You arrived in a somewhat ambitious slam after North opened a 12-14 NT. After your 2♠ transfer (showing clubs) West doubled, and eventually you took your chance in 6♣.
West leads ♠A and switches to ♥9. The contract is not exactly laydown, but it's not hopeless either. Plan the play please.
Experienced single dummy solvers are kindly requested to use hidden text and let as many as possible get the chance. Thanks.
