With south's hand-- how would you bid? At second chance to bid would you bid?
Me and partner were having a debate if 4D was the right bid. I was partial to bidding 4H (forcing me to pass or correct to diamonds), because I felt the hand was too good with approx 9 quick tricks to risk missing game for a 4 diamond partscore. Looking at South's hand, I see 9 tricks off the top-- if North has just one diamond or heart honor (or the ace of spades), and some support this hand is cold for game.
Here's the full deal:
(North)
♠ Q 7 6 4
♥ K 6 2
♦ 5 4 2
♣ 9 7 5
(West)
♠ A J 8 5
♥ Q 9 5
♦
♣ A 10 8 6 4 2
(East)
♠ K 10 9 3
♥ 8
♦ Q 9 8 6
♣ K Q J 3
(South)
♠ 2
♥ A J 10 7 4 3
♦ A K J 10 7 3
♣
It turns out par was to sacrifice 6H down 1 by South over a 6C contract by East/West. We got lucky somewhat-- West foolishly not bidding to the spade game (letting my get the 4D bid in), and the inability E/W to find their club fit at least let us get a positive score in a final contract of 4S down two. However, we were able to make 5H over them if South was declarer (we can be held to 4 if North declares).
I feel like one of the major problems we had was that even if E/W stopped bidding it was hard for North to convey support with such few points (and semi-long spades) without knowing the South was 6-6 with very solid suits at the 4 level, without South bidding game blindly.
