We play a fairly loose style and this is typified by our pre-emptive style. This was the first (Scottish readers who also played should note that I rotate hands for convenience):
Bidding 4♠ was the normal action although 3NT is the real winner. Sam lost the expected three trump tricks. [Update: Iain tells me that although Deep Finesse makes 10 tricks in 3NT, mere mortals only make 9 so 4♠ was fine]
Then I got abuse for my weak 2-bid, from Sam and the opponents!
2 Minimum suit, minimum points
Sam's 2NT is more an expression of joy than a useful bid. With no slam interest a straightforward 4♥ bid would give the opponents less information. The contract went one down when the club finesse failed, but scored very well as the opponents were generally making game in spades.
Not to be outdone, on the second board Sam opened 3♣ at Love All on the following:
This time it did not prevent the opposition bidding their cold slam.
We missed a slam on the final example, but I'm still happy with the bidding:
Things were not quite so simple at the table as the auction may suggest. When I bid 4♠ I knew that there was a chance that Sam would think that this was a void-showing jump, but I hoped that West's double and my spade length together meant that she would be too short in the suit to believe this. My fears were realised as she went into the tank, but eventually got the decision right! On a heart lead I played the spades correctly (ace then queen) to record 12 tricks. Slam is always there in clubs but too tough to bid after the takeout double.
We've now (sensibly) agreed that a jump to a four of a major is natural after a minor suit opening, whatever the interference.
