Concealing a 5-card major with 5332 and minimum values made the crucial difference on deal 1 of the first Swiss match. This was the deal:
I haven't got the full layout (hand-dealt) but LHO had Qxxx in trumps and Kx in H. We bid:
1D - 1S
1NT - 2C
2D - 3NT
1NT was 11-13 and 2C followed by 3NT showed choice-of-games with 5332. West now chose to lead the king of H and when he continued the suit, 4S came home for +620. At the other table the auction started 1H-1S and Mårten led a diamond for a painless +100.
Was this a random positive result for this treatment or did we deserve a swing due to a better systemic approach?
Put me down for no 2.
