Suicide squeeze

There isn't much to this story, but I don't see a suicide squeeze every day so here it is:

		♠	J 9 6 5
		♥	Q 5 4
		♦	J 9 5 2
		♣	10 5
♠	Q 8 7			♠	K 10 3
♥	K 9 7 6			♥	10 3 2
♦	A 7			♦	Q 8 4 3
♣	Q 7 6 4			♣	A J 2
		♠	A 4 2
		♥	A J 8
		♦	K 10 6
		♣	K 9 8 3

I opened 1N and bought it. The defense started with a low club to the ace and jack. I won and continued the suit; LHO won that and played a 4th round, North and East both pitching hearts. I tried a heart and LHO won the king and continued the suit. I won in dummy, and ran ♦9 to LHO's ♦A. Another heart came back and RHO pitched a diamond without trouble. This is the end position:

		♠	J 9 6
		♥
		♦	J 5
		♣
♠	Q 8 7			♠	K 10 3
♥	9			♥
♦	7			♦	Q 8
♣				♣
		♠	A 4 2
		♥
		♦	K 10
		♣

With 4 in the bank for each side, I tried a low spade, and when LHO played the ♠Q the defense was finished. In practice, he cashed the long heart and squeezed his partner, but a spade or diamond would not have been any better. At this stage, the only winning defense is to let RHO win the ♠10 and continue with ♠K.
