At matchpoint duplicate bridge, not weak vrrsus weak, and sitting West, I held

♠ AK32
♡ J643
♢ 6
♣ JT82

Partner (East) opened one coronary heart, South overcalled one spade, I raised to 2 hearts, North bid two spades, and there have been three passes, giving me the opening lead.

I led my diamond singleton, and (FWIW) dummy got here down:

♠ JT95
♡ A
♢ JT92
♣ KQ64

Partner requested me why i did not lead her coronary heart go well with. I identified, with the good thing about hindsight, that dummy had a singleton ace, which means that we might not take methods in that go well with. Even with out the “look,” I feared that given my associate’s and my coronary heart size, one of many opponents would have a singleton (or void).

Given my singleton, I needed to have the ability to ruff diamonds with my little spades. I had two trump “stoppers” and I needed to save lots of associate’s (presumed) coronary heart entry so she could lead on diamonds.

I may not have performed this with the spade KQxx or QJxx as a result of I might the “little” playing cards to guard my honors. But right here, I assumed greatest use of the three and a pair of could be as ruffers.

Was I proper to steer my singleton? Or was associate proper to insist on a coronary heart lead? Or maybe the error was that neither of us bid three hearts earlier?
