None vul, my partner deals:
1NT (2NT) X (3S)
X (4C) X (4D)
P (P) X AP
1NT was 10-12, 2NT wasn't alerted (Intented as minors), nothing was asked and they had no specific agreement of UNT over our NT. (Although no contradicting agreement)
2NT bidder held Kx x Qxxxx KQxxx or alike. I'd assume he used UI when bidding 4C.
3S bidder had 5 card support for Ds and 4D was a make for 14 swing.
