Two speeds

Playing a casual teams match I picked up a really good hand:

♠	J 8 7 2
♥	Q J 3
♦	J 9 7
♣	Q T 7

Favourable and as dealer partner opened 1♥. My RHO overcalled 2♦ and anxious to convey the true nature of my hand I passed.

This is what came back:

South	West	North	East
1♥	2♦	Pass	2♠
3♣	3♠	?

Interesting, bidding into our opponents strong auction without any help partner actually has a hand. Better own up to our two queens:

South	West	North	East
1♥	2♦	Pass	2♠
3♣	3♠	4♥	4♠
5♥	X	End

Blast! With all this defence surely we wanted to defeat their vulnerable game rather than take our chances at the five level.

	♠ J 8 7 2 ♥ Q J 3 ♦ J 9 7 ♣ Q T 7
♠ Q 4 3 ♥ T 5 ♦ A K Q 6 5 ♣ A 4 2		♠ A K T 6 5 ♥ 9 2 ♦ T 8 4 2 ♣ 8 3
	♠ 9 ♥ A K 8 7 6 4 ♦ 3 ♣ K J 9 6 5

Shows what I know. Their game is not only cold but they should have bid five over five because that makes as well. We concede a mere hundred for finding the profitable sacrifice. How did things go over at the other table:

South	West	North	East
1♥	X	1♠	4♠

Two very different speeds.
