South leads the

Next comes the
♥7,3,A,5.
Then comes the
♣2,7,J,K.
Our perceptive South, noting the missing
♥4 decides his partner must be starting the famous Smith Echo to announce the original holding of QJ3 in the North. Confidently our South leads
♠6 but the declarer chalks up +630 with 2 spades, 4 clubs, and 4 hearts.
Meanwhile in the closed room 3NT is beaten 5 tricks (4 diamonds, 4 spades, and the club K). How much is 1130, some 15 IMPs?
Sometimes you get the bear... sometimes the bear gets you.
Your example is not a good one.
1stly, few good players (if any) would win the club K on the first hook....most would duck on general principles, and on your example, the cat would be out of the bag should declarer attempt to cross in hearts again, even if he led the Q on the second round.
2ndly, if one plays smith, N would have a far clearer come on in hearts than the 5. How about the 9? I doubt that many N's would see any need to keep the 9 in their hand, if they had QJx in spades and played regular smith!
It is possible to construct hands on which any device fails, whether it be Smith, Reverse Smith, udca, odd/even and so on. But your effort wasn't valid.
You might also want to take a constructive lesson from this. That is: when you want to send a message, make it as clear as you can afford to. Thus, as N, were you playing regular smith, and you hold 9854, whatever you do don't play the 5!!!!!!! Play the f&*king 9....don't play the 5 and then blame partner for not reading it
No expert player would fall for the play you described simply because no expert player would play partner to play the 5 from 9854/954/854. Of course, on a different day, where the red suits were switched and if opener has Q987 in diamonds, opposite AKJ10, the bear may well have bitten us, but even then only if we are dumb enough to win the first club. Once we duck, partner gets to play the 4 the next time and we can work it out.
