[ICU-BridgeSoc] Weekly Problem

This problem is designed by me, Mr. Yan and Mr. Zhou from Fudan University Bridge Club. W N (Yan) E S (Zhou) 1D / 1NT 2S / 3S / 4S // S: Q8 H: J107 D: Q854 C: AJ74 S: AJ107632 H: A96 D: K C: 93 Lead = C10 (I've rotated this board to let the lower hand be the declarer, and the top hand be the dummy, thus the left-hand side opened 1D). In fact, the auction ended at 2S (which is expected), but we found that this 4S is very interesting and worth playing. Try your best to make this contract ! This is the penultimate weekly problem of Imperial College Bridge Club 2024-2025. Tianxiang Fu (Jacky) Vice President (2024-2025)
