I’m sad to hear of the death of PH Clarke, who died in Morwenstow a few days ago at the age of 81. He was one of the few amongst the top British players who took an interest in chess problems and, until the last few years, he had been a regular finalist at the (Winton Capital) British Chess Solving Championship, his best result being third (behind Jonathan Mestel and Tony Lewis) in 1982-1983. I met and conversed with him several times over those years and I remember an unfailingly polite and modest man. The British Chess Magazine has posted a short obituary at their site.
I have now finished marking the Postal Round and full results are available here.
