The money or the slam

This exciting hand came up this week in a club session. I was North, playing teams, EW are vulnerable and I picked up this:

♠	A J 6 5 3
♥	A K Q 3
♦	-
♣	K 8 7 4

A nice hand no doubt and further improved when partner opens a strong club. I respond 1♥ showing a positive with 4⁺ spades and LHO bids 2♠! Doubled back to me:

South	West	North	East
1♣	Pass	1♥	2♠
X	Pass	?

I hate these decisions, you have no idea whether the player knows he's bid your suit. At first it looks clear to pass but if East has ♠KQTxxxx they may come to 6 tricks. Down two is a poor result compared to a round suit slam even at these colours.

South	West	North	East
1♣	Pass	1♥	2♠
X	Pass	3♥	Pass
3NT	Pass	4♣	Pass
5♣	Pass	?

Showing suits I finally locate our fit. Do I have a raise to 6? Given partners bidding he figures to be 1345 or 1354 with 15+ highs. Correct or not I raised and then sent back the double.

South	West	North	East
1♣	Pass	1♥	2♠
X	Pass	3♥	Pass
3NT	Pass	4♣	Pass
5♣	Pass	6♣	Pass
Pass	X	XX	End

The redouble is routine, if our opponents reach 6♣ undoubled it costs just 2 imps if we're down one and gains 5 if we make. How do you proceed on the ♠9 lead?

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