Lauria-Versace were the only ones who didn't get to 4♥ despite 2 pairs opening this in 3♣. The bidding [P]- pass - [1♦] wasn't a popular one and repeated only once, but East (Balicki) found a 1♠ in the same situation. Would you have found it?
I think this was an interesting deal both system and judgement wise. I don't know what 2NT meant, but double was presumably was some good ♠ raise. There was only one other pair who X-ed. It was already mentioned Balicki - Zmudzinski who had the same auction, but they ended up in 3♠, but it was still +6 IMPs. Most other pairs who bid 2N or 3♥ (Like Helgemo - Helness) ended up in 4♠-1. Some went went for more cautions immediate 2♠ (like Wijs - Muller and Nystrom - Upmark). I remember reading about this auction in Revision club and author gave quite good arguments why X should be some ♠ raise, interesting why other pairs haven't adopted the same treatment..
Let it be 3.
North basically has 12-14 balanced. In other tables bidding started also with 1N and 1♦. Helgemo-Helness faced auction in diagram and passed in tempo. Balicki faced [1♦] - 1♠ - [4♥] and doubled. At least one other pair faced [1♣]- 1♠ - [4♥] and bid 4♠. How do you plan to handle this hand?
