- 2NT can no longer contains fit in shown major. With stronger hand GIB could pass through cuebid overcall or bid game directly. So 2NT is adjusted to 3rd in shown major and 4+ in other major. With 3-3 in majors GIB would bid directly 2NT as invite instead of double. It shows actually 3+ 3+ as minimum is 43 least in random major, but as unclear which is yet is provided like 3+ 3+.
Why should allow 4+ in other major? With 5 in one major and 11-12 points, not 4+ cds in 2 majors , IMO it should free bid 2s here instead of double. So I think should show exactly 4 spade, not 4+ spade.
Also, why should it show 3 of opener's hearts? with say 4=2=4=3/4=2=3=4/4=1=4=4 shape I can imagine bidding double, 2nt. I think 2nt should show 4 spade 3- hearts (not 3 exactly hearts), 11-12 hcp, stop clubs.
