In NT they take four diamonds and a club, in clubs they can start and continue trumps to hold you to ten tricks. 4♥ looks pretty good, however. If, say, they start with a trump you win the ace and play the king of spades, tossing a diamond regardless of East's play. This looks like ten tricks. Can we get there by plausible bidding?
This hand has a 17 count, better than the last, but this time I have a void in partner's responding suit, a discouragement. Rightly or wrongly, I bid 2♥. Our auction went
1♣ 1♠
2♥ 2♠
3♣ Pass
The good news is that I cannot legitimately make 5♣ (Opponents started by cashing two diamonds, and I took eleven tricks, but...), the bad news is they cannot stop a 4♥ contract.
Perhaps?:
1♣ 1♠
2♥ 3♣
3♦ 3♥
4♥
Trusting again that over 3♣ opener will bid 3♠ if he has three, responder shows clubs. The clubs obviously could be better but there are three and responder has decent values opposite a reverse. Opener temporizes with 3♦ and responder shows a good three card heart holding. Opener, hearing that responder has spades, clubs and hearts decides that 3NT on four diamonds to the jack is not wise and bids the game in hearts.
Is this all too far-fetched?
FWIW, 3♣ making 5 scored -1.33 imps. There were some tables making game contracts in both NT and in clubs. No one on the score sheet was playing 4♥.
Added: On the actual auction, I do not think that my 3♣ bid shows a sixth club (as was mentioned with the previous hand). At that point there is no reason to think that respnder holds anything better than, say, KQTxx/ Txx/ Qx/ xxx. With such a holding he will respond 1♠, he will rebid 2♠ over 2♥ and he will most happily drop 3♣.
