Matchpoint pairs
Dlr: South
Vul: Both

In principle North-South play an Aussie variant of Acol. The uncontested
North-South auction proceeds:

1C (Announced as 4+ clubs) - 1S - 2S - 6S - all pass

You, East, hold:

---
542
8642
K86432

What opening lead do you make?
What opening lead(s) would be a Serious Error?

Best wishes,

Richard Hills
