Grob vs C Chaude de Silans, 1951

Chessgames offers us a beautiful picture of Henry Grob, playing an exhibition match vs. French Lady Chantal Chaudé de Silans, one of the rare non-soviet female chess stars after World War II:>

Grob donated his whole chess life in promoting the 1.g4 opening (subsequently introducing his own name), he played hundreds of games with 1.g4 in the <NZZ Fernschachzentrale> (correspondance chess against readers of the noble 'Neue Zürcher Zeitung') and published the book GROB's ANGRIFF:

1. For the games conducted during WW2, there was no charge for any soldiers, officers or auxiliaries of the Swiss defence forces who wanted to play Grob, while private civilians had to pay a fee of 4 Swiss francs by a postal cheque. After the end of WW2, there was a flat fee of 2 Swiss Francs for anyone who wanted to play Grob.

2. Players could choose to have either the white or black pieces.

3. Moves were not transmitted by postcard, which would have been impractical and also difficult due to the need for secrecy. Instead each game was given a number and the morning editions of the NZZ published lists of the latest moves. Grob's opponents only had to read the newspaper to see Grob's latest move. They responded on postcards, citing the game number and the latest moves. The postcards were originally sent to the NZZ offices, although later games were sent to Grob's home address.
