Stevenson Memorial — Southsea 1950

◇Penrose among the leaders

Jonathan Penrose, Harry Golombek and Lothar Schmid finished half a point behind the joint winners. Sixteen-year-old Penrose beat Bogoljubow, Prins and Tartakower and received the Southern Counties Chess Union championship. The original Chess Bulletin prints his complete win over Tartakower, ending 39.Be7 mate.

◇The original Swiss ledger

The original Bulletin table records all 42 entrants and 210 scored pairings. Commander Graham Powell Britton left after six rounds; Golombek’s contemporary report, reproduced by BritBase, says that his last four games were forfeited. The original table gives ordinary win/loss entries without default suffixes. Removing those four unplayed pairings leaves 206 physical games.

Britton’s second-round win over Heneage and third-round loss to Watson are explicit in the original table. A later transcription gives two draws instead. The original entries reconcile with the opponents and all 42 totals. Searches through every played pairing, aliases and nearby source years found no additional native score.

◇Preserving the scores

The original roster identifies H. H. Cole and E. Reifenberg: Henry Holwell Cole and the Cambridge mathematician Ernst Robert Reifenberg. The two affected native scores had named Harold Godfrey Cole and Reifenberg with the wrong initial; the archive restores their documented identities.

Bogoljubow–Barden and Prins–Fry belong to round two, and Bruce–Knight to round nine. Their event memberships follow the published ledger while each source Game and PGN keeps its original round tag. All moves, results and year-only dates remain intact.

All 52 native mainlines match the later BritBase comparison. Penrose–Tartakower was also checked in full against the original printed score. The later comparison is not claimed as an independent witness for every move. The complete Swiss table is linked below; this partial game collection is not used to compute substitute final standings.
