This hand puzzled me from the Aussie-England match.

1D was a transfer opening, showing 4+Hs 9-14. North clearly intended 2H as if West had passed - 3+Hs, 6-8 (4Hs only if balanced). East showed a singleton/void in Cs with spade support, game going values, and now South was not on the same page as North - first North cuebids 4S to show a singleton/void in spades, and then raises 5C to 6C. South's sequence looks like he forgot he showed hearts with 1D! The result was -1400 and -16 IMPs and an awful start to this event for this pair.
