Not Suspicious

I am playing in a regional one-session Swiss and don't know my opponents. As dealer, I pick up  S:J742 H:K D:AK974 C:QJ10. I open 1D:, partner bids 1NT, and RHO bids 2S:. This is clearly not their best spot, since they have nine or more hearts, so I pass. Not surprisingly, this ends the auction. I lead a high diamond and see

Partner contributes the D:8, upside-down attitude. I shift to the C:Q, which holds. It looks as if declarer is 6-4-2-1 exactly. I could cash another diamond and exit with a club, but I have a sneaky plan. I don't want to give away that I have a third club, so I continue with the C:J. Declarar ruffs this and plays a diamond to me. Acting like a man who has only two clubs, I continue with a third diamond. This has two effects: I allow declarer acess to dummy to take a heart finesse, and it sets up my winning diamonds, which I can use once declarer's trumps are shortened. Declarer is not suspicious (why didn't I cash the D:A at Trick 3?) and hooks into my H:K. I continue with my club, and declarer ruffs. He cashes two high trumps, and partner's S:Q falls. Thinking that he needs trumps 3-3 to make 2S:, he continues with a third trump. I win and lead my good diamond, forcing out declarer's last trump. He tries to cash the H:A, but I ruff and cash a winning diamond for down two and a beer.

The whole hands was

The Trojan Horse Coup is an old chestnut, but this time it served double-duty by setting up diamond winners to continue the tap later. Declarer lost his way several times, but I'm glad my play was allowed to work.
