There’s a rather sublime equilibrium to Arthur Miller’s 1968 play between the overwhelmingly heavy weight of history and a sheer life force that somehow functions, against all odds, as its counterbalance.

"In our country the capable man needs luck," belts out Shen Te, the Good Person of Szechwan in the most powerful song of Brecht's epic "parable play" of 1941. "Only if he has powerful backers can he prove his capacity." Never was that more true than in Russia today; note that the Moscow Pushkin Drama Theatre has been resident at the Barbican for five days "with the generous support of Roman Abramovich".

So here we are with another edition of IQ, and the subject this week is theatre. Question one: which actor originated several leading roles in the plays of George Bernard Shaw, including Marchbanks in Candida, Dubedat in The Doctor's Dilemma, and Jack Tanner in Man and Superman? Answer: Harley Granville Barker. Question two: which writer originated the use of the Royal Court Theatre in Sloane Square as a home for new plays and rediscovered classics?

What's worse than grieving? That all-consuming loss. For those that have experienced it, nothing really comes close. It starts to bug Thomas (Jordan Bernarde, main picture second right) during his visit to the Williams household. Recently bereaved himself, he senses the fragility in the air but no-one seems to give a straight answer. Everyone would rather focus on him, talking at speed but never really engaging beyond the surface.

It was back to the very beginning for this final instalment of “Pinter at the Pinter”, with its pairing of A Slight Ache and The Dumb Waiter. Both were written at the end of the 1950s, which explained a certain rock’n’roll vibe in the auditorium, but brought home how much Pinter’s work stretches beyond period, resounding with new intonations to match new times.

The Fifties? They were terrible: bone-cold houses where people huddled round the fireplace for heat, empty Sundays that lasted a month, drawn-out rationing, bread you could build houses with.

There is no doubt that this Cherry Orchard, whirled into town by Roman Abramovich from Moscow, is going to be divisive. If you, like the two elegant old gentlemen sat next to me on press night, have come to see the Pushkin Drama Theatre’s production in order to steep yourself in Chekhov’s philosophical ambiguities and perhaps brush up on your Russian, you will be disappointed.

In the history of early photography in the Middle East, it was the Armenian Christian traders and their descendents who became the pioneers of the new technology. Their numbers include the Armenian-Turkish photojournalist Ara Güler, "the Eye of Istanbul" who died last year and was famous for his signature images of the city.

Titles matter: they send out messages. So, in the current #MeToo climate, isn't it a bit provocative that there's a rash of plays with titles which might be seen to offend: The Hoes, Superhoe and, coming soon, Inside Bitch? Not to mention the suggestive Hole. All strong titles, tough and spiky. But maybe not offensive at all. These plays are, after all, all written by women, and nowadays it's not what you say, but who says it that really matters.

The Off Broadway production of Cost of Living two years ago brought Martyna Majok the 2018 Pulitzer Prize for Drama, the height of acclaim of which most new writers – Majok, with four plays behind her, has yet to turn 35 – can only dream.
