If you play transfers over 1MX, does the 1NT bid now become a transfer to ♣? If yes, then how do you show a suitable 1NT response hand after the X? You can't use the 2NT bid to transfer to a single suited ♣ hand as it will most likely be misinterpreted. Neither can you bid 3♣ as that would now be interpreted as a fit jump. Passing seems like a poor option if partner has a good hand.
We do the full number:
1S (X) XX=any nt response 6+ or a single-suited game force.
1H (X) 1S=any nt response 6+ or a single-suited game force ---even (including long spades)
1H (X) XX=a 1S response (6+).
1M (X) any suit jump shift is an invitational splinter (10-12 support points including the distribution).
The other transfers have a range of nothing to 12.
1S (X) XX (P)...Opener passes with any full opening bid, but completes the NT relay or bids a new suit with weakness (not suitable to defend).
We still have Jordan 2NT (LR +) and regular double jump splinters. The inclusion of XX in the structure is what allows everything.
