Remembering Percy Francis Blake (6-xii-1873 26-iii-1936)
From The Encyclopaedia of Chess (Batsford, 1977), Harry Golombek OBE, John Rice writes:
“British problemist, regarded as one of England’s finest composers, Blake produced direct-mate problems in two, three and four moves.”
From his Italian Wikipedia entry :
“Percy Francis Blake ( Manchester , December 6, 1873 – Grappenhall , March 20, 1936 ) was a British chess player and chess composer , among the best English problem players of the period 1900 – 1936 .
He composed over 500 problems, most in two and three moves, of which around 160 were awarded (45 first prizes and 40 second prizes). 
He was famous for “quiet” keys and continuations, which made his problems very difficult to solve.
He was also a good player and table. In 1890 he won the Manchester club championship and later several local tournaments. In 1894 he won a beauty prize offered by the Manchester Weekly Times . From 1898 to 1912 he was part of the Lancashire team in many team matches between that county and Yorkshire . In 1911 he won the Lancashire championship. ”
