It is still forcing
This hand occurred during a club game at matchpoints; I was West.
Isn’t that East hand beautful? It would be such a pity to have it go to waste.
My 2 hearts was our artificial negative: it showed less than 4 HCP or 1 King. I did not much fancy bidding 3 spades at my second turn, but thought it my duty since 3 clubs was forcing. Partner’s 6 spades ended what I thought was an efficient and fine auction. There was not much to the play. North cashed the Ace of hearts and switched to a diamond. I drew trumps and claimed, although I did have to ruff the club suit good.
I was somewhat astounded to find that we received such a good score on this deal. We played it on round 4, so it had only been played a few times by the time that we played it, but by then it was the top score EW. I did not think that we had done anything so wonderful to deserve it; to me, the auction and play were straightforward. Things changed somewhat; in the end, we received 21 out of 25 matchpoints. 5 of us were tied at 1430; 2 EW’s outscored us at 1460, obviously when NS forgot to cash their Ace of hearts. Take a look at the virtual traveller here. Notice all those EW pairs who played in 3 clubs and made 5 for +150. They almost certainly had the same start to the auction (up to the 3 club rebid) as we did, but then West passed. Clearly, those Wests looked only at their own measly collection and decided that this was not forcing. My recommendation is this: openers below game rebid (having opened 2 clubs) is still forcing for one more round. There are too many hands that opener can hold that he does not want to make a unilateral decision just yet.
