In connection with J C Thompson's birthplace, Paul McKeown wrote:Can anyone shed light on this mystery?
Following Paul Mckeown's and Richards James's bits on the Hippopotamus opening I did some ferreting around and have unearthed a few points which convince at least me that J C Thompson was probably born in India and the Hippopotamus opening probably has its roots in a variant of Indian Chess. There is a less likely possibility that he was born in Wales.
It is believed Thompson was born in 1889. There are two 12 year old J C Thompsons in the 1901 census. One of these is shown as born in Wales; the other India Travanmore, which I suspect is an OCR error for Travancore, and during 1901 lived in London. Several points make India more likely.
Firstly there was a version of Indian Chess popular around the late 19th century in which pawns could only move one square on the first move. Apart from that the game was mostly similar to European Chess but the black king and queen started the game on d8 and e8 respectively.
Secondly the 1904 BCM reviews a book by Lala Raja Babu Sahib about this version of Indian Chess, which describes an opening for black which starts 1.e3 f6 2. d3 e6 3.c3 g6 4.e4 Bg7 5.g3 d6 6. Be3 c6 7.Na3 Ne7 8.Qb3... resulting in this position:-

If that doesnt look like a hippopotamus system then what does? Bearing in mind that black's K-side is really the Q-side its even more like a Hippo. I doesnt take too much of a guess to think that Thompson probably learnt the game as a child in India and used these early influences to develop his own style.
On the other hand it could just all be coincidences - cue for James Plaskett to join this forum.
