Some study tries by

Charles Edward Ranken

(England, 5.1.1828 - 12.4.1905)

At Wikipedia we can read a lot about him.

This is his chess career:

Ranken was a leading member of a group of clerics who played a prominent role in early Victorian Era English chess.[4][11]

In addition to Ranken, these included the Reverend George Alcock MacDonnell, John Owen, William Wayte, Edmund Thorold and Arthur Skipworth.[11][12]

Mike Fox and Richard James remark that, "The English parsons were a talented mob; presumably quiet country parishes in the nineteenth century gave one the leisure needed to become a star."[13]

However, Philip Sergeant in his book A Century of British Chess writes that, "In chess he was one of the writing rather than the fighting clergy, and his delight lay most in analysis".[3]

Despite Sergeant's characterization, Ranken played in a number of tournaments in Britain between 1851 and 1895.[14]

After leaving Oxford, he played in the provincial section of the great London 1851 tournament, finished second behind Samuel Boden.[4][15][16]

By 1859, the Chess Player's Chronicle ranked him the best English player outside London.[17] He played in many congresses organized by the Counties Chess Association.[4]

His best result was in 1872, when he finished first in the first-class section at the 8th British Counties Chess Association Congress in Malvern with 12 of 14 possible points,

ahead of Revs. Thorold (11.5 points) and Wayte (10.5 points).[4][7][18]

He had another excellent performance in 1881, when he won the 16th British Counties Chess Association Congress in Leamington, scoring 8 of 9 possible points,

ahead of Revs. Owen (7.5 points) and Wayte (7 points).[19] n 1877, he won the Counties Chess Association handicap tournament at Birmingham.[20]

At the 1883 London Vizayanagaram minor tournament,[21] Ranken "started well but his health gave way after the first week".[4]

He still scored 17.5 of 25 possible points, tying for 5th–6th out of 26 players with George H. D. Gossip.[22][23][24] Curt von Bardeleben won with 21.5 points;

Isidor Gunsberg, who would narrowly lose an 1890–91 World Championship match to Wilhelm Steinitz, finished fourth with 19 points.[22][24]

The strongest tournament in which Ranken played was the Master Tournament at Hereford 1885, an 11-player tournament that featured some of the world's leading players.

Ranken scored 3 of 10 possible points, tying for 8th–10th with William Pollock and Thorold.

Joseph Henry Blackburne won with 8 points, followed by Henry Bird and Emil Schallopp (7.5 points), George Henry Mackenzie (7 points), and Gunsberg and James Mason (5.5 points).[25]

Ranken also participated in several correspondence chess matches and took first place in the British Chess Association's 1872 competition.[26]

Sadly his few Endgame compositions are not without cooks.

But his ideas let to some corrections by others.
