You have arrived in 4♠ as East. It would have been better to let West declare, but that can't be helped. At least you have avoided the killing heart lead. South leads ♦9.
Your worries are not over because you can see that ♥A is offside. Is there a chance even if the opponents defend well? It sure looks like three heart losers and one club loser, doesn't it?.
The spectators claimed that the contract is always off if South is awake. Were they correct?
If you are advanced or better, please use hidden text, and if you are a B/I, don't peek if they do.
