of these bids, xyz should still apply.

I forgot to add, Ben, that I really like your writeup of xyz and really appreciate the many examples you have given throughout your book. I know it isn't easy to find appropriate examples.
