Save the Queen

---Another deal from 22nd European Youth Championship which needs a bit care not much.

Me holding:

♠Q4
♥KJT93
♦Kx
♣AQxx

My partner opened 1♠, I bid 2♥ and he 2nt meaning 15+ balanced. I thought that slam is cold and bid 5nt to choose a slam and last bid was 6♥ from my p.

N-----E-----S----W
1♠-----p----2♥----p
2nt----p----5nt---p
6♥-----All pass

After 9 of ♦ both hands:

♠AKT98------♠Q7

♥A87---------♥KJT96
♦Axx---------♦Kx
♣xx-----------♣AQxx

At first sight it seems that contract is safe when Q of trump is found. I played J of ♥ and let North win with Q and after he returned ♣ I have realized that I was asked 2 big questions which are ; is J of ♠ is falling? or finesse works? Because if I get 5 spades I have 5+4+2+1 12 tricks however if I get 4 tricks from spades I have 12 tricks with ♣ finesse.

I would have come up with solution if I had thought in a proper way that is clear that if I loose ♥ finesse to LHO I can still try ♣ finesse if ♠ is not good. When I lost J of ♥ to RHO and forced for a ♣ finesse I got it with ace and cashed ♠ honours which was 4-1 ♠ break for a down 1. And in the closed room it was played 4♥ making 6.
