He seemed to reach a strong level for someone of that age though, as played high boards for Hampshire (up to bd 4).

The fact that there is a Chapman Cup in Kent, and there was one in Hampshire and Dorset links to this being named after the same person (as not many people want cups named after them?)

The references always seem to say CF for Dorset and Hants but C for Kent (did not play for Sussex against Hampshire). But the board numbers he played on do seem consistent with being one player (or someone of the same strength). The Dorset Individual Championship was originally the Chapman Trophy

All I had was the details which said he was also involved in Sussex before Dorset. I have a C Chapman playing for Kent against Hampshire from 1900 - 1911. If this is the same person may help? email is g.b.stuart@btinternet.com which may help discuss further?

Not too much afraid, the FL Taylor booklet on the site has a few references - made Life VP in 1936 when he left the county and he was very generous with sponsoring the KO tournaments.
The Hampshire Advertiser and Western Daily Press are good sources and he was President of Dorset from 1929?

Just added a post on HCA County records, and added some additional details on Blake's impressive record.

Yes, would be great to see this. A huge chess career and someone who helped Hampshire no end by playing board one for such a long period.
