He heard Zia Mahmood pass on his right. On the surface of it he has only a marginal opening bid, and no comfortable rebid if he commences proceedings by bidding 1+. Should he open the bidding, and if so, with what bid?
This is one of the problems analysed in the programme. Answer in next week's Radio Times.
Problem set by Barry Rigal.

Trade Gap: the Spectre at the Feast
Ten years ago this week, a Conservative government came to power committed to a radically different approach to managing the economy. A decade later, the United
Kingdom faces an all-too-familiar problem - a huge trade deficit. Why has
Mrs Thatcher 's supply side policy so far failed to make an impact on Britain's deep-seated tendency to import? Nisha Steyn reports. Producer JEREMY BRISTOW
Deputy editor CHRISTOPHER GRAHAM Editor DAVID NISSAN

by TERENCE RATTIGAN.
Ronnie Winslow , a naval cadet, is expelled from
Osborne for the alleged theft of a five-shilling postal order. His family begins a long and costly fight to prove his innocence, a fight that finally shakes the government of the day.

Day 16 draws to a close; the long haul is nearly over, but what price the thoughts of more than 100 players who would no doubt cheerfully swap places with the two men under pressure. Suffering sometimes has its advantages!
